1. Background

The Complexity of Mixing Hairstrokes and Powder Brows Pigments Mixing pigments for Hairstrokes and Powder Brows is a nuanced process, often seen as perplexing due to the varied factors involved. This complexity can lead to challenges for even seasoned professionals. To provide clarity, we sought insights from 36 artists specializing in Powder Brows and Hairstrokes, complemented by expertise from two chemists. These artists, primarily from the European Union and several from the U.S. and U.K., shared their experiences and best practices for mixing pigments from different brands and origins.

Colorimetry vs. Chemistry in Pigment Mixing

To understand the intricacies of pigment mixing, it's crucial to differentiate between colorimetry and chemistry. Colorimetry offers theoretical knowledge on how colors are perceived based on color theory. It helps artists predict how different hues will blend visually. Chemistry, however, delves into the physical and chemical composition of pigments. This aspect is particularly critical as it influences how pigments react with each other and the skin. Understanding colorimetry and chemistry is essential for successful pigment mixing, as factors affecting color perception and pigment behavior can significantly differ from theoretical color blending expectations.

By integrating these aspects, artists can make more informed decisions about pigment mixing, leading to desired outcomes in both color and texture. This approach helps overcome common misconceptions and challenges in pigment blending, ensuring more consistent and satisfactory results in semi-permanent makeup applications.

2. Fundamentals of Colorimetry

A serious-looking professional woman is on the left, and a color wheel with warm and cold colors and opposite colors is on the right.

Primary Colors and Their Significance in Pigmentation

In the realm of colorimetry and pigment analysis, the primary colors - red, yellow, and blue - are pivotal. These fundamental hues form the basis of all other colors and are essential in the field of semi-permanent makeup. Primary colors cannot be created by mixing other hues. Understanding their properties and interactions is crucial for semi-permanent makeup artists, especially when it comes to creating desired brow shades or neutralizing undesired tones.

Secondary Colors: The Result of Primary Mixes

When primary colors are mixed, they yield secondary colors like orange, purple, and green. This principle is critical in pigment selection for cosmetic procedures. For instance, blending blue and yellow produces green, while mixing red and yellow creates orange. Knowing how to combine primary colors to achieve these secondary hues enables artists to tailor pigments to the specific needs of their clients, such as correcting or enhancing natural brow colors.

Tertiary Colors and Their Role in Brow Pigmentation

Tertiary colors emerge from mixing primary and secondary colors. These combinations lead to shades, including grays and browns, which are particularly useful in achieving more natural-looking brow colors. For example, combining blue with an orange-leaning hue results in a specific gray shade, while red, green, yellow, and violet create unique grays. Mastery of these tertiary color combinations allows artists to fine-tune pigments for more personalized and accurate results.

Utilizing the Color Wheel for Complementary Colors

The color wheel is an indispensable tool in pigment selection, categorizing colors into primary, secondary, tertiary, complementary, and neutral groups. Understanding complementary colors, which sit opposite each other on the color wheel, is crucial for counteracting unwanted shades. For instance, a pigment with green undertones is used to neutralize red, violet is balanced with yellow, and blue is offset by orange.

Color Temperatures: Warm, Cool, and Neutral

Colors are also characterized by their warm, cool, or neutral temperatures. Orange is the warmest color, while blue is the coolest. Recognizing the temperature of colors aids in selecting the right pigment for each client. Light colors emphasize features, making them appear larger, whereas dark colors diminish their effect. This knowledge helps achieve the desired visual impact, whether to accentuate or subtly enhance the natural beauty of the eyebrows.

3. Correction logic

A serious-looking professional woman is on the left, and four color combinations are on the right, targeting the brown brow color.

Salmon Pink Eyebrows: Neutralizing with Olive

When dealing with salmon pink eyebrows with a strong red base, the objective is to neutralize the red to achieve a natural brown hue. The complementary color to red on the color wheel is olive, a blend of yellow and blue. An olive-toned pigment or modifier effectively counterbalances the red, shifting the color toward brown. This approach is crucial for artists who frequently encounter salmon-pink eyebrow corrections.

Cool Gray Eyebrows: Transforming with Orange

The key to achieving a brown shade for eyebrows that exhibit a cool gray or blue-based tone is using orange, a mix of red and yellow. As orange sits opposite blue on the chromatic wheel, it is the perfect counteracting color. Employing an orange modifier or a pigment with a significant orange content neutralizes the blue undertones, leading to a warmer, brown appearance. This technique is essential for artists correcting gray or cool-toned eyebrows.

Greenish Eyebrows: Balancing with Warm Chestnut

Greenish eyebrows, characterized by their green base, require a warm chestnut color for neutralization. Chestnut, a combination of brown and red, effectively balances the green, transitioning the color to a natural brown. To achieve this, artists should opt for a pigment or modifier that contains warm, reddish undertones. This strategy is particularly useful for adjusting greenish-toned eyebrows to a more desirable brown color.

Purple or Dove-Colored Eyebrows: Covering with Yellow

The missing component is yellow in the case of purple or dove-colored eyebrows, which combine blue and red. Yellow or mustard modifiers are needed to neutralize the purple and achieve a brown tone. This approach involves covering the purple base with a yellow shade, effectively transitioning the color to brown. Selecting the right yellow-toned pigment is crucial for artists with purple or dove-colored eyebrow corrections.

Therefore, understanding the logic of color correction in semi-permanent makeup involves identifying the base color of the eyebrows and selecting the appropriate complementary color to neutralize it. These practical examples provide artists a clear roadmap for effectively modifying existing eyebrow tones to achieve the desired natural brown shade.

4. Pigment Colorants

The Core Pigment Colors are black, Red, and Yellow

In the realm of semi-permanent makeup, specifically techniques like Powder Brows and Hairstrokes, the foundational colors are Black, Red, and Yellow. A deep understanding of these pigments' primary sources and chemical composition is essential for artists to grasp the nuances of pigment properties and the intricacies of color mixing.

Organic vs. Inorganic Pigments: Chemical Classifications

The classification of pigments into "organic" and "inorganic" categories is based on their chemical composition, particularly the presence or absence of carbon-hydrogen (C-H) bonds.

Organic Pigments: These compounds contain carbon-hydrogen bonds and are often associated with living organisms. However, organic pigments can also be synthesized in laboratories. They are known for their complex structures and are utilized in various applications, including dyes and cosmetics. In semi-permanent makeup, organic pigments are valued for their bright and vivid colors but may have shorter longevity and higher fade rates.
Inorganic Pigments: Lacking carbon-hydrogen bonds, inorganic pigments are simpler in structure. They are not derived from living organisms and can be found naturally, like minerals, or manufactured in labs. In the context of semi-permanent makeup, inorganic pigments usually offer more subdued colors. However, they are prized for their longer-lasting effects and are less likely to cause skin sensitivities or allergic reactions.

Implications in Semi-Permanent Makeup

Understanding whether a pigment is organic or inorganic is vital for several reasons:

Color Intensity and Variety. Organic pigments can provide a broader range of intense colors, which can be advantageous for achieving specific aesthetic goals. However, this intensity may come at the cost of faster fading.
Longevity and Safety. Inorganic pigments, while less vibrant, are often preferred for their durability and lower risk of skin reactions. This makes them a safer and more reliable choice for clients concerned about pigment longevity and skin sensitivity.
Informed Decision-Making. Knowing the chemical nature of Black, Red, and Yellow pigments allows artists to make informed decisions when selecting pigments for specific procedures. This knowledge is crucial for color mixing, ensuring the safety and satisfaction of clients.

Therefore, the distinction between organic and inorganic pigments is fundamental to semi-permanent makeup. By understanding these pigment types' chemical properties and practical implications, artists can enhance their color mixing skills, choose pigments wisely, and ultimately deliver better results in Powder Brows and Hairstrokes procedures.

5. Organic and Inorganic Sources

Black Pigments

Organic. Carbon Black (CI 77266), derived from the incomplete combustion of carbon-rich materials like tar and oils, is a primary source for black organic pigments. It offers a deep, intense black shade, making it a preferred choice for creating striking, bold effects in semi-permanent makeup.
Inorganic. Iron Oxide Black (CI 77499) represents the inorganic alternative. This pigment is created by oxidizing iron to produce a stable, non-toxic black pigment. Its popularity stems from its safety profile and consistent color retention over time.

Red Pigments

Organic. For red shades, synthetic dyes such as D&C Red No. 7 (CI 15850) and D&C Red No. 6 (CI 15850), made from coal tars, are commonly used. These organic pigments are celebrated for their vibrant and bright red hues.
Inorganic. Iron Oxide Red (CI 77491) is the go-to source for inorganic red pigments. The oxidation process of iron results in a stable red color that is favored for its natural appearance and durability.

Yellow Pigments

Organic. Tartrazine (CI 19140) is a widely used organic source for yellow. This synthetic azo dye is notable for its intense, lemon-yellow coloration.
Inorganic. Chrome Yellow (CI 77600), essentially lead(II) chromate, is used in inorganic pigments. However, toxicity concerns make it less prevalent in cosmetic applications. Iron Oxide Yellow (CI 77492) is a safer inorganic alternative, offering a warm, earthy yellow tone.

Color Mixing and Chemical Considerations

When mixing these pigments, understanding the percentage composition of each color is critical. This knowledge enables precise adjustments to achieve the desired shade. For example, adding yellow or black can help attain a balanced brown tone if a pigment is predominantly red.

Inclusion of Green and White Colors

Green. In the chemical context, green is often achieved by mixing blue and yellow, the complementary color of red. This principle is crucial in color correction, especially when neutralizing excessive redness in semi-permanent makeup.
White. Typically achieved with titanium dioxide, white enhances the reflectivity and brightness of pigments, preventing them from fading into duller versions. Titanium dioxide helps maintain the vibrancy and clarity of pigments over time.

Thus, the choice between organic and inorganic sources for Black, Red, and Yellow pigments and the strategic use of green and white plays a crucial role in achieving the desired effects in semi-permanent makeup. Understanding these chemical principles is essential for artists to effectively mix pigments and deliver precise, lasting results in their Powder Brows and Hairstrokes applications.

6. Marketing of pigment bundles

The Basics of Pigment Composition In the semi-permanent makeup industry, various pigment bottles with different names and promised shades can be overwhelming. However, at their core, these pigments are generally composed of three primary colorants: Black, Red, and Yellow. Whether these colorants are of organic or inorganic origin, they form the basis of most pigments available on the market. The key distinction between different pigment bottles, such as "Cherry Blossom Red" and "Ruby Red," often lies in the ratio of these primary colorants. The unique shades result from varying proportions of black, red, and yellow rather than entirely distinct chemical formulations.

Commercial Strategy Behind Pigment Varieties

The extensive range of labeled pigments serves a significant commercial purpose. Manufacturers can create more extensive product lines and collections by offering an array of specific shades. This strategy entices consumers to purchase multiple bottles for various effects or the 'perfect' shade. Such marketing tactics aim to boost sales by appealing to consumers' desires for a wide range of color options and specific effects.

Practical Implications for Artists

For semi-permanent makeup artists, understanding the basics of color theory and pigment composition is empowering. Knowing how primary colors interact and their ratios allows you to mix primary pigments to replicate various shades without purchasing every color manufacturer’s offer. This approach simplifies the color selection process and offers cost-effectiveness and creative control.

Industry Trends and Consumer Awareness

It's worth noting that many pigment manufacturers have recognized the limits of consumer naivety. In response, there has been a trend towards simplifying pigment offerings, reducing the number of creative and seemingly unique mixes. This shift reflects a growing awareness among makers and consumers of the fundamental principles underlying pigment composition and color theory in semi-permanent makeup.

7. Practical mixing

The Principle of Gradual Darkening

When mixing pigments for semi-permanent makeup procedures like Powder Brows and Hairstrokes, understanding the principle of gradual darkening is key. Unlike altering the chemical structure, mixing pigments involves combining different color molecules on the skin. This changes the visual appearance of the color in the brows but not the pigments' intrinsic chemistry.

Starting with Lighter Base Colors

The unchangeable chemistry of mixed pigments means that the resulting color will always be darker, never lighter. Therefore, the optimal strategy is to start with lighter base colors, such as yellow-based or red-based orange and light brown hues. This method allows for incremental darkening by adding black color to a darker pigment. This gradual approach provides control and flexibility in achieving the desired color.

Avoiding Reverse Mixing

Attempting to lighten a dark pigment is ineffective and often leads to unsatisfactory results, such as overly dark brows. Since adding darkness to a color is simpler than lightening it, it's crucial to begin with a lighter hue and then adjust the darkness as needed.

Conserving Pigment and Achieving Precision

You can precisely reach the target shade by starting with a lighter base and cautiously adding darker tones. This approach not only ensures accurate color matching but also conserves pigment. It minimizes the risk of ending up with darker brows than intended, ensuring client satisfaction and maintaining the integrity of your work.

8. Two pigments is generally sufficient

Opt for Two-Pigment Mixes

For creating new shades in semi-permanent makeup procedures like Powder Brows and Hairstrokes, limiting your mixes to two pigments is advisable. This approach is grounded in practicality and the basics of pigment chemistry.

Chemistry Unchanged. Mixing multiple pigments doesn't create new chemical colors. The fundamental chemistry of the pigments remains intact; the process only introduces additional color molecules to the skin.
Consistency and Replication. A two-pigment mix is easier to replicate for future applications. When you start blending three or more pigments, the complexity of the mix escalates, making it challenging to achieve the same color consistently.
Business and Marketing Influences. Some training courses or trainers might promote the use of multiple pigments. However, this often stems from business objectives or marketing strategies rather than scientific necessity.

Simple Ratios for Consistency and Efficiency

When mixing pigments, straightforward ratios like 1:1 or 2:1 are recommended, where the lighter pigment typically forms the larger part. These ratios are practical for several reasons:

Consistency. Simple ratios enable easy replication of the same color mix for different clients, ensuring uniformity in your work.
Efficiency and Waste Reduction. Simple ratios are more efficient and result in less waste. Complicated ratios can lead to excess pigment preparation, leading to unnecessary wastage.

Debunking “Secret Ratios”. The concept of complex or "secret" ratios often propagated in training sessions is more of a marketing gimmick than a necessity. These ratios add unnecessary complexity without offering any real benefits.

Therefore, for successful color mixing in Powder Brows and Hairstrokes, adopting a minimalist approach with two-pigment mixes and simple, consistent ratios is key. This strategy ensures consistent color reproduction and streamlines your workflow, saving time and resources. Remember, the art of pigment mixing lies in its simplicity and understanding of basic color theory rather than in overcomplicating the process.

Color Selection Based on Skin Subtone

Understanding the subtone of your client's skin is crucial when selecting and mixing colors for Powder Brows and Hairstrokes procedures. Here's a simplified approach to choosing the right color based on skin subtone.

Pink Subtone

Characteristics. Skin that appears pinkish often reddens and is typically accompanied by cool eye colors.
Color Approach. Utilize olive pigments to neutralize the redness. Olive, a mix of yellow and blue, effectively counters the red undertone, providing a more balanced appearance post-procedure.

Greyish/Bluish Subtone

Characteristics. Pale skin has cool undertones, often cool lip and eye colors, and blue wrist veins.
Color Approach. Opt for warm pigments with a high orange content. Orange, a blend of red and yellow, is the perfect counterbalance to the blue undertone, ensuring a neutral shade post-healing.

Golden Subtone

Characteristics. Warm skin and eye tones, with wrist veins appearing green.
Color Approach. Clients with a golden undertone can generally carry neutral or warm colors well. Pigments based on yellow, green, or orange bases are suitable for this subtone, complementing the skin's natural warmth.

Olive Subtone

Characteristics. A swarthy or tan complexion with warm eyes and lip tones.
Color Approach. Neutral colors with an olive base are most effective for olive subtones. These pigments harmonize with the natural greenish undertone of the skin, achieving a balanced and natural result.

By carefully analyzing the client's skin subtone and selecting pigments accordingly, you can ensure a more harmonious and natural-looking outcome for semi-permanent makeup procedures. Remember, the goal is to counterbalance the natural skin tone with complementary colors, not to match it exactly. This approach helps achieve a more realistic and aesthetically pleasing result that complements the client's natural features.

10. Identifying Pigment Subtones

Pigments in the bottle show their "mass tone" or concentrated color. However, their "subtone" or true color, which is crucial for color matching, is revealed through drawdown.

Drawdown Technique

Apply a small amount of pigment on a piece of paper using a cotton stick. Extend the line until the pigment thins out, revealing the pigment's subtone.

Performing Drawdown for Accurate Color Insight

Procedure. Perform drawdowns on original, unmixed pigments and any potential mixtures you're considering.
Visualization. This technique helps visualize the pigment's true color, aiding in selecting the most suitable combination for the client's natural brow color.
Simplifying the Selection Process
Ready Reference. Having readily available drawdowns of commonly used pigments and mixtures can streamline the color selection process.
Accuracy. Using drawdowns ensures you're working with the pigment's true color, enhancing the accuracy of the color match.

By mastering the drawdown method and focusing on the natural brow hair color, artists can achieve a harmonious color match that complements the client's features and ensures a more natural and appealing result. This approach is fundamental in delivering high-quality semi-permanent makeup services.

11. Diluters and modifiers

In the art of semi-permanent makeup, like Powder Brows and Hairstrokes, achieving the perfect pigment consistency and color is crucial. This requires an understanding of how diluters and modifiers function. Here's a breakdown of their roles and how they impact the mixing process:

Diluters: Enhancing Fluidity without Altering Chemistry

Primary Function. Diluters are designed to make the pigment more fluid without changing its chemical composition.
Usage. They are particularly useful when the pigment is too thick for precise hair strokes or shading techniques.
Effect. Diluters are an extension of the pigment's liquid carrier, especially the solvent part, ensuring smoother application and consistency.

Modifiers: Potent Color Adjusters

Impact on Color. Modifiers significantly affect the pigment's color. They are potent and can drastically change the shade with even a small addition.
Usage in Special Cases. Modifiers are beneficial for adjusting the pigment's appearance on specific skin types. For instance, on oily or thick skin, where pigments might appear grayish, adding a yellow or greenish-olive modifier can neutralize the gray undertone.
Careful Application. Given their strong impact, modifiers should be used cautiously to avoid unintended color shifts.

12. Lightfastness

Lightfastness is crucial in determining pigments' durability and color consistency in semi-permanent makeup techniques like Powder Brows and Hairstrokes. Let's delve into this concept and its implications for pigment selection and application:

The Essence of Lightfastness refers to a pigment's capacity to resist fading or color changes when exposed to light, particularly UV rays from the sun or artificial lighting.
Importance: High lightfastness ensures the color remains stable and true over time, crucial for maintaining the desired appearance of semi-permanent makeup.

Measuring Lightfastness: The Blue Wool Scale

Scale Range. The Blue Wool Scale, used industry-wide, ranges from 1 (least lightfast) to 8 (most lightfast).
Artist’s Guide. This scale helps artists understand the longevity and stability of each pigment, influencing the choice of colors for blending.
Fading and Degradation. Over time, pigments in the skin naturally fade, a process hastened by light exposure. Ingredients with varying lightfastness levels may fade unevenly, leading to inconsistent or patchy colors.
Color Changes Over Time. Due to this inconsistency, some pigments may age into different hues, resulting in ashy or warm tones as they fade.

Formulating Pigments with High Lightfastness

Stable Ingredients. Pigments with high lightfastness and compatible ingredients are formulated to fade gradually, maintaining a softer version of the original color.
Retouching Advantage. Such pigments facilitate easier retouching, ensuring consistent, long-lasting color results.

Practical Testing: The Ultimate Indicator

Drawdowns as Initial Indicators: While drawdowns can provide some insight into how pigments might fade, they are not definitive.
Real-World Testing: Seasoned artists emphasize that the true test of a pigment’s lightfastness is observed in its behavior on clients' skin over time.

Understanding lightfastness is essential for semi-permanent makeup artists. It allows for the selection of pigments that will provide beautiful initial results and ensure those results age gracefully and maintain their intended appearance over time. Practical experience and observation remain key to comprehending how pigments behave in real-life applications.

13. Tyndall Effect and Natural Cooling

The Tyndall Effect and the concept of Natural Cooling are crucial in achieving the desired outcomes in permanent makeup procedures, such as Powder Brows and Hairstrokes. Let's explore these phenomena and their implications.

Tyndall Effect: Light Scattering in Skin

Basic Concept. It refers to the scattering of light in colloidal dispersions, which relates to how light interacts with pigments in the skin in the context of permanent makeup.
Depth Impact. The deeper the pigment is placed in the skin, the darker and cooler it appears due to the Tyndall Effect's influence on light and color perception.

Natural Cooling of Pigment

Healing and Color Shift. As the skin heals post-procedure, typically over 30-45 days, pigments often appear duller and adopt cooler or ashier tones.
Natural Cooling Defined. This shift in color during the healing process is termed "Natural Cooling.”

Combating Natural Cooling

Using Warm Modifiers. Artists may add a few drops of warm modifiers or select warm-toned pigments to counteract the potential for ashy or overly cool outcomes.
Preventive Approach. This strategy is a buffer against the cooling effect, ensuring the pigment maintains the desired tone once fully integrated into the skin.

Selection of Pigments

Client's Skin Undertone. Consider the client's skin undertone when choosing pigments. Cool pigments on cool skin can intensify the Natural Cooling effect, leading to an undesirably cool result.
Pigment Temperature. The temperature of the chosen pigment (warm or cool) also plays a significant role in the final healed appearance.
Combination of Factors. The final healed result is a blend of the client's skin undertone, the temperature of the pigment used, and the natural cooling effect post-healing.

For permanent makeup artists, understanding and anticipating the Tyndall Effect and Natural Cooling is essential. These factors significantly influence the final appearance of the makeup. Choosing the right pigments, considering the skin's undertones, and preemptively adjusting pigment choices can ensure that the healed results align closely with the desired outcome.

14. Mixing pigments of different makers

In the world of semi-permanent makeup, the debate over mixing pigments from different manufacturers is common. While many pigment producers and brand-affiliated artists caution against this practice, the reality is more nuanced. The decision to mix pigments from different sources often boils down to understanding their chemical properties and colorant origins. As experienced artists point out, pigment molecules and elemental atoms are indifferent to brand labels.

Combining Organic and Inorganic Pigments

Blending organic and inorganic pigments is feasible, but it requires an awareness of their compatibility and stability. These pigments have distinct chemical compositions, and mixing them can yield unpredictable results. For instance, merging inorganic mineral colors with Carbon Black (or Black 2) can lead to unstable mixtures.

The Role of Additives

Understanding the additives in pigments is crucial for successful blending. It's essential to ensure that the chemical elements of the pigments' carriers are compatible. If one pigment primarily contains glycerin and alcohol as additives, mixing it with another pigment that shares these primary additives is advisable. This precaution helps avoid unexpected chemical reactions that could compromise the pigment's stability.

Particle Size Considerations

When mixing pigments, consider the size of their particles. Combining pigments with vastly different particle sizes is generally not recommended. Significant differences in micronization levels can disrupt even pigment distribution, affecting application and healing. Researching the micronization of pigments helps ascertain whether certain combinations are practical.

Practical Experience in Pigment Mixing

Experienced artists suggest using pure colors for greater control over the resulting shade. Mixing different shades of brow pigments can inadvertently produce gray tones that darken over time. Thus, selecting pure initial pigments is crucial.

Artists often experiment with blending different brands, including organic and inorganic pigments. The key to success lies in testing the stability of these custom mixes. For instance, immersing the blend in water can reveal its stability. However, furnace black or CI 77266, known for its furnacing method, can be challenging to integrate into mixes, often leading to unstable combinations. Conversely, other pigment blends are more stable, offering more versatility.

The Importance of Real-Life Testing

Ultimately, the most critical factor is how a pigment mix heals in a client's skin. Despite the marketing claims surrounding pigment mixing, real-world healing results are the true indicators of a blend's success. Experienced artists emphasize the importance of observing the healed outcomes in actual clients to gauge the effectiveness of pigment mixes. Real-life observations provide the most accurate assessment of pigment blending.

15. Conclusions

Mixing pigments for Powder Brows and Hairstrokes is a complex process that requires an understanding of color theory and pigment chemistry. Artists must consider a range of factors to achieve the desired results.

Color Theory and Pigment Chemistry

Color theory plays a crucial role in selecting and neutralizing pigments. Understanding primary, secondary, and tertiary colors and their complementary counterparts helps achieve the desired brow color. For example, salmon pink eyebrows can be neutralized with olive green, while cool gray eyebrows can be balanced with orange.

Chemistry is also key, especially regarding the main colorants used in pigments: Red, Yellow, and Black. These can be either organic or inorganic, each with distinct characteristics. By understanding the ratios of these colorants, artists can create a wide range of shades.
