Here's a breakdown of how natural hair pigments influence color selection:
1. Types of Melanin:
* Eumelanin: This is responsible for dark brown and black hair. The more eumelanin present, the darker the hair. Different types of eumelanin molecules dictate brown versus black shades.
* Pheomelanin: This is responsible for red and blonde hair. It produces yellow and red pigments. Individuals with predominantly pheomelanin have red or blonde hair.
* Both: Most people have a combination of eumelanin and pheomelanin. The ratio between the two determines the resulting hair color.
2. Hair Color Levels:
Hair colorists use a numbering system (usually 1-10, but sometimes 1-12) to describe the lightness or darkness of hair, with 1 being black and 10 (or 12) being the lightest blonde. Your natural hair level significantly impacts the outcome of any hair coloring process.
* Darker Levels (1-5): Starting with dark hair requires more lifting (bleaching) to achieve lighter shades. This can lead to more warmth (red/orange tones) being revealed during the lifting process.
* Lighter Levels (6-10): Lighter hair lifts more easily and is less prone to pulling strong warm tones. Achieving lighter, brighter colors is generally easier.
3. Understanding Undertones:
Natural hair, even seemingly "neutral" brown or blonde, has underlying warm or cool tones. These undertones become more apparent during the coloring process.
* Warm Undertones: These include red, orange, and gold. Dark hair often has warm undertones that can be difficult to neutralize.
* Cool Undertones: These include blue, green, and violet. Lighter hair can sometimes have cool undertones, which can make it difficult to achieve super-warm shades.
* Neutral Undertones: These are less dominant warm or cool tones.
4. How Pigment Influences Color Selection:
* Color Theory: Color theory is essential. Understanding the color wheel helps you choose colors that complement or neutralize existing undertones. For example:
* Counteracting Brassiness: If you're lifting dark hair and getting brassy (orange) tones, a toner with blue or purple pigments can help neutralize the unwanted warmth.
* Enhancing Warmth: If you want to enhance the natural warmth in your hair, choose colors with golden or copper tones.
* Lifting Requirements: The amount of lift required to achieve a desired color depends on your natural pigment. Darker hair needs more lifting, which can cause more damage. Consider if the desired color is realistically achievable without excessive damage.
* Color Deposit vs. Lift: Some hair colors only deposit pigment (like direct dyes), while others lift existing pigment and deposit new color (like permanent dyes). Your choice will depend on your natural color and the desired result. For example:
* If you have light blonde hair and want to go darker, you can often use a demi-permanent color that deposits pigment without lifting.
* If you have dark brown hair and want to go blonde, you'll need to use bleach to lift your natural pigment before depositing the blonde color.
* Gray Coverage: Gray hair lacks pigment. This makes it more resistant to color, and often requires specialized formulas to ensure proper coverage and longevity.
* Previous Color: Previous dyes or chemical treatments can affect how your hair reacts to new color. Hair that has been previously bleached or permed may be more porous and absorb color unevenly.
Practical Implications for Color Selection:
* Consult a Professional: A hair colorist can assess your natural hair level, undertones, and hair condition to recommend the most suitable colors and techniques. They can also predict how your hair will react to the coloring process and minimize damage.
* Strand Test: Before applying color all over your head, do a strand test on a hidden section of hair to see how the color takes and to assess any potential adverse reactions.
* Consider Your Undertones: Choose colors that complement your skin tone and eye color, and work with your natural undertones, rather than against them.
* Gradual Changes: If you're making a drastic change (e.g., going from dark brown to blonde), do it gradually to minimize damage and allow your hair time to adjust.
* Be Realistic: Understand that the color you see in a photo may not be achievable in one session, especially if you have dark hair.
* Maintenance: Choose a color that you're willing to maintain. Some colors require more frequent touch-ups than others.
* Use Color-Safe Products: Protect your color with sulfate-free shampoos and conditioners designed for colored hair.
In conclusion, understanding your natural hair pigments and how they interact with dye is crucial for successful and flattering hair color results. Consulting a professional colorist is always a good idea, especially for significant color changes. By considering your natural hair level, undertones, and desired outcome, you can achieve beautiful, healthy, and long-lasting color.
