Understanding Your Hair Color Number

If you have ever looked at hair dye boxes or consulted with a colorist at a salon, you may have noticed that hair colors have specific numbers or number-letter combinations. These numbers are not arbitrary; they are part of an international color code that helps standardize hair colors across different brands and salons. Understanding these can help you better choose and communicate your hair color preferences.

Decoding the Hair Color Number System

The hair color numbering system divides hair color into levels, typically from 1 to 10 (sometimes up to 12 in professional brands), and tones. The levels correspond to how light or dark the hair is while the tones denote the hue or shade.

• Levels
  • 1 - Black
  • 2 - Darkest Brown
  • 3 - Dark Brown
  • 4 - Medium Brown
  • 5 - Light Brown
  • 6 - Dark Blonde
  • 7 - Medium Blonde
  • 8 - Light Blonde
  • 9 - Very Light Blonde
  • 10 - Lightest Blonde
  • 11-12 (Specialty products) - Ultra Light Blonde

Tonal numbers or letters represent the hair color’s underlying tones. Common tones include Natural (N), Ash (A), Golden (G), Copper (C), Red (R), and Mahogany (M). Neutral tone is marked as 0 and it does not modify the base color.

For example, a hair color with the number 6G denotes a dark blonde with golden undertones. If it is 5C, it indicates a light brown with copper hues.

Choosing the Right Color

Understanding the numbering system not only helps you decode what each number and letter represents but also assists you in choosing the perfect shade. When selecting a hair color:

1. Determine your natural level: Look at the roots of your hair to understand its natural level. Choose a color that complements or is close to this level for the most natural results.
2. Consider the desired tone: Pick a tone that matches your skin tone and the look you are aiming for. Golden tones complement warmer skin tones, while ash tones suit cooler skin tones.
3. Consult with a professional: Especially if you are making a significant change, it's advisable to consult with a professional hairstylist or colorist. They can provide personalized advice and ensure that the color application is professionally done.

Conclusion

The hair color number system is a fundamental tool that helps both stylists and clients in achieving the desired hair color. Whether you're dying your hair at home or in a salon, a basic understanding of this system can lead to better outcomes and more satisfying color choices. Remember to always conduct an allergy patch test before applying a new hair color.

Lastly, hair color can be more than a number and tone; it’s about expression and confidence. Choose what feels right for you and enjoy your new look!
