Embarking on a hair color journey can be an exciting yet daunting task, especially with the vast array of shades and numbers to choose from. This comprehensive guide will demystify the hair color number system, helping you make an informed decision that's perfect for you.
Understanding the Hair Color Number System
The hair color number system is a universal coding used by hair professionals to identify specific shades. It was developed by the International Hair Color Chart (IHCC) to standardize hair color terminology. The system uses a combination of numbers and letters to denote the level of darkness, tone, and underlying warmth of a color.
Breakdown of Hair Color Numbers
Hair color numbers are typically represented as a three-digit code, with each digit serving a specific purpose:

- First digit (1-10): Represents the level of darkness or lightness. Lower numbers indicate lighter shades, while higher numbers indicate darker shades.
- Second digit (0-9): Represents the tone or underlying warmth of the color. Even numbers indicate cool tones (ash, platinum, blue-based), while odd numbers indicate warm tones (golden, copper, red-based).
- Third digit (0-9): Represents the intensity or vibrancy of the color. Lower numbers indicate more natural or subtle shades, while higher numbers indicate more vibrant or intense shades.
