In hair dye, the number "0" often indicates a natural (neutral) undertone.
Understanding Hair Dye Numbering Systems
Hair dye colors are usually represented by a combination of numbers and sometimes letters. These codes provide information about the depth (lightness or darkness) and the tone (or undertone) of the color. The first digit typically represents the level or darkness of the hair color, while the digits after the decimal point represent the tone.
How the Number "0" Works in Hair Dye
According to the reference information, the second digit in many hair dye systems signifies the color's tone. Here's a breakdown:
| Digit | Tone |
|---|---|
| 0 | Natural (Neutral) |
| 1 | Ash (Cool) |
Specifically, "0" means that the color has a neutral undertone, lacking strong warm or cool tones. This results in a more balanced and natural-looking hair color.
Practical Insights:
- Natural-Looking Results: If you aim for a natural hair color that isn't overly warm or cool, selecting a dye with "0" as the tone indicator can be a good choice.
- Blending: Natural tones often blend well with most skin tones, making them versatile.
- Base Color: Using a neutral-toned color with a "0" can serve as a base to which you may add a second colour, to customize your hair colour result.
Example:
- 5.0: This would indicate a medium brown color with a neutral undertone.
- 7.0: This would indicate a medium blonde color with a neutral undertone.
By understanding these numbering systems, you can make more informed decisions when choosing a hair dye. The "0" designation plays a vital role in achieving a neutral and balanced hair color.
