Hair ServicesQuestion 431 of 484
The 'tone' designation on a hair color label (for example, 6N, 6G, 6A) tells the stylist:
a.The viscosity of the cream base
b.The recommended processing time only
c.The dominant reflective hue at that level, such as Natural, Gold, or Ash, allowing the colorist to predict warmth or coolness and to choose corrective tones using the color wheel
d.Whether the formula contains ammonia
Explanation
Hair color is specified as a level (1 to 10 from darkest to lightest) and a tone (the reflective hue at that level, such as N for natural, G for gold, A for ash, R for red, V for violet). The tone tells the colorist whether the formula will pull warm or cool and is used together with the color wheel to neutralize unwanted tones (for example, a violet-based toner neutralizes yellow). Viscosity, processing time, and ammonia content are formulation properties not encoded in the level-and-tone label. California licensees apply oxidative color under CCR Title 16 §979.4.
