Kemon NaYo Color System Permanent Hair Color:

Kemon NA YO Permanent Color System 2 Ounce 60 Milliliters is designed to cover gray hair (100 % coverage) and deliver vibrant, intense color on pre-lightened or virgin bases. The shade system is intermixable, meaning shades within NaYo can be blended or diluted (e.g. combining neutrals, fashion tones) to create customized hues. The absence of ammonia and fragrance is meant to reduce irritation, odor, and harshness. The presence of botanical extracts helps support a more comfortable coloring experience. With the right developer (activator) and using “super‑lightener” techniques, it’s possible to lighten 4–5 levels while still maintaining color consistency.

Typically, NaYo color cream is mixed with NaYo Cream Activator (developer) in a ratio (for most shades) of 1 : 1.5 (color : activator) For super-lightening shades, the ratio can go to 1 : 2 (i.e. more developer) to enhance lifting power. Using the appropriate volume of developer (10 vol, 20 vol, 30 vol, etc.) is crucial to control lift and deposit. (Product text mentions use of 10, 20, 30, 40 volumes in combinations)
