Developers (Hydrogen Peroxide) are responsible for both lightening and deposit. The amount of lightening listed below is approximate and is affected by both, the texture of the hair and the natural color of the hair.
There are 4 Chromastics developers 10, 20, 25, 40
10-Volume for less lightening, for use with Deposit-Only and for use with Liquid Shades
20-Volume for standard lightening
25-Volume for resistant or coarser textured hair
40-Volume for extra lightening
30-Volume is created by mixing equal parts of 20-Volume and 40-Volume. All Chromastics colors and lighteners are mixed in a one-to-one ratio with developer.
