Changing existing hair color takes a degree of know how. Each stylist has to know their products, or know where and how they can find the information on how to use the product.
There are some colors that are temporary, lasting only shampoo to shampoo, that includes no chemicals. These are known as nonoxidative colors, that is they are not mixed with developer, which means there is no chemical reaction. Developers are an oxidizing agent, usually Hydrogen peroxide. This is ideal for guest’s that want a quick touch up without having to come into the salon.
Most colors done in salon are oxidative colors. They are long lasting semi-permanent (demi-permanent), permanent, toners, and fillers. These are colors mixed with developer to create a chemical change that usually has a longer effect on the hair. This includes either deposit (darkening) or lifting (lightening) of the hair.
Lighteners are a type of bleach, that are also used with developer, on or off the scalp, to create a chemical change in the hair. This is a permanent change to the hair. The process eliminates the melanin in the hair strand.
Other Color Products: vegetable, metallic, and compound dyes (both vegetable and metallic dyes combined).
