Advanced Gray Solutions Semi Permanent Hair Color
Clairol Professional Beautiful Collection Advanced Gray Solution Semi-Permanent hair color has no ammonia, no peroxide and is gentle enough to be used right after relaxing. With Advanced O2 Technology, this hair color provides intense gray coverage and works as a refresher for permanent hair color by adding luster to dull-looking hair. Advanced O2 Technology uses oxygen in the air to develop the color vs. heat or hydrogen peroxide. The end result is shiny, moisturized color with gray coverage that lasts up to 12 shampoos.
