GLOSS FOR ALL HAIR COLORS: Add brilliant shine to your hair with Madison Reed Color Reviving Gloss in Glassa. Madison Reed Color Reviving Gloss in Glassa can be used on all hair types and colors for the ultimate refresh—clear, glossy shine and a sleek finish. Shine-boosting formula absorbs into the hair cortex without putting it through a chemical change, unlike permanent alkali color, which opens your hair shaft to remove natural pigment + deposit color. Because of this difference, our gloss does not cover grays. Each gloss includes 1 pair of gloves, contains 1-2 applications (depending on hair length/thickness) and lasts 6-8 shampoos. Infused with hair-loving keratin, argan oil and ginseng root extract, our colorless hair gloss keeps your hair soft + shiny
