Redken's Gloss-In-Mask combines the shine effect of a professional gloss with the moisturizing care of a mask. The silicone-free formula is based on an innovative cream-to-gloss technology that provides intense shine and long-lasting moisture to the hair. The ultra-acidic pH value of the mask removes residue on the hair surface and aligns the hair fibers so that they reflect more light - for visibly shinier hair. The glycerin in combination with fatty compounds provide the hair with 4x more moisture without weighing it down. For maximum shine, moisturized and healthy-looking hair. Application: Shake tube well before use. Apply to cleansed, wet hair from lengths to ends. Leave on for 1 minute. Then rinse thoroughly with water. Weekly use is recommended in combination with the entire Acidic Color Gloss System. Can be used as often as required. Warning: Avoid contact with eyes. In case of contact with eyes, rinse immediately and thoroughly with water.
