Redken's Gloss-In-Mask combines the shine effect of a professional glossing treatment with the moisturizing care of a mask. The silicone-free formula is based on innovative Cream-To-Gloss technology, which provides intense shine and long-lasting hydration for the hair. The ultra-acidic pH of the mask removes residues from the hair surface and aligns the hair fibers to reflect more light - resulting in visibly shinier hair. The included glycerin, combined with fatty compounds, delivers four times more moisture to the hair without weighing it down. For maximally shiny, hydrated, and healthy-looking hair.
