Gloss treatments won’t give you the glossy dream hair you see in commercials, but it does come pretty close, especially for brunettes and redheads, because darker shades reflect light better than fair ones. As the stylist saturates the wet hair with the gloss and then allows it to heat under the dryer, the heat opens the hair cuticle, the gel soaks in, and the shine is locked into hair creating a seal around the shaft of your hair.  Unlike pomades and shine sprays, it doesn't’t make hair look greasy. The glossing lasts up to 6 weeks, depending on hair-color, styling routine, how often you shampoo and what shampoo and conditioner you use?
