Color chemicals leave hair porous and vulnerable to humidity. Dreaded moisture gets in - hair gets puffy, frizzes out! DREAM COAT, inspired by new textile technology, covers each hair strand with an invisible waterproofing cloak. Heat-activated polymer works to compress, tighten and seal hair strands. Hair is supernaturally-sleek, smooth and super-silky. Unlike typical "humidity-guard" serums, Dream Coat will not build up, weigh hair down or make it greasy. Effects last up to 2 to 3 shampoos.
