REFRESH Dry Shampoo is a waterless formula that is quicker and more convenient than traditional hair washing. It's ideal for traveling, camping, playing sports, or when going to and from a variety of places (gym, office, school, hospital, etc.). REFRESH can even be used on wigs and extensions! To use, spray REFRESH directly onto the hair at a distance of 12 inches . Massage into the scalp to penetrate the hair shaft (this absorbs excess dirt, oil, and product build-up), then simply brush out and style hair normally.
