Because XFusion's colored organic fibers are made of pure keratin protein - the same protein that makes up human hair - it offers a completely natural solution to thinning hair. In a matter of seconds, hair looks significantly thicker and fuller, and scalp show-through disappears. And XFusion lasts all day, through perspiration, wind and rain, as only shampoo will remove its magnetized protein fibers. Simply shake XFusion into any area of thinning hair. The organic keratin fibers instantly cling to and fill out existing hair.
