BosVolumize Hair Thickening Fibers provide instant thicker fuller-looking hair.

BosVolumize Hair Thickening Fibers naturally bond to existing hair with keratin fibers that blend and cover thinning and low-density areas. Because our own hair is made of Keratin and naturally holds a positive charge, BosleyMD Hair Thickening Fibers are designed to mimic our own human hair but with a negative charge. Therefore, when negatively-charged, lightweight, easily blended BosleyMD Fibers come in contact with our positively-charged hair, it creates a static-cling effect, naturally binding to the hair shaft creating instantly thicker, fuller-looking hair.
