Botox mask is designed to serve three purposes; strengthen, protect the hair and conserve the brightness of the hair. The cover is free of any sodium chloride and instead has silicones and vitamins that help to seal the hair cuticles and protect the hair fiber. In other words, Botox mask is an all-around package of restoring capabilities. We use it on many of our clients, and they appreciate the healing effect of the Botox mask.
