Scalp Protector is your go if you have sensitive skin or you want just a few more days of hold time. Scalp Protector forms a protective barrier to prevent irritation from adhesives. It also improves adhesion, and duration of bonds. Works great in hot and humid weather conditions. Great if you play sports or have oily skin. It may also be applied to hair systems to improve cleanup. Finally, Scalp Protector lets you get an extremely strong bond right away without the normal 24 hour wait. Pretty amazing stuff. If you are not wearing it….why? This is a must have for summer at least.
