Love It!

I had gotten my hair caught in a drill a few years back. As you can imagine, it took quite a good chunk from the front of my head (hairline to behind and around the temple area). I'vetried home remedies, (cornstarch/charcoal/colored dry shampoo/etc) and nothing would work. Stumbled across thisproduct while ordering some hairspray and let me tell you it is AMAZING!!!!! Very simple to pat on, sweating and humidity did not effect it, (I was worried there would be black powder dripping from my head while I'm working and me not realize) and it doesn't leave any type of annoying or weird feel to it. Love, love, love this product!

Hair filler

This product helps to hide my bald spots making my hair look thicker and healthier. It is easy to use and sprinkles out generously to fill in thin hair.

This product works great! I use it to cover up a cowlick, and it stays on.
