Here's a link to it. They offer money back guarantee with all of their products. I've been emailing a rep and they seem pretty confident in their products but i always take that with a grain of salt. They also offer a white glue called Pro Bond 3 and a scalp protector that's supposed to be designed for people with oily skin and sweat. I'm likely going to try a few of their products and see how they work.
