Review (1/5): I threw it away - just glides on top of hair
This does not penetrate my hair, just glided on top. I don't even have thick hair or a lot of hair. It's pretty fine and medium thickness and straight. Even if I held my hair taught it wouldn't penetrate. I threw it away because I didn't try to use it til after a month was up - it went it my travel kit. I was never able to get the stickiness of the label off either.
