Review (3/5): Works but with issues
As a wave builder, it does work. Tames the hair nicely when you continuously brush with it.
The only downside is that it sheds. A LOT. Which then get stuck in your hair. NO matter how much I rinse or try to avoid this, it's pointless. Which means I can't use it as much as I want, due to the bristles getting caught up in my not-at-all-this-color hair.
