Exclusive Go Green Treatment Comb: Meet the Wet Brush Go Green Charcoal Infused Treatment Comb that gently separates knots and snags. Ordinary combs rip through and pull out the knotted hair instead of gently separating it. But these brushes use the exclusive WaveTooth design to evenly distribute hair across teeth for effortless detangling. Featured in 3 treatments: Charcoal, Coconut Oil, and Tea Tree Oil.
