Review (5/5): Useful
Purchased for my preteen boys because they never really get to their scalp when washing their hair. Worked perfectly for them.
My only issue is it had a sort of smell like conditioner/shampoo on the back & a smeared spot between the spikes leaving me to believe I may have received a used item. No way to really be sure so I just cleaned it before use.
I can still recommend the product, but maybe just clean it first.
