Review (4/5): A bit too soft
I personally find these a bit too soft. They're not meant for scrubbing the scalp. What I find myself doing is rubbing my scalp with my fingers then using this brush afterwards. It gently breaks up shampoo buildup and helps with dandruff and itchy scalp. It's easy to hold and the size is big enough that I can rub a quarter of my scalp at a time. I bought another shampoo brush previously. The bristles were much harder and hair would get caught in it and be nearly impossible to clean. Plus it never did that great a job at cleaning my scalp.
Also, this one is also a good bargain with two in a pack.
