I ended up buying a second one
I got one of these for myself a few months ago because I read they can help with scalp itch. I don't have dandruff, but I do have dry scalp (thanks Winter) and some irritation due to using dry shampoo. Admittedly it felt weird to use at first, but after just the first use, my scalp was itching less (after I added the use of an apple cider vinegar clarifying shampoo, the itchy scalp is GONE). It has made a noticeable difference in terms of scalp itch and how clean my hair looks and feels. I was excited and told my husband about my triumph over itchy scalp and the next thing I know, he has started using my shampoo brush (even though he made fun of me for using it in the first place)! He has some dandruff but doesn't have the itchy scalp. I'm not sure if it has helped him or not but he must enjoy using the brush because he keeps using mine. This is the exact reason I have now bought a second one. We both enjoy using it.
