Wow! I didn't know that I actually needed this tool. It's so soft and works really well on my scalp. My hair does not fall as much during shampoo, and cleans my hair & scalp without hurting me. I've always been vigorous when I shampoo and I have the bad habit of using my nails, i.e. causing scratches on my scalp. Been using this for several weeks now and my scalp loves it.
