Customer Review: "I like using this product as the directions say, but I also use it to gently massage my scalp when my hair is dry. I've tried a scalp brush before, one that has triangle-shaped bristles with a handle that semi-wraps around my hand, and I found that this one can really get into my fine yet dense head of hair. It's gentle, durable, and very comfortable to hold. I can tell that it's not missing any areas of my scalp because of the bristles' different lengths. It was a great purchase, in my opinion."

Customer Review: "Wanted a brush to help with my dandruff and itchy scalp. The bristles are softer than the ones I have found in stores which is nice, although I wish they were just slightly more firm. However, using it in the shower for shampooing hair is good [and] feels nice. I don't know if it is helping my scalp, but it does at least feel good."
