This hairbrush is absolutely FANTASTIC! I purchased mine from Planet Beauty in Santa Barbara, and I wish I had bought two of them. The concave shape is almost like a gentle hand cupping your head, it feels SO nice! Super relaxing, almost like a scalp massage, and it doesn’t pull my hair at all. I have very fine hair, and I get less breakage using this brush. I absolutely love it and I can’t recommend it enough for my hair type!
