I was so excited when I ordered this product. I have straight hair, but still put effort into blow drying it piece by piece with a big round brush to make sure it looks smooth. I though this comb would do just that, plus lessen the volume that a round brush adds, making it sleeker looking. That did not occur. I have a bob, just below my chin, but I could not get the comb through my hair, even if I brushed it first. My guess is that my hair is too thick for this comb.
