Review (1/5): Didn't work well on my thick hair
I have thick mediterranean curly hair. This comb was great in theory in that the longer length of the teeth reach closer to the scalp and can make for much straighter hair; however, the flimsy plastic and the supposedly ceramic teeth made it difficult to not pull my hair out.
I'd say the design idea is excellent: longer thinner teeth make for a better straight, but the cheap material this comb was made with made it worse to work with. The description says this is anti-scald, but it gets quite hot on the hand and scalp.
Also, my heat protectant spray got clumped up in little bits between the teeth. This doesn't happen with my other hair straightening comb. This is for people with mildy wavy hair. If you have thick, tangly type of hair, you may be wasting your money by buying this.
