Meant only for very thick and full hair.
For what this comb is supposed to do, blend in colors, products, etc. with fine or thinner hair it is just another comb. It does not do as advertised and if I'd not waited months until my next color melt then I'd send it back. Too late for a return now,  but i do believe this will work well with thick hair. In any case it is the same as the WOW comb, just a tad cheaper. I'm not sure what to rate it because it wont work for me, but i think they should warn customers that it will not blend fine hair.
