I have owned this comb for over 2 years but never really used it, I bought it to help flat ironing my hair but somehow found it useless. I am not exactly sure of the brand, that's why I put it in "Unlisted", all I know is that it's gray, made of plastic, and it says "Ceramic Tools" on one of the sides. One side is a fine tooth comb, the other has a slit that fits the teeth. It actually is shaped like a flat iron, in the sense that it has a spring where the 2 sides meet and you operate it as you would a flat iron.
It was only recently that I discovered what a gem this inexpensive utensil really is. I realized that one of the reasons I was getting breakage while flat ironing was because I was going through a (thicker) strand of hair 2-3 times to achieve that stick straight look. I also remembered that all stylists use a comb when they flat iron your hair, but there was no way for me to iron using a regular comb at the same time. So I dug out this comb and tried to mimic what they do at the salon. YESSSS! Now I could not be without this comb! My hair comes out better than at the salon, and the damage from ironing is minimized, because I only need one pass with the flat iron and my hair gets stick straight, silky and shiny, and stays that way until I wash it again.
Just make sure to take very thin strands of hair at one time, comb through with a regular comb first to make sure there are no tangles, then put this comb at the root and start slowly going down the strand, following closely with your flat iron. Perfect results guaranteed every time :D
