It glides through the hair easily, and when you brush and blow dry at the same time, it grabs onto the hair, separating it, so that it dries faster and the hair dries straighter. My Yorkie's hair(Violet) was extra shiny and straight. It also gets tangles out easier. I'm going to order the small one, (ringside) something like that, to get behind legs and under the chin. The aluminum combs are great too!
