Review title is They actually Work! [SEP] Before buying these, I typically used a comb to pull loose hair from my brush. Although it worked, it was hard on the bristles in the brush head. It would lead to broken bristles or completely pulled them out. I bought these with a considerable amount of doubt but after using them I realized that in fact, they do work and don't damage the brush head. Simply rake the tool through your brush and pull the hair from the tool. That's it. Keeps your brush hair free and much cleaner than you would think.
