The Hair Wizard’s™ wire teeth separate every last hair strand. It actually reaches under the hair, down to the hide and pulls up that hair you didn’t even know existed. This is not possible with any other comb. The Hair Wizard™ is very beneficial in the loin to tailhead and top area, the flank and belly line, and the back fins of legs. . The Hair Wizard come in 6″ and 9″ combs. Every comb is now sold with a plastic case to protect the teeth.
