The brush has an outer layer of fixed pin tufts which encircle the exterior of the brush pad and preferably are metal pin tufts. The brush has a middle layer of flexible tufts preferably made of pure boar bristles and which are surrounded by the fixed pin tufts. As the brush is moved through a pet's hair or human hair, the outer layer of fixed pin tufts gently yet thoroughly detangles the coat, removes larger particles and provides a gentle massage effect, then the middle layer of pure boar bristles conditions the hair by distributing natural oils, leaving a healthy shine and a protective layer over the pet's coat, and then the opposite section of fixed pin tufts passes through the hair once again to smooth and separate the conditioned hair. ## Claims ### Claim 1 A hair brush consisting of: a. a support base which retains a brush pad which has a center area and an exterior circumference adjacent the support base;
