Crafted with a combination of both boar bristles and nylon pins, bradford pin bristle brush polishes and smooths all hair types. boar bristles help maintain the health and condition of hair by carrying sebum from the scalp to the end of the hair shaft, coating each hair strand with natural oils. this helps to repair dry hair and add shine. the nylon pins penetrate deeply, helping to detangle and smooth your hair. all Evo hair brushes and combs are manufactured with an environmental conscience. each brush is made with fsc® certified wood from well-managed forests.
