The slicker brush is designed with long, tightly packed stainless-steel bristles that can penetrate deep into the undercoat to remove matted hair. Each wire bristle is angled slightly as to not scratch the skin. Regular brushing helps to re-distribute natural oils through the coat to keep it healthy and shiny. It can also help to reduce shedding and knots. The Wahl Slicker brush is suitable for medium to long coat.
