The Kent Pocket Comb is coarse toothed, which is ideal for thick hair. Its small size makes this comb perfect for grooming on the go. The soft, rounded teeth of Kent combs are designed to not damage your hair or scalp. Each comb is made from cellulose acetate, a non-petroleum based plastic derived from plants. This material is tactile, flexible, and strong. These smooth teeth stimulate the natural oils inside the hair cuticles as your hair is combed, which helps to naturally create strong, healthy, shiny hair.
