The Roots Brown Combs include cellulose (an extract from plants) acetate, which reduces static and reduces frizz and flyaways. These combs are also hypoallergenic thanks to the material, which means that they are skin-friendly and won't irritate any skin types. The combs also include smoothened tooth edges to prevent scratching the hair cuticles and scalp whether styling dry or wet hair, as well as smoothened and rounded tips that massage the scalp and promote the natural oils. Watch how the hair acts and maintains its position as you have a soothing and pain-free combing experience.
