Description: The Cosmetic Republic's hair fibers are made of natural vegetal origins. They adhere to hair better than most as they carry a negative charge and our hair carries a positive charge. Unlike wool and other materials, the potential for scalp irritation is low as the keratin fibers bond to the hair instead of repelling it. The fibers are also non-dyed, giving it a more natural look. The lightweight hair fibers also spread evenly over hair.
