Tan Mujiang's patented tooth-shaping technology has been carefully crafted to enhance the comb's durability and combing experience. After extensive testing, we've successfully crafted this practical comb. The back of the tooth-shaping comb is made from 100% natural wood, along the grain, for exceptional strength and resistance to breakage. Each tooth-shaping comb undergoes over 20 production steps to effectively detangle and detangle hair. It removes tangles and loose hair, preventing knots and tangles that ultimately lead to breakage. It also gently stimulates blood circulation, effortlessly combing each strand.
