Selecting the appropriate material is critical for performance and scalp health. For detangling, look for flexible nylon bristles or TPE (Thermoplastic Elastomer) pins. For smoothing and shine, 100% natural boar bristles are the industry standard as they distribute natural scalp oils. For heat styling, prioritize ceramic-coated barrels or carbon fiber materials that can withstand temperatures up to 230°C (450°F) without warping. If targeting the eco-friendly market, source brushes made from biodegradable wheat straw, bamboo, or FSC-certified wood.
