Hair transplantation involves hand-implanting individual hair strands into the doll's scalp, rather than using a removable wig. This technique creates a more natural and realistic appearance, especially when parting or styling the hair.
The main advantages of hair transplantation include a realistic appearance, resistance to slippage, versatility in styling, and a pleasant feel. Hair transplantation is typically made from real human hair.
Hair transplantation is often used on dolls with silicone heads because this material holds the hair in place better than TPE (thermoplastic elastomer).
