[Hair transplantation in wound healing and scar repair in special areas].

To review recent advances in the application of hair transplantation in wound healing and scar repair in special areas. An extensive review of the literature on the application of hair transplantation in wound healing and scar repair in special areas was conducted, focusing on cellular functions, molecular mechanisms, and clinical applications. Hair transplantation has been shown to effectively promote wound healing and scar repair in special areas. The underlying mechanisms are complex, but current understanding emphasizes a strong association with hair follicle-associated stem cells (including epidermal stem cells, dermal papilla cells, dermal sheath cells, etc). The application of hair transplantation in wound healing and scar repair in special areas remains in its early stages. Further investigation into its mechanisms of action is essential, and randomized controlled trials are needed to establish its efficacy.
