    TLDR New suturing technique with wider intervals and shallow stitches helps prevent scalp scars and promotes hair growth.
    In 1995, Yoshikata Inaba, M.D., and Masumi Inaba, M.D., presented a study on the prevention and treatment of linear scar formation in the scalp, suggesting that stem cells responsible for hair regeneration are located in the sebaceous isthmus. They proposed that conventional suturing methods can damage these stem cells, leading to hair loss and scar formation. The study recommended a new suturing technique that involves relaxed suturing with wider intervals and shallow epidermal suturing to prevent damage to the sebaceous gland. This method was found to be effective in preventing linear scar formation and promoting hair regeneration without leaving visible scars. The authors also introduced a hypothesis that the center of hair regeneration is at the sebaceous isthmus and emphasized the importance of avoiding tension during suturing to successfully correct scars.
