Linear scar formation in the scalp after suturing an incision has been considered unavoidable. It was not known why scars formed even if the hair bulb was left intact. The authors developed a subcutaneous tissue-shaving method for radical treatment of bromidrosis and studied the process of hair regeneration by using thick-tissue specimens. They suggest that stem cells (lower) are located not only in the lower end of the telogen hair follicles but also in the sebaceous isthmus at the secretory opening of the sebaceous gland (upper stem cells). They found that linear scars can be prevented and existing linear scars can be surgically treated by using a relaxed suture on a scalp incision to avoid excessive pressure on the upper stem cells.
头皮切口缝合后形成线性瘢痕一直被认为是不可避免的。即使毛囊球保持完整，瘢痕为何仍会形成尚不清楚。作者开发了一种用于根治腋臭的皮下组织刮除方法，并通过使用厚组织标本研究了毛发再生过程。他们认为干细胞（下部）不仅位于休止期毛囊的下端，还位于皮脂腺分泌开口处的皮脂腺峡部（上部干细胞）。他们发现，通过在头皮切口上使用松弛缝合以避免对上干细胞施加过大压力，可以预防线性瘢痕，并且现有的线性瘢痕可以通过手术治疗。
