TLDR Removing the outer layer of skin cells from hair grafts does not change the graft survival rate but may improve how it looks right after surgery.
The study "Effect of De-epithelialization on Graft Survival Rate After Follicular Unit Extraction" involved 64 male patients with androgenetic alopecia. The patients were divided into two groups: one underwent de-epithelialization and the other served as a control. The study found no significant difference in hair shaft elongation and the percentage of anagen hair follicles between the two groups. The immediate postoperative satisfaction was higher in the de-epithelialization group (100%) compared to the control group (71.25%). There were no significant differences in shedding rate, graft survival rate, and complications between the two groups. The study concluded that follicular de-epithelialization does not affect the survival rate of the graft in Follicular Unit Extraction (FUE), but it may improve immediate postoperative appearance and lead to a more pleasing cosmetic outcome.
