Scarring alopecias are definitive, whether they are of infectious, inflammatory, accidental or congenital origin. In fact, they are the result of a process that has caused the irreversible destruction of hair follicles. These follicles are replaced by a smooth, shiny, fibrous scar. The more extensive the scar, the more visible it is. Some patients wish to conceal it.

The CMCC offers two types of surgery to address this condition:
- hair transplants involves extracting hair follicles from the crown or temple to implant them on the scar. The implanted hair covers the scar and conceals it almost entirely.
- restorative surgery to remove the scar surgically. The goal is to make it more discreet than it was.
