Dermabrasion may lead to hair regeneration

Article-Dermabrasion may lead to hair regeneration

Philadelphia—A University of Pennsylvania research team studying wound-healing in mice has happened upon a discovery that may lead to a way to reverse hair loss in humans, reports HealthDay News.

During their study, the researchers noticed that study mice developed new hair follicles after their skin was scraped. The study’s authors note that this is rather unusual because the conventional wisdom has always been that an animal or human can develop no new hair follicles.

Though the discovery does not prove that new follicle growth occurs in wounded humans, the researchers say they are hopeful that it can be done—especially considering that current treatments for baldness do not create new follicles to replace those that have died.

The study’s authors write that something in the mice’s healing process apparently reprogrammed stem cells in the skin to start making new follicles, and that the new appeared to sprout hair. They speculated that perhaps future hair-growth treatment could be achieved through a form of dermabrasion, because the wounds that seemed to cause the hair regrowth in the mice were similar to the wounds caused by dermabrasion.

The study authors also note that their findings may lead to a way to treat burn victims by producing skin grafts that look and function like normal skin.

The study appears in the May 17 issue of the journal Nature.
