As for upcoming advances, one technique doctors have high hopes for in the future is hair cloning. Currently being researched by a handful of companies, the process is many years from hitting the market. Bosley is looking to make it work by extracting cells from the areas of a man’s head that resist balding, putting them in a lab dish and multiplying them by the thousands. The hope is that once the new cells are injected back into the scalp, they’ll work with skin cells to form new follicles, says Dr. Ken Washenik, medical director of Bosley. Unlike with transplants, the patient could end up with more hairs overall.
