A hair transplant is a minimally invasive to surgical procedure in which hair follicles — individually or in strip form — are harvested from a donor area (typically the back or sides of the scalp, which are genetically resistant to DHT-induced hair loss) and implanted into bald or thinning areas of the scalp.
The procedure is considered the gold standard for permanent hair loss treatment in cases of androgenetic alopecia (male or female pattern baldness), traction alopecia, burn-related hair loss, and hairline reconstruction after trauma or surgery.
Results are permanent because donor follicles retain their genetic resistance to dihydrotestosterone (DHT) even after transplantation — meaning the transplanted hair continues to grow naturally for life with proper care.
