Hair Loss Surgery
During hair transplantation, the dermatologist removes a small "punch" of skin with full hair thickness from one part of the body (usually the back or side of the scalp) and transplants it into a bald patch. Several surgeries are usually performed over a few months.
Hair transplantation is expensive, time consuming, and sometimes painful. A very small percentage of patients suffer chronic head pain afterward. Potential complications include permanent scarring and chronic infection.
Scalp reduction involves reducing the size of the scalp. The doctor stretches the skin on the top of the head and cuts some of it away, thereby reducing the total area of bald skin. In a procedure known as a "flap," the doctor stretches a piece of skin that has hair on it and folds it over the bald area. Scalp reduction is often combined with hair transplantation.
