One fact about hair transplants is that the doctor often performs the procedure in his office using local anesthesia, states WebMD. Another fact is that U.S. doctors have been performing hair transplants since the 1950s.
To perform a hair transplant, the doctor must remove a narrow area of hair-bearing scalp from the back of the head. The doctor then uses this same piece of scalp to cover an area with no hair or very thin hair, explains WebMD.
Due to the invasive nature of the procedure, the patient may have a sore scalp for the days following the hair transplant, states WebMD. Doctors may prescribe an antibiotic or anti-inflammatory medication. In most cases, patients return to work two to five days after surgery.
Transplanted hair usually falls out two to three weeks after surgery; however, the transplant produces new growth, usually within a few months, according to WebMD. The majority of the patients see a 60 percent increase in new hair growth in the six to nine months following the hair transplant.
Although hair transplants are common procedures, patients run the risk of infection, states WebMD. The procedure can also leave scars or other complications, such as unnatural-looking hair growth or folliculitis. Folliculitis is an inflammation of the hair follicles that can occur as new hair begins growing after the transplant.
