To find out why you have hair loss, you may also need a blood test. This can check for things going on in your body that may be causing your hair loss. Some patients need a procedure called a scalp biopsy. Your dermatologist can quickly and easily take what is needed for the scalp biopsy during the consultation. If the exam and tests show that you are a good candidate for a hair transplant, your dermatologist can tell you what results you can expect. A full head of hair may be unrealistic, but a fuller head of hair can be the goal. Most patients remain awake during the entire surgery and need only an anesthesia that makes the scalp numb. Some patients also take a mild sedative to help them relax. The surgery begins with your dermatologist removing the healthy hairs. To give you natural-looking results, your dermatologist may remove the healthy hairs by either cutting a strip of skin with healthy hairs from your scalp or removing individual hairs.
