CAUTION:
Many doctors take up hair restoration because it is a low- risk, high-cost procedure - $3,000 to $9,000, often paid in cash, since it's not covered by insurance.
There are virtually no professional standards, any physician can claim and advertise that he or she is an expert in hair restoration. The training of many such "experts" is a three-day seminar. There is no way to compare surgeon success rates.
Anyone considering hiring a hair-transplant surgeon should ask for a list of a number of patients who have had the same surgery, then select a handful to see. Any surgeon who can't provide such a list should be dropped from your consideration. The four surgeons we list all said they provide such lists.

Hair transplantation Surgery Risks
As with any surgery, risk is a factor you must take into consideration before going ahead with hair transplantation. These include reactions to the local anesthetic and sedatives, infection of the donor and transplant sites, numbness around the donor or recipient site (usually temporary) and in the worst case, failure of the hair to survive the procedure. You must only ever consider using an experienced, reputable specialist dermatological surgeon.
Do your homework, shop around, make visits to their offices for consultations and ask to see plenty of before and after photos of their previous work. The results of your surgery will be permanent and this is a procedure for which you’ll have to part with the best part of tens of thousands of dollars. For the sake of a couple of extra months wait while you do your research, be patient and get it right.

Following your common sense is the key to a successful hair transplant.
