Who Are the Best Hair Replacement Surgeons in the USA?

There are always many good physicians in any field. However, there are few great physicians in any area. The best way to discover these doctors is to read online reviews in unbiased forums related to hair restoration surgery. Then you must evaluate their results.  If the physician has only a few results, you can forget this physician. Results should allow the viewer to inspect the results closely. Don’t focus solely on results where patients had very little hair loss. Look at the results that showed a higher degree of hair loss.  If the physician’s results do not let you zoom in for a closer inspection, be wary of those results.  The physician may be hiding something like concealers to make the result appear better than the result is.  Look at lighting too, when you inspect results.  If the before photos are overexposed and the after picture is underexposed, with too little light, be cautious of this result.  If the results on the physician’s website are not excellent, you can forget the reviews.  Many physicians are very good at getting patients to post reviews a few days after procedure.  These reviews are useless.  You want reviews after the grafts have grown in.  In summary, look for great reviews after the grafts have grown in.  Then inspect the physician’s website. Look for great results. If you find both, you can dig a little deeper into this physician. If you don’t see both, go on to the next physician.
The very best hair transplant physicians are also the physicians who perform repair work. Repair work is much more difficult than working on a virgin case.  If the physician has great repair work, you can bet that he has great results on patients, who have never had a hair transplant.  Only the very best physicians get great results on repair cases.  Then consider experience. It requires 10,000 hours to become an expert in any procedure. In general, this equates to 5 to 10 years of experience doing the same thing every day. For most hair restoration surgeons, this means more than ten years because they perform few procedures or because they perform many different kinds of procedures.  A physician that offers multiple types of restoration procedures is not going to be as good at either one.  A physician, who focuses on a single procedure will be much better at this procedure.  

You are asking a bunch of surgeon who is the best surgeon.  Do you really expect to get the answer you're looking for?

I advise you to study and research which hair transplant method you want to use (FUT, FUE, BHT?) and go to a clinic/surgeon who specializes in that method. Different techniques use varying tools/technology, require specific experience, and demand a unique skill set. For the best results, you want to go to a master of one, not a jack-of-all-trades. Best of luck.
