If I speak honestly, you will definitely be pleasantly surprised. If you just read about the procedure then you may get the idea of pain but in actual, there is no pain with this surgical procedure. The latest technique, FUE hair transplant is completely painless and scar-free.
There may be little discomfort that can be cured with some medications. You can think like getting filling from dentists. The procedure is done under anaesthesia therefore there are negligible chances of pain.
