It is the needle going in with medication to numb the tooth that is the real agony.

Swelling is normal after hair transplant surgery and can even keep you away from work. Micro grafts are useful in hair transplant surgery because they can give the hair a quite natural appearance. The hair emerges from the scalp in the most natural way, with the same number of hairs that nature intended. If the procedure is done correctly, no one can tell the difference. Natural looking hairlines have been difficult to achieve with hair transplant surgery. If your doctor says to try a few hair transplant grafts and then decide, run. This is never a good idea. Once you start having the grafts done, you are committing to a full set of procedures. Otherwise, your hair will end up looking out of balance. 5.
