Any doctors who make decisions that are not based on the welfare of his patient are following their Hippocratic Oath in its intentions. Doctors are held to a high standard and when a surgeon tries to convince a patient to get hair transplant surgery when it is not best for him, he is not really acting as a doctor should. The injections of the local anesthetic into the scalp before hair transplant procedures are definitely painful to some degree. Anyone who has had a tooth pulled knows that, if the tooth is deadened properly, it is not the tooth-pulling that hurts. It is the needle going in with medication to numb the tooth that is the real agony. People realize that men have receding hair lines and balding on the tops of their heads. It is not out of the ordinary to see a woman with thinning hair. Yet, look at a person without eyebrows and the effect will be disturbing. Eyebrows are just expected. Some people have hair transplant surgery to their eyebrows because the hair has simply fallen out over time. The follicular units are small and they can be separated from tissue that has no hair, under the microscope. That way, only the tissue that grows hair is transplanted. It is a much more efficient procedure in that way. Follicular units placed during hair transplant procedures are put into tiny holes the size of needles. The truth is that you have many small wounds and you need to protect them. 4. Hair transplant can be a time-consuming commitment. Treatment can often last one to two years. Mega-sessions where thousands of grafts are done in one sitting help to shorten the overall time. However, the length of these sessions is often grueling. For whatever reason, some hair transplant patients are not getting the number of grafts on their balding areas as they are billed. This is testified by certain doctors who have seen the results. The density of hair on these patients' heads is not commensurate with the number of grafts they supposedly got.
