It was agonizing for this group of young people because thinning, balding, and receding hairlines often started before they got out of their teens. Now the procedure is being opened to young men - but with restrictions. Because losing hair at such a young age is very traumatic, hair transplant doctors do not like to go along with the patients' snap decisions. Almost everyone who has hair transplant surgery has swelling in the forehead and around the eyes. This lasts for only a few days, the worst being about the fourth day. Some people exhibit a black eye as a result. 6. Numbness. A hair transplant patient will feel numbness for several weeks after the surgery. When doctors do hair transplant surgery to replace eyebrows, they have to make sure that they put the hairs in so that they will point in the natural hair direction. For this, the surgeons use very fine gauge needles. They must also use this to help the hair to lie flat. Because the eyebrow hair is made of individual hairs, hair transplant surgery must involve creating those single units of hair. 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. He must also be very artistic to achieve a natural look, especially at the hairline. The direction the hair grows, both on the front of the head and at the crown, are very important, too. The doctor must make the condition of the newly placed hair look like the patient's own natural scalp hair. The angle that the hair is put in determines how much it will stand up from the head. Unfortunately, there are hair transplant surgeons who do not take their position of respect seriously. Some doctors are even transplanting donor hair into areas where the patient still has hair. Perhaps this is easier than placing it where it rightfully belongs - on the balding spots. For whatever reason, some hair transplant patients are not getting the number of grafts on their balding areas as they are billed.
