When the hair falls from our head, becomes thinner, notice that the hair in the back of the head (occipital) is still thick. Baldness does not come from behind. The follicles there get stronger with age- the frontal plaques are lost but don’t backward. In the hair transplant, some of the strong follicles in the back are to pick up for the small holes in the front emptying area. Then they are reared with drugs. It is also an expensive treatment. A hair transplant shouldn’t be done for children. Once transplanted, it takes 6-8 months for men and about two years for women to see good results. Then the drugs have to be taken for a long time. The number of hairs on the scalp is the same, Just need to be well distributed.
