Sex – Men usually experience localized hair loss, known as male pattern baldness. It is much easier for the doctor to place grafts in correct locations on the scalp because the bald areas are obvious. Women, on the other hand, usually experience thinning throughout the head. It isn’t as easy to know which areas to target with the grafts. Occasionally, women also have localized thinning, which makes them much better candidates for hair transplants.
Age – Men who are just beginning to lose hair are not the best candidates, as the hair loss usually continues for several years. If grafts are placed too early, there is a possibility of incorrect distribution on the head. Men should seek transplants after they have experienced hair loss for more than 5 years and the balding has ceased.
Extent of hair loss – If there is an established area of hair loss, it is much easier for the doctor to place grafts in the correct area.
Scalp laxity – Hair can be removed from the donor area of the head more easily if the scalp is loose rather than tight.
Density – The number of hairs per unit of surface area determines a person’s hair density. A higher density means that there is more hair available to be transplanted. If hair on the donor area of the scalp is already thin, there is not much hair to cultivate.
Type – Hair that is thicker and coarser produces better results for hair transplants. Wavy hair is an asset, as it is more dense in appearance than straight hair.
