Hair transplant surgery involves moving hair from one part of the body to another part--generally the head. However, the texture and composition of your hair can impact how successful a transplant is. For this reason, black men have a few more considerations than men of other ethnicities when it comes to deciding on a hair transplant.
Hair transplants simply move hair from an area of dense growth to one of less dense growth. When the transplant is successful, this results in hair growing in a new spot regardless of race or gender.
Since the process moves the the entire hair follicle, the shape of the follicle will determine the success of the transplant. Black men's hair follicles are often curved, which can cause the hair to grow back into the scalp and the transplant to fail.
If you have had a problem with "shaving bumps," which often lead to ingrown hairs, this indicates that your hair follicles curve and you are less likely to experience success with a hair transplant.
You can usually determine the type of follicle you have without shaving your hair. If your hair is wavy but not curly, then your follicles will probably be acceptable for a hair transplant.
It is best to work with surgeons who have experience with black hair transplants. They will be able to help you determine ahead of time your likelihood of success.
Consult your doctor if you experience sudden hair loss. It can indicate serious health problems.
