Vp biden had that hair transplant years ago and still looks good. do you need to redo or add to it once its done?

Maybe: It probably depends on how the hair transplant is performed. The hair that is transplanted will continue to behave as it would have based on where it came from. There are certain parts of your scalp which are more likely to go bald. Hair taken from those portions less likely to go bald will continue to grow. It is also affected by your rate of hair loss, and the artistry of the surgeon.

Often yes: Male pattern baldness slowly progresses every year for most individuals. After several years new areas of thinning may need treatment. Propecia (finasteride) treatment can retard this loss fortunately.

Perhaps: Hair can only be added to bald areas. In a few years, as moe hair is lost, the original bald areas may be bigger, but the area of transplanted hair will be the same size. This can lead to a bald zone around the area of transplanted hair. If you don't like that look (who would!) the new bald strip between the hair not yet lost and the transplanted hair will have to be filled in with new grafts.

Pts vary: Some do, some don't.

On occasion: Occasionally male pattern baldness will advance to beyond the initial areas effecting the frontal hairline with regression behind the grafted area to involve the crown as well. Typically the grafts will be well maintained for the vast majority of your lifetime according to the donor site characteristics.
