A hair transplant doesn't grow new hair.

A hair transplant doesn’t grow new hair. It moves existing follicles from a stable donor area (usually back and sides of scalp) to thinning recipient areas.

Done well, the transplanted follicles continue to grow normally for the rest of your life. Done badly, you get an unnatural hairline, low yield, donor-area scarring, and a scalp that looks worse than before.

Realistic expectations: transplanted density is 30–50 follicular units per cm². Original full hair is 60–100. The result looks full because the area is reconstructed, not because density is matched. Most patients also need to continue medical therapy (finasteride, minoxidil) afterwards to slow further loss of native hair around the grafts.
