A hair transplant is a procedure to move hair to an area that's thin or bald. Hair restoration surgery involves removing a small strip of hair-bearing scalp from the back and sides of your head. This donor region contains hair that will grow throughout your lifetime. The area from which the strip is taken is carefully closed, usually resulting in a very fine line completely hidden amongst the remaining hair.
There are two types of transplant procedures: slit grafts and micrografts.
Slit grafts contain 4 to 10 hairs per graft. Micrografts contain 1 to 2 hairs per graft, depending on the amount of coverage needed.
