Is there a surgery for hair loss?

No.: No. But there is surgery for "baldness". This is to remove the bald part of the scalp and pull the hairy part together. This is called bald spot reduction.

Hair transplant: Hair transplant surgery is a procedure in which hair is moved from the back and/or sides of the scalp, where the hair is permanent (donor area), to areas that are thinning or bald on the front, top, or crown of the scalp (recipient area). Once transplanted, the hair will continue to grow for a person’s life time.
