Top hair transplant surgeons are usually affiliated to various professional hair transplant institutes like the International Alliance of Hair Restoration Surgeons, etc.
Hair replacement or hair transplantation procedures utilize your existing hair and are generally successful provided you go to an experienced dermatologist who has the skills to perform the procedure.
