Natural-looking hair transplant results are possible today thanks to advancements in the procedure, with improvements including placing a few healthy hairs at a time and creating a more natural-looking hairline. Men and women are both good candidates for hair transplants, provided they have enough healthy hair on their scalp that can be transplanted and have the ability to grow hair on the thinning area of the scalp. Most transplants take between four and eight hours and only require anesthesia that numbs the scalp. Results can typically be seen between six and nine months after surgery, or sometimes 12 months.
