Yes. The hair around the back and sides of your head is selected as donor hair as, unlike the hair on the top of your scalp, it will grow back after extraction. Despite this, your donor hair can still be at risk of over-harvesting if your surgeon tries to remove too many follicles during one procedure, meaning the hair will not grow back fully. This is one of the reasons why it’s so important to thoroughly research a clinic and its surgeons ahead of time.
