Follicular unit extraction is a type of hair transplant done by taking individual hair follicles from your skin and moving them to another part of your body where the hair's thinner or absent. It is frequently done on persons who have a hair loss problem. This procedure is commonly undertaken by younger patients and those who like to wear their hair shorter and where a scar would be more visible. It requires various factors such as age, the amount of expected hair loss, and the patient's general health to be taken into consideration.
