What is a hair graft and follicle?
Hair is made up of 2 parts: the hair follicle and the hair shaft. The hair follicle anchors the hair into the scalp and is made up of the papilla and bulb, which are located beneath the scalp. The bulb can be found at the bottom of each strand containing the active cells which grow the hair around the papilla. The papilla provides the blood supply to the hair follicle to encourage healthy hair growth.
The hair shaft is the visible hair that grows out from the follicle which is made up of a hard protein called Keratin and a protective layer called the cuticle. They’re over 100,000 hair follicles on a full head of hair. Hair grows in cycles and it is common for people to lose up to dozens of hairs each day.
