👉 Ascocotyle is a type of hair follicle that grows in the basal part of the scalp, often on the back or side of the head. It is characterized by its unique shape and size, with a narrow opening at the base for blood flow and a large, circular cell called an acropetal cell (also known as a "hairball") that secretes oils and lubricants to protect the hair follicle from damage caused by heat or other environmental factors.
