This distinction leads to some body hair follicles producing pigmented terminal hair in response to androgen stimulation in adulthood when neighboring follicles continue to produce vellus hair. The hair follicles on the chin are highly androgen responsive in both men and women. Women with abnormally high androgen levels can grow beards. Note that whiskers are not the same as the vibrissae on rodents and cats. Vibrissae are specially modified follicles with numerous sensory nerve endings in an around the hair follicle structure to detect movement in the hair fiber.
Pubic hair is a kind of terminal hair type.
It is usually pigmented and of large diameter. The kinks in it make its appearance distinctive. They are terminal hairs and, as the name suggests, they surround the anus. Peri-anal hairs are distinguished from other hair types in the vicinity by their size and their unusually large associated sebaceous glands. Peri-anal hairs apparently produce a lot of oil if the size of the sebaceous glands are anything to go by.
