Hair follicle

Definition and stakes

Francis M. Walters Physiology and Hygiene for Secondary Schools

A Hair is a slender cylinder, formed by the union of epidermal cells, which grows from a kind of pit in the dermis, called the hair follicle. The oval and somewhat enlarged part of the hair within the follicle is called the root, or bulb, and the uniform cylinder beyond the follicle is called the shaft. Connected with the sides of the follicles are the oil, or sebaceous, glands (Figs. 121 and 122) . These secrete an oily liquid which keeps the hair and cuticle soft and pliable.

The roots of the hair are formed in the hair-follicles, which may be described as little pear-shaped bags, formed either in the true skin or in the cellular tissue beneath it. Each hair-follicle, hair-sac, or hair-pit, as it is variously termed, bulges out at its deeper part, contracting to a long narrow neck as it passes to its skin. Near the surface of the latter the follicle widens out again, and it is from this part that the hair emerges. As it has been previously mentioned, a duct from one of the oil glands usually opens into each follicle.

George Henry Fox Skin Diseases of Children (1897)

The slight growth of hair which persisted after the affected skin had become smooth and comparatively normal in color was destroyed by the introduction of the electrolytic needle into each separate follicle, according to the method employed in the treatment of superfluous hair. The young man now presents not the slightest deformity of the eyelid, and scarcely a trace, upon close inspection, of the dark, warty, and hairy growth which formerly attracted attention wherever he went and was the source of great mortification.
