Diseases of the Hair

  • Herbert O. Mackey


A hair is a filiform conical structure, the enlarged bulbous extremity of which, known as the bulb, embraces the hair papilla. The bulb and a small portion of the shaft are contained in a pocket or invagination of the skin called the hair follicle. The hair shaft consists of the sheath or cuticle, the cortex beneath this; and a central medullary canal (which may be absent). The follicle is lined all the way with stratum mucosum; the upper third has the stratum corneum as well.
