Formation of Hair Follicles
The formation of the epithelial bud on the outer surface of an embryo is the
first visible indication that a collection of stem cells is being instructed to
start the process of specializing. As the stem cells begin
The first identifiable hair follicles appear at about 9 weeks of age, after the embryo has begun to mature into a fetus. The first follicles develop in the areas that will eventually become the eyebrows, upper lip and chin. Hair follicle development on body, face and scalp then occurs in successive waves beginning at fetal age of 4 to 5 months. The fully mature 9-month fetus usually has all of the hair follicles that will ever develop in that person. It is believed that, under normal circumstances, new hair follicles do not develop in an adult. Molecular signals tell the specializing cells in the epithelial bud to elongate into the cellular structure that eventually becomes the fully developed hair follicle. At a later stage of development, the cells responsible for hair pigmentation (melanocytes) are instructed to intersperse among the other cells of the developing follicle. The developing follicle also incorporates a sebaceous (oil) gland that will subsequently supply lubrication for the hair that will grow from the follicle. The developing follicle is instructed by molecular signals to develop at an angle relative to the skin surface; thus, the hair growing out of the follicle will grow out at an angle relative to the skin, not straight up like the bristles of a brush. However, tiny muscles that develop in skin next to the follicle can pull the hair straight up. This happens in response to cold external temperature when hair is pulled straight up to form a thermal layer and give the skin better protection against cold air. When this happens we also feel a prickling sensation that we call “having goose bumps”.
