The hair follicle contains oil-secreting glands, which make the hair shiny. Stress and illness and lack of proper nutrients diminish secretion of oil and pigments causing graying of hair. The hair is considered as a tissue which uses the same nutrients of bone, nails and which is formed as bi-product of bone tissue.
Hair follicles forms a cluster of cells in the upper layer of the skin. These cluster of cells are called the primitive hair germ, which needs nourishment to grow into a dev â¦ eloped hair follicle. To get nourishment it works all the way down into the lower layer of the skin. That black bump (which is clear or white in blonde hair) is not the follicle itself but the root of the strand. Think of it as the bulb of a flower. Your hair follicle i â¦ s part of your scalp.
