During the final, or exogen, phase, “old” hair sheds, though usually, a new hair is getting ready to take its place. Wherever you have hair on your body, you also have hair follicles. Hair follicles originate in the first and second layers of your skin (epidermis and dermis).

These layers are bound together by the cell membrane complex (Robbins, 2012). Next is the telogen or resting phase of the hair cycle, in which the hair follicle is dormant, and growth of the hair shaft does not occur. The exact mechanism that controls passage from one phase into the next is not fully known. The outer root sheath (ORS) has been recognized as a ready supply of multipotent stem cells that differentiate into several cell types, including melanocytes and keratinocytes. More specifically, these stem cells are thought to reside in a distinct bulge area located between the insertion of the arrector pili muscle and the ductal opening of the sebaceous gland. In the deepest portion of the each hair follicle lies the hair bulb.

Hair is extremely sensitive to air movement or other disturbances in the environment, much more so than the skin surface. This feature is also useful for the detection of the presence of insects or other potentially damaging substances on the skin surface. This is visible in humans as goose bumps and even more obvious in animals, such as when a frightened cat raises its fur.

Every Saturday morning, my mom would sit us down to oil our scalps with a special blend of coconut oil, amla oil, almond oil, and castor oil. Now that I live on my own, I still take the time to oil my scalp once a week—but rather than make my own blend, I use one of the many hair oils on the market. And dare I say, it's the reason I constantly get compliments on my healthy, smooth, long hair. Keep reading for my product recommendations, as well as how to properly oil your hair and how often you should be hair oiling, according to experts.

These layers are depicted in a longitudinal cross-section of the hair follicle (Figure 2), although not all hair has a medullary layer. Hair is made of a protein called keratin that is produced in hair follicles in the outer layer of skin. As follicles produce new hair cells, old cells are being pushed out through the surface of the skin at the rate of about 6 inches a year. The hair you can see is actually a string of dead keratin cells.
Besides this, not much is known about the effects of protein, keratin, and vitamins on hair health. Topical ointments are generally recommended for people who experience hair loss and may help your hair grow. The set includes almond, avocado, castor, coconut, and grapeseed oils. If you’re new to carrier oils, this is a good way to try multiple types without investing in larger bottles of each.
One idea is that body hair helps keep us warm in cold weather. When the body is too cold, arrector pili muscles contract and cause hairs to stand up (shown in Figure 10.5.5), trapping a layer of warm air above the epidermis. However, this is more effective in mammals that have thick hair or fur than it is in relatively hairless human beings.
