It is possible that head hair was retained because it protected the scalp from UV light. As our bipedal ancestors walked on the open savannas of equatorial Africa, the skin on the head would have been an area exposed to the most direct rays of sunlight in an upright hominid. Pubic and armpit hair may have been retained because they served as signs of sexual maturity, which would have been important for successful mating and reproduction.

Vitamin C also helps your body absorb iron, which is necessary for hair growth. Vitamin E also protects areas of the skin, like the scalp, from oxidative stress and damage.

In one older study, people with hair loss experienced 34.5% more hair growth after taking a vitamin E supplement for 8 months (17).

A healthy lifestyle of low stress, proper diet, and gentle hair care should help promote healthy hair growth for a long time. The first three phases — anagen, catagen, and telogen — cover the growth and maturation of hair and the activity of the hair follicles that produce individual hairs. During the final, or exogen, phase, “old” hair sheds, though usually, a new hair is getting ready to take its place.

It consists mainly of tightly packed, keratin-filled cells called keratinocytes. The human body is covered with hair follicles, with the exception of a few areas, including the mucous membranes, lips, palms of the hands, and soles of the feet. Signals due to the coiled-coil organization of α-helical keratin proteins and intermediate filaments in the cortex, and lipids in the cell membrane complex were observed in the hair of all individuals. The typical mammalian hair consists of the shaft, protruding above the skin, and the root, which is sunk in a pit (follicle) beneath the skin surface. Except for a few growing cells at the base of the root, the hair is dead tissue, composed of keratin and related proteins. The hair follicle is a tubelike pocket of the epidermis that encloses a small section of the dermis at its base.
