Human Hair: A Short History and a List of Functions

A woman dramatically whipping her hair outHumans, like all other animals that ever walked on Earth, are the product of evolution. How the human body looks and functions are based on how man’s evolutionary journey determined it.

One good example of this determination is human hair. Humans still have the same number of hair follicles as apes, but humans have hair on the body that is a lot finer in texture. Longer and thicker strands of hair have become concentrated on particular spots, such as the head, as man began walking upright and using items to cover their body.

Functions of Hair

  • The hair on your head has several functions, and its location alone is indicative of these functions. Hair lends some protection to the scalp, as it’s the part of the human body that’s most exposed to the sun. In cold weather, on the other hand, the hair traps body heat to help keep you warm. Your hair also plays a role in keeping sweat out of your face, and keeping your scalp moisturized by trapping natural oils.
  • The most obvious role that hair plays has to do with looks. The hair on your head frames your face. As people have different face shapes, features, skin color, and facial musculature and size, some hairstyles look better on some than on others.
  • Such is the importance of head hair that many are willing to undergo hair loss treatment in Utah clinics and other facilities. Utah Scalp Aesthetics added that while people have some sort of control of their body, you couldn’t go against genetics and signs of aging.

Some people, particularly men, are more accepting of hair loss as they get a little older. For many, particularly among women, losing their hair is a nightmare that makes a trip to a treatment clinic extremely necessary. If you are concerned about losing your locks or a receding hairline, you might want to make that trip too and find out more about the condition and possible treatment.
