Hair Vellus: Usage Explanation

Hair Vellus is a type of soft, fine, non-pigmented hair found primarily on the human body. It is usually located on the upper back and chest area in the form of small, vellus hairs. It is a different type of hair compared to the hair found on the scalp or face. It is finer and lighter, usually not as long as the hair found on the scalp or face.

The main purpose of vellus hair is to act as insulation for the body against temperature changes. It acts as a protective layer to prevent heat from radiating off the body and allows the body to maintain a consistent temperature in cold weather.

The usage of vellus hair also includes regulating body temperature in hot weather. The hair helps to release heat from the body and allow for increased levels of sweat production and cooling of the skin.

Vellus hair is also important for providing nutrients and oil to the skin. It is believed that the sebum present in vellus hair aids in lubrication of the skin, prevent water loss and provide a protective barrier against bacteria.

Overall, vellus hair serves many important functions for the body and is an essential part of keeping the skin and body healthy.
