Definition of Terminal Hair:
Terminal hair, commonly called body hair, is typically characterized by its dense and dark appearance. The condition can affect multiple body regions, such as the scalp, face, armpits, and genital area. Terminal hair functions as a protective barrier for the body in various aspects. Maintaining a stable core temperature can be achieved naturally. It protects against the sun’s harmful rays to ensure the safety of your skin.

Both children and adults possess terminal and non-terminal hair. The development and speed of terminal hair growth are influenced by several hormonal variables regulated by the endocrine system. Terminal hair growth is a secondary sexual characteristic that manifests during adolescence, similar to the development of breasts and penis. These changes in bodily functions are induced by androgens, a group of sexual hormones that are synthesized during the phase of puberty. The hormones exhibit differential sensitivity across different body regions ( Miranda et al., 2018).
