Terminaalikarvat

Terminaalikarvat, known scientifically as terminal hairs, are the thick, coarse, and often longer hairs that grow on the human body, especially after puberty. They are distinct from vellus hairs, which are the fine, short, and light-colored hairs that cover most of the body's surface in childhood. The growth of terminal hairs is largely influenced by hormones, particularly androgens.

These hairs typically appear in specific areas that are referred to as secondary sexual characteristics. In males, these include facial hair (beard, mustache), chest hair, and abdominal hair. Both males and females develop terminal hairs in the axillary (armpit) regions and pubic areas. Post-puberty, androgens also stimulate the growth of terminal hairs on the scalp, which can lead to patterns of hair loss in some individuals. The texture, color, and density of terminal hairs vary significantly among individuals due to genetic factors. Changes in terminal hair growth, such as excessive growth (hirsutism) or loss, can sometimes indicate underlying medical conditions or hormonal imbalances.
