Which type of hair is typically thick and dark, growing after the lanugo stage?

The type of hair that is typically thick and dark, growing after the lanugo stage, is terminal hair. Terminal hair is characterized by its coarser texture and darker pigmentation compared to other hair types. It is found in various areas of the body, including the scalp, eyebrows, and after puberty, in regions such as the underarms and pubic area.

During the lanugo stage, which occurs in fetuses, fine and soft hair covers the body, but as development progresses and exposure to hormones increases, terminal hair starts to replace lanugo. This transition signifies the maturation of hair follicles and the development of more robust and pigmented hair, which is a common process in humans as they grow and undergo various hormonal changes. The other hair types, such as vellus hair, are finer and lighter, making them distinct from terminal hair.
