Some vellus hair is replaced with terminal hair because of hormonal changes during puberty. Which type increases?

Explanation:
Puberty brings hormonal changes that drive vellus hair to become thicker, longer, and darker, transforming into terminal hair. This terminal hair grows in areas like the underarms, pubic region, and, in males, the face, due to the action of androgens. Lanugo hair is fetal and typically shed before birth, so it doesn’t increase during puberty. Vellus hair remains fine and light and doesn’t gain the heft or pigment of terminal hair. Club hair is a phase in the hair growth cycle, not a newly increased hair type produced by puberty.
