Which gland is directly responsible for hair production?

The gonads are directly responsible for hair production due to their role in hormone regulation, particularly androgens, which include testosterone. These hormones play a critical role in the development of secondary sexual characteristics, influencing hair growth patterns in various areas of the body, including the face, chest, and pubic region.

The hormones produced by the gonads stimulate the hair follicles, leading to the growth of hair during puberty and other hormonal changes. This hormone-driven process distinguishes the role of the gonads from other glands, which may have different primary functions, such as regulating metabolism or growth rather than directly influencing hair growth.
