Terminal hair on the face alone in women may suggest an excess of what?

1. Estrogen

2. Testosterone

3. Progesterone

4. Insulin

The correct answer is: Testosterone

The presence of terminal hair on the face in women is often an indicator of hirsutism, which is frequently linked to an excess of androgens, particularly testosterone. Testosterone is a male hormone that is also present in lower levels in females. Elevated levels of testosterone can lead to male-pattern hair growth, which includes the development of thick, coarse hair on areas typically associated with male hair growth patterns, such as the face. Changes in hormone levels can significantly impact hair growth and distribution. While other hormones like estrogen, progesterone, and insulin also play roles in various bodily functions, they are not primarily associated with the development of terminal facial hair under normal or excess conditions in women. Instead, an imbalance in androgens, specifically testosterone, is the key factor that leads to this condition. This understanding is essential for evaluating hormonal health and guiding potential treatments for those experiencing hirsutism.
