I have facial hair, especially above my upper lip, that requires shaving occasionally. What causes this?

This is a condition called "hirsutism" (defined as excessive growth of facial and body hair). It indicates that there is a hormonal imbalance between estrogen, testosterone (the dominant male hormone) and progesterone. Progesterone acts as a regulator for the entire endocrine system. A woman who has the hirsute problem probably has PMS too. Both menopausal and menstuating women have reported that facial hair (and body hair) decreased or completely disappeard after three to six months of regular application of cream twice a day. Natural progesterone is needed to effect proper hormonal balance.
