Excessive hair growth on the stomach is commonly associated with hormonal fluctuations in women. "It can be a common concern for women during pregnancy and menopause, and it can also be linked to PCOS (polycystic ovary syndrome),” explains Dr. Shotter. "Some medications, such as steroids and minoxidil, can also cause unwanted hair growth." If you have several coarse hairs appearing, it could be a sign of a medical condition called hirsutism. Hepburn suggests discussing it with your doctor if it is a concern.
