Does PCOS cause facial hair (hirsutism)?

Note on the name: in May 2026, polycystic ovary syndrome (PCOS) was formally renamed polyendocrine metabolic ovarian syndrome (PMOS), following a global consensus process. The old name was inaccurate — the condition affects multiple hormone and metabolic systems, not just the ovaries, and "polycystic" wrongly implies ovarian cysts. Nothing about the condition, its diagnosis or its treatment has changed. Both names will be used side by side for the next few years, and we use PCOS below since that is the term most people know.

Yes — hirsutism, meaning coarse dark hair in a male pattern, is a common feature of PCOS driven by raised androgens. It typically affects the upper lip, chin, jawline, chest, abdomen and inner thighs. Two approaches, and they do different things. Hair removal — laser, electrolysis, threading, waxing — deals with hair already present. Laser is the most effective for coarse dark hair on lighter skin, though it requires multiple sessions and maintenance. Medical treatment reduces androgen levels and slows new growth, but does nothing about existing hair. The two work best together, and expectations matter: because treatment only affects new growth, it takes six to twelve months before you can judge whether it is working. People frequently abandon medication at three months believing it has failed. Worth saying plainly: hirsutism is one of the most distressing aspects of PCOS for many women, and it is often minimised as cosmetic. It is not vanity to want it treated, and it is a legitimate reason to seek care in its own right. If hair growth appeared suddenly or is progressing rapidly, that needs prompt assessment.
