Causes of unwanted hair growth in females

Polycystic ovary syndrome is a frequent hormonal cause and may present with hirsutism, irregular periods, acne, or difficulty ovulating. Some people have no identifiable disorder, while medicines and less common ovarian, adrenal, thyroid, or pituitary problems can also contribute.

Hirsutism refers to thick, dark hair in androgen-sensitive areas such as the upper lip, chin, chest, abdomen, back, or thighs. Fine, pale hair and gradual changes around menopause may reflect normal variation rather than the same hormonal process.

Timing provides useful clues. Gradual growth with irregular cycles fits a different pattern from hair that appears quickly alongside scalp hair loss, a deeper voice, or increased muscle bulk. Steroids, some seizure medicines, and hormone products should be included in the medication review.

Book a routine appointment if the hair is new, distressing, or accompanied by acne, cycle changes, weight changes, or problems conceiving. Note when it began, which areas are affected, menstrual dates, and all prescription medicines, supplements, and hormone products.

A clinician may examine the hair distribution, skin, and scalp and may order hormone or thyroid blood tests. Treatment is tailored to the cause and your priorities. Hair-removal methods act on existing hair; prescription options aim to slow new growth. The combined pill can help some people but requires a safety review and is not suitable for everyone.

Request prompt medical assessment if thick dark hair develops rapidly, particularly with a lowering voice, new muscle enlargement, or marked scalp hair loss. A fast change can signal a substantial hormone shift that needs investigation.

Also arrange care if periods become very irregular or stop unexpectedly, or if symptoms begin after starting a medicine or supplement. Do not stop a prescribed drug suddenly; bring its name and dose to the appointment so the prescriber can advise safely.

Useful questions include which hormonal causes fit your pattern, whether blood tests are needed, and how long treatment may take to affect new hair. Mention pregnancy plans because they influence which hormone treatments and topical medicines are appropriate.
