What should you know about excessive hair growth hirsutism?

Hypertrichosis is excess hair growth in a body area where hair may normally occur. It can be present from birth or develop later, and it may affect a small area or much of the body. Hirsutism is a different pattern: coarse, dark hair develops in areas more commonly influenced by androgens, such as the face, chest, abdomen, or back in women. A clinician may consider family traits, medicines, hormonal conditions, and the timing of the change when working out the pattern.

The hair itself is usually not dangerous, but a new pattern can sometimes accompany a medical issue. Shaving, trimming, waxing, or depilatory products change the visible hair without addressing why it appeared.

Arrange a dermatology or primary-care assessment if the growth is new, bothersome, or spreading. Note when it began, where it is growing, whether the hair became darker or coarser, and any medicines or supplements started around the same time. Your clinician may examine the hair pattern and skin and ask about menstrual changes, acne, voice changes, scalp hair thinning, or other signs of hormonal change. Testing is chosen according to your history rather than automatically required for every person.

For cosmetic reduction, options can include temporary removal or longer-term reduction with a professional treatment. Discuss skin tone, hair colour, the treatment area, and the possibility of irritation or pigment changes before choosing an approach. See the pages on Laser Hair Removal and Electrolysis Hair Removal for more detail.

Book a prompt medical review if coarse hair appears quickly or is accompanied by a deeper voice, marked acne, increased muscle bulk, scalp hair loss, or changes in menstrual bleeding. Seek urgent care for sudden severe symptoms, facial swelling, trouble breathing, or a serious reaction after using a hair-removal product. These warning signs do not identify a diagnosis on their own, but they make timely assessment more appropriate.

Ask: Does this pattern fit hypertrichosis, hirsutism, or another cause? Could any medicine or supplement be contributing? Do my other symptoms suggest hormone testing? Which removal method suits my hair colour, skin tone, and treatment area? What skin reaction should make me stop a product and contact you?
