Hair on a woman’s chin is commonly a sign of excess androgen (male hormone) activity. This can be associated with several conditions, most commonly:
- Polycystic Ovary Syndrome (PCOS) – the most frequent cause; often includes irregular periods, acne, and weight gain
- Hirsutism – a general term for male-pattern hair growth in women
- Hormonal imbalances involving the ovaries or adrenal glands
- Rarely, androgen-secreting tumors or certain medications
Not all chin hair is abnormal—some mild growth can occur due to genetics, aging (especially after menopause), or ethnicity.
If the hair growth is sudden, worsening, or accompanied by other symptoms (deep voice, irregular periods, severe acne), it’s worth getting evaluated by a doctor.
