A few chin hairs? Totally normal. A sudden thick patch? That might be worth a closer look. While many women deal with occasional facial hair, excessive growth can sometimes signal hormonal imbalances.
Hair follicles respond to testosterone, which all women produce in small amounts. When levels rise—due to genetics, age, or health conditions—fine vellus hair can transform into coarse terminal hair. This is why some women notice more chin hair as they get older.
But if the hair is dark, thick, and spreading quickly, it could be hirsutism. Conditions like PCOS are a common culprit, affecting hormone levels and leading to symptoms like irregular periods and weight gain. Rarely, adrenal tumors or disorders like Cushing’s disease can also trigger excess hair.
If you’re concerned, track your symptoms. Sudden hair growth paired with acne, fatigue, or voice changes warrants a doctor’s visit. Treatment depends on the cause but may include hormone therapy or lifestyle changes.
