Which condition is commonly associated with hair growth irregularities in women?

• A. Hypothyroidism
• B. Polycystic ovarian syndrome
• C. Alopecia areata
• D. Telogen effluvium

Answer: (B)

Hair growth irregularities in women are most closely linked to excess androgens, which drive hair growth in unwanted areas. Polycystic ovarian syndrome is a common source of androgen excess in reproductive-age women. In PCOS, the ovaries produce more androgens, and insulin resistance lowers SHBG, increasing free testosterone. This leads to hirsutism—excess facial, chest, and abdominal hair—and often accompanies irregular or absent menstruation. Other conditions change hair in different ways: hypothyroidism tends to cause diffuse thinning and brittle hair rather than new unwanted hair growth; alopecia areata causes patchy, autoimmune-driven hair loss; telogen effluvium produces diffuse shedding after stress or illness. Because androgen-driven hair growth best explains the irregular patterns described, PCOS is the most fitting association.
