Also called: polycystic ovary syndrome hair loss · PCOS alopecia
Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of reproductive age, characterised by hyperandrogenism, ovulatory dysfunction, and polycystic ovaries. Elevated androgens drive both scalp hair miniaturisation (FPHL) and unwanted facial/body hair (hirsutism).
In PCOS, insulin resistance promotes excess ovarian androgen production (predominantly testosterone and DHEA-S). Elevated androgens, particularly DHT converted at the follicle by 5α-reductase, trigger the same miniaturisation pathway as androgenetic alopecia. The co-occurrence of acne, oligomenorrhoea, and hirsutism alongside scalp hair loss is the clinical hallmark.
PCOS affects 9–22% of Indian women of reproductive age - higher than global averages, likely due to metabolic predispositions in South Asian populations.
Tests are performed by a qualified dermatologist or trichologist after clinical assessment.
Anti-androgenic OCP (e.g., drospirenone-containing) reduces free androgens and improves scalp hair and acne.
Androgen receptor blocker. Effective for scalp hair loss and hirsutism. Requires monitoring.
Improves insulin sensitivity, reducing ovarian androgen production. Most effective in insulin-resistant PCOS.
Reduces insulin resistance - the root driver of androgen excess. Most cost-effective intervention.
Addresses the scalp hair loss component directly, independent of systemic androgen management.
Timeline: Hormonal treatment takes 3–6 months to produce visible improvement in hair density. Combined topical + systemic approach produces the best results.
All women with suspected PCOS should have a formal gynaecological + endocrine evaluation. Hair loss is rarely the only manifestation - a holistic hormonal workup is essential.
“PCOS-driven hair loss is one of the most rewarding to treat because the hormonal component is modifiable. I often see dramatic recovery when the right combination of anti-androgen therapy and insulin sensitisation is established - the scalp responds once the systemic environment is corrected.”
