These symptoms, oily skin, hair loss, and facial darkening, often point to an underlying hormonal imbalance, such as PCOS or insulin resistance. Precautions: Wear SPF 50+ sunscreen daily to prevent further darkening, limit high-glycemic foods, and avoid harsh physical scrubs. Recommended Products: Skin: Use a Salicylic Acid cleanser (to control oil) and a Niacinamide or Vitamin C serum (to fade pigmentation) under a broad-spectrum sunscreen. Hair: Use a mild, sulfate-free shampoo. Topical Minoxidil (2%) can help with hair fall, but consult a doctor first. Next Steps: Please consult a dermatologist or gynecologist for hormone and thyroid blood tests to treat the root cause.
