Greetings! Thanks for your query. As you are rightly suspecting the problem of acne and hair fall is most likely to be due to hormonal imbalance. Your condition needs thorough evaluation and assessment by a Dermatologist and a Gynaecologist (who need to work together) to achieve the best outcome in your case. For dandruff problem you can use shampoo containing Ketoconazole twice a week for 1 month followed by once weekly till problem is resolved.
