Hi, I can understand your concern for hair loss. Hair fall can be due to any long term illness or any emotional or stressful event and due to nutritional deficiency or hormonal influence. I can make out that you are female but you have not mentioned your age so that a better hormonal therapy could be suggested. It would be best to start with proper hormone related medicines to control PCOS as well as hair fall. If I were your dermatologist then would have prescribed you tablet containing Acetylcysteine, Calcium Pantothenate, Selenium, Zinc, Biotin, Copper as active ingredients. You can take these vitamins in the form of biotin, calicium pantothenate and other vitamin B complexes. You can start minoxidil lotion under strict dermatological guidance. Take care.
