Hii You could be having androgenetic alopecia, a type of hair loss that occurs due to high testosterone levels and tends to run in family. Dandruff is also another cause of hair loss. Plz use a ketoconazole containing shampoo twice a week. You can use minoxidil lotion fir your hair loss. But before examination it's very difficult to say. You can see a dermatologist for the same.
