[/INST] Hello,Welcome to healthcare magic.I understand that you are having hair fall for more than a year.The causes of hair fall in your age group could be poor diet, stress, physical illness like fevers and hereditary type of baldness.You could continue taking a vitamin supplement containing 5 mg of biotin everyday. It will help to strengthen your roots.You could consult a dermatologist to assess the type of hair fall. Hereditary type of hair fall can be treated with minoxidil solution and finasteride tablets, both of which are US- FDA approved for hair fall. These have to be prescribed by your doctor.Have a good diet rich in vitamins and anti oxidants like fruits and vegetables.Hope this helps you.Take care. </s>
