Can you tell me how could i stop my hair falling out?

See your doctor: Depending if you're male or female, there are numerous causes of hair loss. Minoxidil is an over the counter remedy that is believed to work by increasing blood flow to hair follicles. Biotin deficiency is easily corrected by taking at least 3000 micrograms of biotin per day. It also helps to control any dandruff or itching in the scalp. Dramatic hair loss may be a sign of a medical problem.
