Hi There are several causes of hair fall and the commonest cause of hair fall in males is male pattern baldness(due to genetic and harmonal cause) which generally has no cure other than hair transplant Some drugs like topical application of Minoxidil can be of some use to reduce the hair fall but very unlikely that the lost hair will re grow In females Androgenic alopecia is the most common cause of hair loss in adult women.The diagnosis is made by ruling out other possible diagnoses through lab work, recognition of the distinctive pattern of hair loss You correct your anemia and try to change the shampoo which you are using for some time Consume foods rich in Vitamin E - like Avacodas, Vitamin K - dark green leafy vegetables Wish You Good Health Regards Dr Sridhar K
