Hello, Welcome to health care magic. Severe hair loss over few months is called telogen effluvium. It is a hair loss pattern usually triggered by a physical illness ( viral fever, typhoid fever, hepatitis, etc), anaemia, childbirth, crash dieting, weight loss and thyroid abnormalities which you would have about 3 - 6 months prior to onset of hair fall. You need to check your hemoglobin levels, serum ferritin levels and thyroid status. You would benefit from taking vitamin supplements containing biotin, calcium pantothenate and minerals for a duration of atleast 3 months. Biotin rich foods are carrots, almonds, walnut, cucumber, cauliflower, milk and eggs. Eggs also have protein and amino acids required for hair growth. Hope this helps you. Take care.
