Our hair goes through natural cycle of hair growth & fall. Hair fall/alopecia can not be quantified, as in some cases losing 30-40 hair per day would be abnormal or in some even losing 100 hair would be normal. Most common causes of hair loss are dietary deficiency (proteins, iron, zinc, vit D, B, C, calcium) hormonal changes (thyroid, pregnancy, PCOS) some medicines, scalp disorder (dandruff, psoriasis, folliculitis) stress, heredity (Androgenic Alopecia). Depending on cause & with tretment we can control hair fall.
