hii my Daughter is 18 months old. from last 1-1½ week she's having lots of hairfall. is this normal? and if not then what to do

A. Having 15 to 20 strand of hair coming out every day is not hair fall but if it is more than that then you should start with an iron supplement for your child or sometimes it could be due to deficiency of iron in the body and sometimes if the products like oil and shampoo are not suiting the scalp of your child
