Hello doctor. My daughter is 4 months 14 days old. She is feeding with nanpro . She was affected by Sebhorreaic dermatasis. I am using anti dandruff shampoo twice a week as per doctors advice for past one month. But my baby is feeling itchy on hair for Past three days and she is uncomfortable with that. Please clarify me how it will go. I heard that it will come due to using of formula milk. Please tell me is it true.
