Girls, my dear ones, good evening to all. Our daughter is 11 months old. She recently had a cold, we didn't bathe her for a week and during this time she developed dandruff on her head, right tiny on the hair. I think it's because I didn't bathe her for a week or maybe it could be another reason. Could you please tell me if your children have dandruff? ☹️?Thank you in advance ?
