How often should I wash my baby’s hair with cradle cap? (8.5 months now)

Charlene

Hi! My baby had cradle cap when she was maybe 2 months old and got pretty bad at 3 months old. We did the mineral oil and brush treatment once and a lot got off. I was on the fence about using mineral oil again and I thought the little remaining would eventually fall out after enough washing. We wash her hair once a week to 10 days since her hair doesn’t seem dirty or greasy, even though we give her a quick water bath almost every day as a part of the bed time routine. But after 5 months the little remaining cradle cap is still there. Would it not go away by itself and I have to do the mineral oil treatment until it’s totally clear? Or is it that I am not washing her hair often enough? Thank you!
