Cradle cap or Severe dry skin?

Rebecca • We have 2 angel babies and 3 babies this side of heaven and pregnant with our 4th!

My daughter is 6 weeks old and had this all over the top (only) of her head. Is it cradle cap or really bad dry skin? It isn’t really oily like cradle cap typically is. It looks like she has dandruff when you pick her up off her blanket or changing pad. She has extremely sensitive skin and we have had to switch everything to fragrance and dye free items. Any suggestions?
