Is it bad to put body lotion on the scalp if it's dry? Preferably aveeno (oatmeal).

Dry scalp. There is not a contraindication to put a gentle lotion as aveeno (oatmeal) on the scalp. However, it may not be cosmetically elegant. There are scalp oils that are more appropriate and that will have more hydrating properties. Try macademian oil , rosemary oil or argan oil formulations. The rosemary oil brand that i like is by weleda.
