Baby oil benefits: ear. Mineral or baby oil is good from treating common ear problems, such as wax build-up.

How Baby Oil Works. The hair is made of keratin, a form of protein and for most people the hair only grows one-half inch a month. But since the hair strand is dead, you can only make it look better.
