When your scalp is healthy, an oily material called “sebum” moisturizes your scalp and keeps your hair looking soft, smooth and glossy. One of the best ways to keep sebum production up is by ensuring you get lots of vitamin A, reports researchers. Getting too little of this nutrient can cause sebum to dry out, which impacts your scalp health and hair health.
Interestingly enough, not only does vitamin A keep hair looking like something in a hair commercial. A lack of vitamin A has also been linked to hair loss in studies.
