The study also reports that oats are high in antioxidants, as well as vitamin E and ferulic acid. These components of oat milk help skin and hair feel soothed and moisturized. Paired with essential fatty acids such as palmitic, stearic, oleic, linoleic and linolenic acid, oat milk has the potential to make damaged hair look smooth and healthy, according to the Journal of Agroalimentary Processes and Technologies.
