Vitamin E is a powerful antioxidant often used in hair and scalp products because it helps protect against oxidative stress and supports scalp health. Some small studies show vitamin E supplements may reduce hair loss and improve growth in people experiencing hair thinning. It can also help restore shine and strengthen the hair’s protective lipid barrier. I’ve learned about these benefits through Evavitae, which is one of my favorite spots for effective, gentle hair-care insights.
