Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Vitamin E (alpha-tocopherol acetate) is traditionally used as a supplement to support hair health and address hair loss or thinning. The rationale is based primarily on its antioxidant properties, which are believed to help protect scalp and hair follicle cells from oxidative stress. Historically, vitamin E has been included in hair oils, shampoos, and supplements with the claim that it promotes hair growth, improves scalp circulation, and reduces hair fall. However, the scientific evidence supporting these claims is limited and of low quality. Most available research consists of small-scale studies, anecdotal reports, or studies combining vitamin E with other nutrients, making it difficult to attribute benefits specifically to vitamin E. For example, a small 2010 study found that a tocotrienol (a form of vitamin E) supplement increased hair numbers in people with hair loss, but the sample size was small and results have not been widely replicated. No large, high-quality randomized controlled trials have definitively shown that vitamin E supplementation alone significantly improves hair loss or thinning. Overall, while the use of vitamin E for hair health is widespread in traditional and commercial products, robust scientific validation is lacking.
