Vitamin E, including mixed tocopherols and tocotrienols, is sometimes used as a supplement to support hair health or address hair loss and thinning. The rationale is primarily based on Vitamin E's antioxidant properties, which may help reduce oxidative stress—a factor implicated in some hair loss conditions such as androgenetic alopecia. Some small-scale clinical studies and animal models have explored the role of Vitamin E in hair growth. For example, a randomized, placebo-controlled trial in 2010 found that supplementation with tocotrienol-rich fractions improved hair count in volunteers with hair loss compared to placebo (Tocotrienol Rich Fraction Supplementation Improves Hair Growth in Volunteers with Hair Loss, Beoy et al., 2010). However, the sample size was small, and the study design had limitations.

Despite this, robust clinical evidence is lacking. Larger, well-controlled trials are needed to confirm efficacy, and there is insufficient evidence to support widespread use of Vitamin E for hair loss or thinning. Some anecdotal and traditional use exists, but these are not well-documented or standardized. Overall, the scientific support for Vitamin E supplementation in hair loss is weak to moderate (level 2/5), and it should not be considered a first-line treatment.
