Synopsis

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

Vitamin E has traditionally been used as a supplement to support hair health, particularly for hair loss or thinning. The rationale behind its use comes from its role as an antioxidant, which is thought to protect cells from oxidative stress—a factor believed to contribute to hair loss. Additionally, Vitamin E is sometimes included in topical hair oils and shampoos, based on the belief that it can improve scalp circulation and thereby promote hair growth. However, the scientific evidence supporting these claims is limited and not robust. Most studies have small sample sizes, lack strong controls, or are not replicated. A small randomized controlled trial in 2010 did suggest that tocotrienol supplementation (a form of Vitamin E) increased hair count in individuals with hair loss, but further studies are needed to confirm these findings. There is no large-scale, high-quality clinical evidence that Vitamin E supplementation or topical application provides significant benefit for hair regrowth or prevents thinning, except in cases of Vitamin E deficiency, which is rare. Overall, while its use is rooted in tradition and supported by anecdotal reports, scientific validation is weak, and more research is needed.
