Sesame oil has a long history of traditional use for supporting hair health, particularly in Ayurvedic and traditional Chinese medicine. It is commonly applied topically to the scalp and hair to promote strength, luster, and overall hair vitality. The oil is thought to nourish the scalp, reduce dryness, and possibly help with issues such as dandruff. Some traditional practices also claim that sesame oil can prevent premature graying and hair loss, though these claims are not substantiated by robust clinical evidence.

Scientifically, there is limited direct research specifically evaluating sesame oil’s effects on hair growth or hair loss in humans. Sesame oil does contain nutrients such as vitamin E, B-complex vitamins, and minerals, and it has antioxidant and anti-inflammatory properties when used on the skin. Some laboratory and animal studies suggest these properties may contribute to scalp health, which could indirectly support hair health. However, robust clinical trials in humans are lacking.

In summary, the use of sesame oil for hair care is primarily justified by traditional practices, with some plausible mechanisms based on its nutrient and antioxidant content. However, scientific validation remains limited, and more research is needed to confirm its efficacy for supporting the hair body system.
