Royal jelly, a secretion produced by honeybees, has been traditionally used in various cultures for its purported health and cosmetic benefits, including the support of hair health and the prevention of hair loss or thinning. In traditional medicine systems, especially in East Asia, royal jelly has been consumed orally or applied topically as a natural remedy to enhance hair strength, promote hair growth, and improve scalp health. The rationale is largely based on its rich composition, including proteins, vitamins (notably B vitamins), fatty acids, and trace minerals, which are believed to nourish hair follicles and stimulate growth.

Scientific evidence supporting royal jelly’s efficacy for hair loss or thinning is limited and primarily consists of in vitro and animal studies. Some small studies suggest that royal jelly may promote hair growth by enhancing keratinocyte proliferation or by reducing inflammation in the scalp. For example, a 2012 study in mice showed that royal jelly supplementation increased the number of hair follicles in the anagen (growth) phase. However, robust clinical trials in humans are lacking, and the mechanism of action remains speculative.

Overall, while royal jelly has a historical tradition of use for hair health and some preliminary evidence from animal models, there is insufficient scientific validation to recommend it as an effective treatment for hair loss or thinning. Its use for this purpose remains primarily grounded in traditional practice rather than in strong clinical evidence.
