Fulvic acid has a long history of use in traditional medicine systems, particularly within Ayurveda and certain folk remedies. In these traditions, fulvic acid—often derived from shilajit or humic substances—has been used to promote general vitality, including claims regarding improved hair health and reduced hair loss. The traditional rationale is that fulvic acid may help deliver minerals and nutrients to the scalp and hair follicles, thereby supporting growth and reducing shedding.

However, scientific studies directly investigating the efficacy of fulvic acid for hair loss or thinning are limited. Some laboratory and animal research suggests that fulvic acid may have antioxidant, anti-inflammatory, and nutrient-transporting properties, which could theoretically benefit scalp health and thus hair growth. One small clinical study (2011) showed that a topical solution containing fulvic acid led to subjective improvement in hair condition, but the sample size was limited and methodology was not robust.

Overall, while fulvic acid is traditionally used for hair health and there is some plausibility to its biological mechanisms, high-quality clinical evidence is lacking. Most support for its use comes from traditional practices rather than rigorous scientific validation. Further research is needed to establish its effectiveness for hair loss or thinning.
