Synopsis

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

Alfalfa (Medicago sativa) has traditionally been used in herbal medicine for a variety of purposes, including as a general health tonic. Its use for hair loss or thinning is primarily rooted in traditional and folk practices, not in scientific validation. Historically, alfalfa has been valued for its rich nutrient profile, including vitamins (such as vitamin K, vitamin C, and some B vitamins), minerals (like iron, calcium, and magnesium), and phytoestrogens. Proponents of traditional remedies have suggested that these nutrients may help support hair growth and overall hair health by improving nutritional status.

However, direct evidence supporting the effectiveness of alfalfa specifically for treating hair loss or thinning is lacking. There are no high-quality clinical studies demonstrating that alfalfa supplementation can prevent or reverse hair loss. Any observed benefits are likely attributable to its general nutritional value rather than any unique or targeted effect on hair follicles. Thus, while alfalfa may play a role in supporting general health—potentially benefiting hair as part of an overall nutrient-rich diet—the traditional use for hair loss is not strongly supported by scientific research. The evidence rating is therefore low, reflecting the gap between traditional claims and scientific validation.
