Synopsis

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

Alfalfa (Medicago sativa) has been traditionally used in various cultures as a natural remedy to promote general hair health. This use is largely based on its rich nutrient profile—including vitamins A, C, E, and K, as well as minerals like calcium, iron, and biotin—which are believed to support healthy hair growth. Historically, alfalfa has been incorporated into the diets of people seeking to improve hair quality, either through teas, sprouts, or supplements, under the belief that its nutritional benefits can translate to stronger, shinier hair.

However, scientific validation for alfalfa’s direct effect on hair growth or general hair care is limited. While the nutrients found in alfalfa are indeed important for overall health and some are associated with hair health when deficient, there is a lack of robust clinical evidence showing that consuming alfalfa itself leads to significant improvements in hair growth or quality. The traditional use is therefore based more on the logic of providing nutritional support for the body, rather than on targeted research into alfalfa’s effects on hair. Until more rigorous studies are conducted, alfalfa’s use in hair care should be regarded as traditional and supported by only weak evidence.
