Rating (out of 5): 3

Trace minerals, such as zinc, iron, copper, selenium, and manganese, are scientifically recognized as essential micronutrients for healthy hair growth and maintenance. Deficiencies in these minerals have been linked to various forms of hair loss, including telogen effluvium and alopecia areata. For example, zinc plays a crucial role in hair follicle recovery and DNA synthesis, while iron is necessary for proper oxygen transport to hair follicles. Several studies have found that individuals with hair loss often have lower levels of these trace elements compared to healthy controls. Supplementation can be beneficial in cases where a deficiency is present; however, evidence does not robustly support supplementation in individuals with normal trace mineral levels.

Clinical guidelines suggest checking for deficiencies in patients presenting with unexplained hair loss, particularly in women. While replenishing deficient minerals can restore hair health, excess supplementation without deficiency can be ineffective or even harmful. The overall evidence supports a role for trace minerals in supporting hair health, but primarily in the context of correcting deficiencies rather than as a general supplement for all individuals. Thus, the use of trace minerals for supporting the hair body system is justified by scientific evidence, with a moderate level of support (rating 3/5).
