Zinc is an essential trace mineral known to play a significant role in hair health, and its deficiency has been associated with hair loss conditions such as telogen effluvium and alopecia areata. Zinc osporotate is a chelated form of zinc, intended to enhance absorption, although direct studies on zinc osporotate specifically are lacking. Most available research focuses on zinc in general, not on the osporotate form. Clinical evidence indicates that zinc supplementation can benefit individuals with hair loss related to zinc deficiency, but the benefit in individuals with normal zinc status is less clear. The scientific consensus supports the use of zinc supplementation for correcting deficiencies, which may in turn support normal hair growth. However, there is limited high-quality, controlled research specifically addressing the efficacy of zinc (and especially zinc osporotate) for hair growth in the general population. Therefore, while the underlying principle is scientifically justified, the direct evidence for zinc osporotate and its effects on hair health is not robust, warranting a moderate evidence rating.

In summary, zinc is important for hair health, and supplementation may help those with deficiency-related hair loss. However, the use of zinc osporotate in particular has not been specifically validated in clinical studies for supporting the hair body system.
