Conclusión

Research on zinc for androgenetic alopecia is mixed — while zinc is important for hair follicle health, supplementation alone has not been clearly shown to improve pattern hair loss.

Mixed results across 29 studies, including a meta-analysis showing inconsistent findings
Some studies find lower zinc in people with pattern hair loss, others do not
Zinc is usually studied as part of multi-ingredient formulas, making its individual contribution unclear
Supplementation may only help if a zinc deficiency is confirmed
