Plasma Zinc Levels in Males with Androgenetic Alopecia as Possible Predictors of Conservative Therapy Effectiveness

The study investigated the relationship between plasma zinc levels and the effectiveness of conservative therapy for androgenetic alopecia (AGA) in males. The study found that lower zinc levels in patients were associated with no effects from AGA treatment, and that an initially higher serum zinc level determined a more pronounced increase in vitamin E level. The study suggests that the concentration of zinc may be a relative criterion for predicting the effectiveness of conservative therapy, with treatment being most likely to be ineffective if the concentration of zinc is ≤ 10 µmol/L, and likely to be effective if the concentration of zinc is > 10 µmol/L. However, the study had a small number of study subjects, and further large-scale studies are needed to provide more detailed information.
