The association between alcohol consumption and AGA remains uncertain and controversial. Our primary objective is to investigate the relationship between alcohol consumption and AGA. Methods We identified studies from multiple databases, including Embase, MEDLINE, ScienceDirect, Scopus, and Web of Science, up to March 2024. For alcohol consumption, we included studies where it was defined as a categorical variable, such as Yes/No or classified by grams. For AGA, only cases that were clinically diagnosed were included. Odds ratios (ORs) and their corresponding 95% confidence intervals were extracted from the included studies. Subgroup analyses were conducted, considering factors such as gender and study design. Results Our findings indicated that individuals who consume alcohol had an OR of AGA compared to those who do not drink alcohol (OR, 1.40; 95% CI: .95？2.06; k？=？6; I2 =？77%). In the subgroup analysis focusing on men, an OR for alopecia was observed (OR, 1.31; 95% CI: .85？2.01; k？=？4; I2 =？78%). Additionally, a subgroup analysis based on study design revealed ORs of 1.93 (95% CI: 1.32？2.82; k？=？3; I2 =？47%) for cross-sectional studies, and 1.69 (95% CI: 1.33？2.14; k？=？2; I2 =？0%) for case？control studies. Conclusions Our results suggest that the effect of alcohol consumption on AGA may be less than initially assumed. Future research will require large, carefully planned cohort studies that incorporate standardized diagnostic criteria to provide more definitive insights.
