A transversal case-control study involving 42 patients with diffuse alopecia and 230 matched controls without hair and nail disorders evaluated the role of dietary intake in alopecia. Nutrient intake was assessed using a 3-day dietary method and analyzed with SPSS software. The study found that only protein intake was directly associated with alopecia, with an odds ratio of 1.5 (1.06 - 2.3) and a p-value of 0.02, suggesting that higher protein intake might be linked to the occurrence of alopecia.
