Analysis of Hair Loss Status and Influencing Factors Among Undergraduate Students

Purpose This study aims to investigate the prevalence of hair loss among undergraduate students and analyze the influencing factors, thus providing a scientific basis for effective prevention and treatment strategies. Methods A cross-sectional survey was conducted among 3,052 college students from 20 provinces using the Questionnaire Star platform. Three validated scales were employed: the Hair Loss Grading Scale, the Pittsburgh Sleep Quality Index (PSQI), and the Depression, Anxiety and Stress Scale-21 (DASS-21). A binomial logistic regression model was used to analyze the influencing factors of hair loss. Results Among the participants, 39.2% (n = 1,186) reported hair loss, with 91.5% (n = 1,085) experiencing mild hair loss and 8.5% (n = 101) experiencing moderate to severe hair loss. Female students (OR = 12.130, 95% CI = 9.366–15.709), those with a family history of hair loss (OR = 1.809, 95% CI = 1.493–2.192), scalp itching (OR = 2.257, 95% CI = 1.432–3.556), oily hair (OR = 1.300, 95% CI = 1.022–1.654), sleep disorders (OR = 1.371, 95% CI = 1.126–1.670), and depression (OR = 1.406, 95% CI = 1.050–1.881) were identified as significant risk factors for hair loss (P < 0.05). Conclusion Hair loss is prevalent among undergraduate students, with most cases being mild. Universities and health authorities should implement regular health education programs on hair loss prevention and promote healthy lifestyles among students.
