Investigation of Exacerbating Factors for Postpartum Hair Loss: A Questionnaire-Based Cross-Sectional Study

This study examined postpartum hair loss in 331 women, finding that 91.8% experienced hair loss, with anxiety or stress reported by 73.1%. Hair loss typically began around 2.9 months postpartum, peaking at 5.1 months and ending by 8.1 months. The duration of breastfeeding was identified as an independent predictor, with women breastfeeding for 6-12 months having an odds ratio of 5.96 and those breastfeeding for more than 12 months having an odds ratio of 6.37 for experiencing hair loss. The study suggests that postpartum hair loss may be influenced by estrogen levels and inflammation, with breastfeeding affecting hormonal cycles. Awareness of these factors could help manage expectations and anxiety, though further research is needed to explore hormonal influences and the potential role of formula feeding.
