Prevalence and Self-Reported Outcomes of Rosemary Use for Hair Care Among Adults in Saudi Arabia: A Cross-Sectional Study

A cross-sectional study conducted in Saudi Arabia surveyed 526 adults to assess the prevalence and self-reported outcomes of rosemary use for hair care. The study found that 42.8% of participants had used rosemary, with 55.7% of users reporting positive changes in hair health and 46.1% experiencing negative effects. The likelihood of reporting positive changes was higher among those aged 26–35 years, while prior use of hair loss treatments was linked to lower odds of positive outcomes. The study concludes that rosemary use is common, but its effects are mixed, highlighting the need for further research with objective clinical measures.
