Evaluation of the severity and triggering factors of sensitive scalp in Chinese females

Background Sensitive scalp which has been recently proposed and assessed by several questionnaires is one of the most cosmetic concerns in sensitive skin syndrome by consumers. Objective This study is to investigate the prevalence and factors related to the scalp sensitivity in China. Methods Two well-known questionnaires including four-grade self-assessment and 3S, and a new questionnaire we proposed (10Q), were used to evaluate the severity and symptoms of sensitive scalp. Results The proportions of sensitive scalp according to self-assessment and 3S were 35.77% and 57.45%, respectively. Distributions of severity and tendency of proportion along ages were significantly different between the two methods. The 10Q questionnaire which we designed could discriminate different grade of severity of sensitive scalp with superior reliability. Moreover, triggering factors which have significant impacts on the symptoms of sensitive scalp were elucidated by logistic regression analysis, including air dryness, exercises, humidity, heat, and sun. Conclusion Questionnaires with more dimensions and details such as 10Q and 3S should be used for the diagnosis, prognosis, and treatment monitoring on sensitive scalp in Chinese female.
