Scalp Biophysical Properties in Brazilian and English Women: A Multicenter Cross-Sectional Clinical Study

The scalp is a complex biological environment influenced by intrinsic and environmental factors, including lifestyle and hair care practices. Understanding how scalp physiology varies across anatomical regions and population groups is essential to support evidence-based, population-specific haircare strategies. Comparing populations exposed to contrasting environmental conditions can help clarify how such factors shape scalp physiology, with Brazil and England offering a valuable multicenter model for this purpose. Thus, this study aimed to compare scalp biophysical characteristics between Brazilian and English cohorts.
