What is the best sampling region for endocrine hair analysis? A comparison between the posterior vertex and occipital region and recommendation for standardization
Our findings highlight the importance of sampling from a defined scalp region for endocrine hair analyses. While neither scalp region was unequivocally superior, differences in mean concentrations call for increased standardization of methodological practice in future research. We propose anatomical landmarks for precise region localization and offer practical recommendations concerning the choice of sampling region.
