To determine the potential influence of hair follicles on cortisol levels, we conducted an experiment comparing cortisol concentrations in paired subsamples of brown bear hair with and without follicles. We found significantly greater cortisol values in subsamples that included follicles, suggesting that the presence of follicles may influence cortisol concentrations measured in hair. Our findings underscore the importance of standardizing hair collection and preparation methods to enable comparisons across studies.
