Linking hair cortisol and life stress: The role of stress reactivity and habituation
The results suggest that HCC reflects not only lifetime stressor exposure but is also influenced by individual differences in cortisol reactivity, highlighting its role as an integrative, yet complex biomarker of chronic stress. In contrast, the lack of an association with habituation indicates limited sensitivity to dynamic adaptation processes occurring over weeks.
