amount of cortisol embedded in hair strands over time
Hair Cortisol Concentration (HCC) refers to the amount of cortisol, a stress hormone, that is embedded in hair strands over time. Unlike blood or saliva tests that measure cortisol levels at a single point, HCC provides a long-term record of an individual's stress levels, as hair grows approximately 1 cm per month and can reflect cortisol exposure over several months. This makes it a valuable tool for both researchers and clinicians in assessing chronic stress and related health conditions.
