Glossary Hair Cortisol

measurement of stress hormone levels accumulated in hair strands

Hair cortisol refers to the measurement of cortisol, a stress hormone, that is accumulated in hair strands over time. This method provides a long-term indicator of an individual's stress levels, as opposed to blood or saliva tests which only capture short-term fluctuations. It is particularly useful in research and clinical settings for assessing chronic stress and its potential impacts on health.
