hair cortisol cortisol stability cortisol variability stress monitoring cortisol concentrations

Studysummary This study found that while the reproducibility of hair cortisol measurements in captive chimpanzees was high, the fineness of homogenized hair, sample weight, and extraction time influenced absolute cortisol concentrations.

Hair as a Retrospective Calendar of Cortisol Production—Increased Cortisol Incorporation into Hair in the Third Trimester of Pregnancy

research Hair as a Retrospective Calendar of Cortisol Production—Increased Cortisol Incorporation into Hair in the Third Trimester of Pregnancy

501 citations , October 2008 in “Psychoneuroendocrinology”

This study suggests that cortisol measured in human hair can effectively reflect increased production for up to six months, but its retrospective accuracy may be limited due to rapid decline in levels.

research Cortisol Determination in Hair and Feces from Domestic Cats and Dogs

199 citations , July 2007 in “General and Comparative Endocrinology”

In this study, researchers found a significant positive association between cortisol levels in hair and feces of domestic cats and dogs, suggesting hair cortisol assays could be a viable option for monitoring chronic stress.
