Studysummary This study found that wolves in heavily hunted areas of Canada's tundra–taiga exhibited higher levels of stress and reproductive hormones, indicating social instability and increased reproductive effort due to human-caused mortality.

This study found that wolves in heavily hunted areas of Canada's tundra–taiga exhibited higher levels of stress and reproductive hormones, indicating social instability and increased reproductive effort due to human-caused mortality.

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 Measurement of Cortisol in Human Hair as a Biomarker of Systemic Exposure

567 citations , October 2007 in “Clinical and investigative medicine”

This study described a new assay for measuring cortisol in hair and found it may serve as a useful biomarker for long-term cortisol exposure, correlating with 24-hour urine cortisol levels in non-obese subjects.

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.

research Human Hair Follicles Display a Functional Equivalent of the Hypothalamic-Pituitary-Adrenal (HPA) Axis and Synthesize Cortisol

489 citations , June 2005 in “The FASEB Journal”

This study found that human scalp hair follicles can respond to corticotropin releasing hormone stimulation similarly to the classical HPA axis, including up-regulating cortisol production and activating neuroendocrine feedback loops.
