30-60 / 1000+ resultsresearch Hair Cortisol Concentrations Are Associated with Hair Growth Rate
Hair cortisol levels can indicate stress over the past three months.
research Do follicles matter? Testing the effect of follicles on hair cortisol levels
Hair follicles increase hair cortisol levels, so consistent hair collection methods are important.
research Comparison of methanol and isopropanol as wash solvents for determination of hair cortisol concentration in grizzly bears and polar bears
Methanol is better than isopropanol for washing grizzly bear hair to measure cortisol.
research Is it getting in the hair? – Cortisol concentrations in native, regrown and segmented hairs of cattle and pigs after repeated ACTH administrations
Hair cortisol is a reliable stress indicator in cattle but may not be valid for pigs.
research Analysis of Hair Cortisol as an Indicator of Chronic Stress in Pigs in Two Different Farrowing Systems
Pigs in farrowing crates and loose-housing systems showed no difference in chronic stress levels as measured by hair cortisol.
research Study on dissolution mechanism of cortisol and cortisone from hair matrix with liquid chromatography–tandem mass spectrometry
Cortisol and cortisone release from hair increases in steps over time during incubation.
research Not the Root of the Problem—Hair Cortisol and Cortisone Do Not Mediate the Effect of Child Maltreatment on Body Mass Index
Child abuse is linked to higher BMI, but not because of hair cortisol or cortisone levels.
research Use of hair cortisol as a biomarker for chronic stress in pregnancy
Hair cortisol could be a marker for chronic stress in pregnancy, but depression affects cortisol levels differently.
research Temporary Relocation during Rest Periods: Relocation Stress and Other Factors Influence Hair Cortisol Concentrations in Horses
Moving horses to new places can increase their stress levels, as shown by higher stress hormone in their hair.
research Children’s hair cortisol as a biomarker of stress at school: a follow-up study
Children with lower inhibitory control experience more stress when starting third grade.
research Hair cortisol and other hair analytes decline with storage over a one-year period: A systematic, within-subject investigation
Hair analytes decrease with storage, so analyze within six months.
research Cortisol levels in blood and hair of unanesthetized grizzly bears (Ursus arctos) following intravenous cosyntropin injection
Injecting cosyntropin into grizzly bears increases blood cortisol but doesn't change hair cortisol levels.
research Exploring Reference Values for Hair Cortisol
Hair sample weight is a better measure for cortisol levels in hair than hair protein concentration.
research Relationship of Hair Cortisol Concentration With Perceived and Somatic Stress Indices: Cross-Sectional Pilot Study
Hair cortisol concentration may reflect some physiological stress but doesn't strongly correlate with perceived stress.
research Children’s hair cortisol and hair testosterone concentrations in response to environmental changes: from summer holidays to school
Girls had higher stress hormone levels during school due to social and emotional issues, while boys had higher overall hormone levels with slight changes when school started.
research Evidence of the moderating role of hair cortisol and hair cortisone in the relationship between work stress and depression symptoms among Chinese fishermen
Hair cortisol and cortisone levels may affect how work stress influences depression in Chinese fishermen.
research Methodological Challenges and Clinical Applications of Hair Cortisol Analysis
Hair cortisol analysis shows sweat affects cortisol levels, and severe OSA may increase stress, but CPAP treatment doesn't significantly reduce physiological stress.
research Hair cortisol in polycystic ovary syndrome
Women with PCOS have higher hair cortisol levels, which are linked to worse metabolic and inflammatory conditions.
research Scalp hair sweating as a predictor of hair cortisol level in human compared to obesity and other confounders
Scalp hair sweating is a significant predictor of hair cortisol levels.
research Correlation between high hair cortisol level and intracranial aneurysm rupture
High levels of cortisol in hair are linked to a greater risk of brain aneurysm rupture.

The procedure reliably measures cortisol in rhesus macaque hair.
research Longitudinal association between saliva and hair cortisol concentration: A systematic comparison
Hair cortisol is a reliable marker of long-term cortisol levels and is linked to daytime saliva cortisol but not morning levels.

Childhood sexual trauma, especially between ages 5-7, is linked to lower cortisol levels in adult hair, suggesting long-term stress response changes.
research Trends in Hair Cortisol from Preconception to the Postpartum Period
Hair cortisol levels peak in the third trimester and decline postpartum.
research Hair cortisol: What we know and what we don’t (yet)

research Beyond Perceived Stress: Hair Cortisol is linked with Cognition and Fatigue in Black and White Patients with Multiple Sclerosis
Higher cortisol levels and stress are linked to worse cognition and more fatigue in MS patients.
research From lifetime stressor exposure to daily stress experience: Associations with hair cortisol
Hair cortisol levels may be linked to stress, but results are inconsistent.
research Does hair cortisol mediate the effects of sexual and gender minority stress on depression and anxiety? A structural equation modelling approach
Gender-diverse individuals face more depression and anxiety, possibly due to unique stress profiles.
