,
October 2020 in “Therapeutic drug monitoring” In this study, researchers found that targeting a tacrolimus trough level of 4–7 ng/mL after liver transplantation resulted in comparable graft and patient survival rates to higher levels, while improving liver and kidney function markers.
5 citations
,
June 2020 in “Therapeutic drug monitoring” This study found that hair sample weight was a better predictor of hair cortisol concentration than hair protein concentration, suggesting that using the standard cortisol-to-weight ratio is more suitable for measuring cumulative cortisol activity in scalp hair.
11 citations
,
May 2020 in “Frontiers in psychiatry” This study found that experiencing childhood abuse is associated with higher BMI, but hair cortisol and cortisone do not mediate this relationship.
16 citations
,
May 2020 in “Psychoneuroendocrinology” This study observed that Parkinson’s disease patients had higher hair cortisone, but not cortisol, levels compared to controls, and cortisone was significantly associated with mood-related non-motor symptoms.
24 citations
,
January 2019 in “Hormone Research in Paediatrics” This study found that gender, puberty, and BMI significantly affect hair cortisol concentrations in children, suggesting these factors should be considered in future research.
12 citations

November 2018 in “Developmental Psychobiology” In this study, testosterone and dehydroepiandrosterone in children's hair were strongly correlated, supporting hair as a potential method for measuring these hormones.
237 citations
,
September 2018 in “Clinical Biochemistry” Hair cortisol analysis can help diagnose stress-related conditions but needs more refinement for widespread use.
22 citations
,
August 2016 in “European Eating Disorders Review” This study found that female patients with anorexia nervosa had lower hair cortisol concentration compared to healthy and psychiatric controls, which may be influenced by body mass index rather than anorexia-related endocrine changes.
157 citations
,
June 2015 in “Psychoneuroendocrinology” This study observed that hair cortisol and cortisone concentrations were higher in older individuals and those with diabetes mellitus, highlighting their potential significance for assessing somatic health.
50 citations
,
June 2014 in “Experimental and Clinical Endocrinology & Diabetes” This study found that hair cortisol levels increase and testosterone levels decrease with obesity, suggesting that measuring hormones in hair may be a valuable tool in obesity research and clinical practice.
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.
