This study concluded that fractional laser therapy, alone or combined with minoxidil or cortisol, effectively treated alopecia areata, showing better outcomes than the drugs alone, without increasing adverse effects, though effectiveness did not significantly differ from similar physical treatments.

This study developed a method to measure local steroid hormone concentrations in hair, providing new insights into hormone dynamics associated with androgenetic alopecia.

This study developed a validated method using UPLC-MS/MS to analyze 37 hormones in human hair, enabling broader hormonal profiling for identifying endocrine disorders.

This study evaluated factors influencing hair steroid concentrations in early infancy, finding small effects from birth mode, season, and age-related changes, suggesting hair analysis as promising for assessing long-term endocrine activity.

This study suggests that potent topical corticosteroid occlusion may be a safe and effective treatment option for pediatric patients with severe alopecia areata, although further research is needed on its long-term safety and recurrence.

This study suggests that collecting hair samples from all scalp regions may be a viable alternative for measuring cortisol in individuals with Afro-textured or extremely short hair, aligning results with traditional methods.

This study is designed to explore how circadian rhythms are affected by obesity and mental health conditions, such as schizophrenia and bipolar disorder, using biological and lifestyle data from independently living adults.

This review discusses the use of hair analysis for examining stress and reproduction hormone levels in wildlife and highlights the need for more comprehensive physiological validations across species.

This study found that hair steroid profiling is a feasible, non-invasive alternative to serum analysis in adolescents, with androgen levels correlating more strongly with body size and composition in boys than girls.

This study compared serum and hair steroid hormone profiles in adolescents and found that hair steroid profiling is a feasible, non-invasive alternative to serum analysis, with androgen levels in both mediums correlating more strongly with body size and composition in boys than in girls.

This study found that among Japanese full-time employees, cortisol levels in hair were negatively associated with aversive coping and emotional support-seeking tendencies, while dehydroepiandrosterone levels were linked to job confidence.

This study documented that symmetrical, noninflammatory alopecia in schipperkes is associated with hormonal abnormalities and hair cycle arrest, resembling Alopecia X clinically and histologically.

This study found that collecting hair samples for cortisol analysis is feasible in community-dwelling individuals with longstanding multiple sclerosis, although no significant correlation between hair cortisol levels and perceived chronic stress was observed, highlighting the complexity of stress measurement in this population.

This study demonstrated that cortisol, estradiol, and testosterone are preserved in archaeological human hair, allowing for the analysis of ancient stress and reproductive hormone patterns.

In this study, researchers found that storing hair samples for over 12 months significantly lowers the concentrations of important analytes such as cortisol and cortisone, recommending analyses within six months to ensure data quality.

This study found that hair steroid analysis effectively detected increased hormone levels from both a single testosterone dose and laboratory-induced stress, revealing individual context factors like relationship status also impact hair hormone concentrations.

This study found that hair cortisol concentrations are a more reliable biomarker of long-term stress during pregnancy in Akkeçi goats compared to serum cortisol levels, with significant differences observed in hair matrix period means.

Lye relaxers don't significantly change hair cortisol levels.

This study presents a new LC-MS/MS method that allows for more accurate detection of seven steroid hormones in human hair, enhancing the specificity and reliability of hormone analysis in psychoneuroendocrinological research.

This study found that cortisol concentrations were significantly higher in hair samples with follicles compared to those without, suggesting potential confounding in stress assessments using different hair sampling methods.

This study found that higher hair cortisol concentrations, indicating chronic stress, were associated with an increased risk of aneurysmal rupture in patients with intracranial aneurysms.

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.

In this study, testosterone and dehydroepiandrosterone in children's hair were strongly correlated, supporting hair as a potential method for measuring these hormones.

In this study, prolonged intravenous Fenoterol infusion was associated with intensive hair growth in most patients, although hormonal changes typically linked to such effects were not observed.

This study found that manipulating maternal cortisol levels during pregnancy altered Merino sheep wool characteristics, increasing fibre length and reducing crimp frequency in the offspring.

This study found that while pulverization yielded slightly higher hair cortisol extraction, the significant interindividual differences observed suggest that any of the methods could be used effectively.

This study found that women undergoing mid-trimester termination of pregnancy exhibited increased cumulative cortisol and testosterone levels in hair samples, higher anxiety, but better stress coping strategies two months post-abortion, suggesting hair testosterone may be linked to emotional vulnerability such as neuroticism during this period.

This study found that a hair growth rate of 0.75 cm/month better matches retrospective cortisol timelines and identified factors influencing hair cortisol content in children and adolescents.

In this study, researchers observed a curvilinear relationship between loneliness and hair cortisol concentration among older adults at elevated cardiovascular risk, with cortisol levels higher at low-to-moderate loneliness and lower at higher loneliness, though results were sensitive to some data exclusions.

This study found that in lactating Holstein cows, hair from the tail switch, which grows faster and is more sensitive to cortisol changes, is ideal for measuring hair cortisol levels.
