This case report describes a woman with hypertension, alopecia, and other symptoms, revealing that her condition was due to ovarian hyperthecosis, highlighting the overlap of adrenal and ovarian disorders.

This case report describes a treatment approach for frontal and temporal alopecia using oral dutasteride, minoxidil lotion, and triamcinolone injections, with hyaluronic acid successfully treating injection site atrophy.

This study observed that the molecular structure of keratins in hair fibres' discrete transition zone differs in breast cancer patients, with altered lipid ester absorption bands reverting post-cancer removal.

In this report, two young patients with corticosteroid-refractory alopecia totalis experienced safety and efficacy from oral tacrolimus.

This study found that corticotropin-releasing factor influences cytokine expression related to hair growth in human dermal papilla cells and suggests CRF receptor antagonists could be potential treatments for stress-induced hair loss.

This study found that using methotrexate with corticosteroids may support hair regrowth in severe alopecia areata, but adverse effects and relapses were common, suggesting more controlled trials are needed.

This study found that certain synthetic corticosteroid and progesterone analogues inhibited hair growth in castrated male mice, with varying effects based on specific chemical modifications.

This case study reports co-localized vitiligo and alopecia areata on the scalp of a 33-year-old Indian male, with marked improvement following intralesional corticosteroid treatment, suggesting a shared autoimmune pathogenesis.

In this study, hair glucocorticoid levels, including cortisol and cortisone, showed varied associations with psychosocial stress factors, influenced by covariates like sex, age, and individual behaviors.

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.

In this study involving patients with Multiple Sclerosis, higher hair cortisol levels and being Black were linked to poorer cognitive performance, while increased perceived stress and depression were associated with greater fatigue, highlighting distinct associations between objective and subjective stress measures and MS-related outcomes.

This study observed significantly higher hair cortisol concentrations in foals compared to mares, with a strong positive correlation between the two, suggesting that hair cortisol can reflect maternal and fetal cortisol exposure during the last trimester of gestation in horses.

In this animal study, finasteride was found to significantly lower cortisol and increase testosterone levels in female rats, indicating its broader impact on endocrine regulation by altering adrenal and gonadal hormones.

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.

In this study, researchers developed a novel periodate oxidation method for extracting keratin micro-units from waste hair and feathers, achieving yields of 31.28% and 20.64% respectively, enhancing the stability of oil-in-water emulsions and suggesting potential for sustainable biomaterial production.

Lye relaxers don't significantly change hair cortisol levels.

Hair cortisol levels decrease as children age, stabilizing around age 4.

This study examines various methodological factors affecting hair cortisol concentration analysis, finding inconsistent results on the impact of factors like resuspension solution, hair weight, extraction duration, and hair-cutting method.

In this clinical trial involving 60 patients, the Fractional CO2 laser was found to be more effective in achieving significant hair regrowth in alopecia areata compared to intralesional corticosteroid injections, with a 30% absolute improvement and reduced treatment failure rates.

This study found that chemically treated hair, particularly when subjected to both acid straightening and bleaching, experiences more significant structural damage when exposed to heat, highlighting key changes in both the internal and surface components of hair fibers.

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 research review highlights how hair cortisol concentration can reflect the activation of the stress-response system in farm, domestic, and wild animals, noting it correlates with factors like species, sex, age, and environmental conditions, which may influence stress and adaptation.

This study found that generalized anxiety disorder symptoms predicted higher emotional distress and hair cortisol concentration, with dominance unexpectedly increasing the impact of anxiety on hair cortisol.

This study suggests that using combined oral contraceptives does not increase hair glucocorticoid levels, but hair treatments should be considered as a confounder in stress biomarker assessments.

This study found that cortisol levels, a biomarker of chronic stress, significantly increased in the post-COVID-19 lockdown period compared to pre-lockdown and during-lockdown periods, especially among females and young adults, reflecting sustained psychological stress from the pandemic.

Measuring cortisol in hair helps understand stress and manage related health issues.

This study found that in domestic cats, black hair contained significantly higher cortisol concentrations than white hair, whereas ginger hair showed no significant difference compared to white hair. Additionally, a positive correlation was reported between hair cortisol levels and behavioral issues mentioned by cat owners.

This case study reported a unique instance of a benign adrenal adenoma co-secreting cortisol and DHEA-S, which initially mimicked PCOS symptoms. Surgical removal resulted in significant clinical improvement, confirming the diagnosis of cyclic adrenal Cushing's syndrome.

This study found that both intralesional PRP and corticosteroids are effective for alopecia areata, but PRP offers higher patient satisfaction and fewer side effects, despite a slower initial response.

This report describes a case where a patient's rash initially treated as atopic dermatitis with topical steroids was later diagnosed as tinea incognito, an atypical dermatophyte infection that worsened due to steroid use, but was effectively treated with oral and topical antifungals.
