This review discusses the various determinants of hair quality in healthy individuals and reports no new clinical results; the authors emphasize the need for independent trials with standardized outcomes.

In this study, researchers found that the management of alopecia areata in Poland is inadequate, despite following international guidelines, due to limited access to advanced treatments and insufficient use of severity assessments and psychosocial support.

This study evaluated the credibility of YouTube videos on exosome therapy, finding that despite promising preclinical results for wound healing, videos mostly focus on cosmetic applications and generally score low on educational quality, with doctor-made videos rating higher.

In this study, hair samples from dogs with chronic degenerative valve disease showed significantly higher concentrations of certain endocrine-disrupting chemicals compared to healthy dogs, suggesting a potential link that warrants further investigation.

This article reviews recent advancements in forensic hair testing, emphasizing its growing use for detecting past substance exposure, identifying emerging trends like micro-segmentation and hair scanning, and proposing standardized procedures to improve reliability and application in forensic toxicology.

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 developed and tested two methods to accurately quantify hair growth rates in polar, black, and grizzly bears using dye application and isotopically labelled amino acids, revealing growth rate variations by individual and season.

This study used a novel extraction method to detect and measure mineralocorticoids and glucocorticoids in hair follicles, concluding these steroids may serve as effective biomarkers for diagnosing conditions related to steroid excess or deficiency, such as Cushing’s syndrome and congenital adrenal hyperplasia.

This study examined hair follicles from 14 Caucasian males and found that catagen-phase follicles were more prevalent (7.5%) than previously reported, challenging the established view that telogen-phase follicles are more common.
