This study found that the Massachusetts General Hospital Hairpulling Scale has acceptable internal consistency and divergent validity for assessing Trichotillomania severity, but demonstrated inadequate test-retest reliability and mixed convergent validity.

In this study, researchers developed innovative mechanical methods to measure the mechanical properties of Arabidopsis thaliana root hairs, concluding that axial stiffness is mainly due to tip compression and influenced by turgor pressure.

In this study, researchers developed non-invasive methods to monitor hair shaft, melanin, and collagen dynamics in C57BL/6 mice across different hair follicle cycle phases, supporting non-invasive research in hair loss treatment development.

A new computer tool quickly measures hair thickness differences in people with common types of hair loss.

This study observed that the isotope-dilution GC-MS technique can assess 5α-reductase activity more effectively than conventional methods in rat liver S9 fractions, particularly at low testosterone levels.

This study used confocal Brillouin microscopy to observe that a decrease in tissue compressibility occurs during the development and regeneration of axolotl limbs, suggesting mechanical changes linked to regeneration stages undetectable by fluorescence microscopy.

This study found that men with early-onset androgenic alopecia may be partially resistant to the cardiometabolic benefits of bromocriptine compared to those with normal hair growth.

This article reviews various diagnostic tools for hair disorders, describing methods ranging from invasive to noninvasive, but reports no new research findings or clinical results.

This study reports a less invasive method for detecting human clock gene expression using hair follicle cells, which accurately reflects individual behavioral rhythms and suggests a time lag issue for rotating shift workers.

This study suggests that simple absolute threshold monitoring rules for compliance using the biomarker DHT perform similarly to more complex methods in the Prostate Cancer Prevention Trial.

This study identifies key attributes—luminosity, structural integrity, and vitality—that define hair vibrancy, providing insights to guide the development of hair products that align with consumer expectations.

This study reports that a new DART-HRMS method can effectively analyze intact hair for drug use timelines, with cocaine detection aligning with forensic standards and identifying multiple drugs from high-resolution data.

This study introduced a novel method that uses upright structured illumination microscopy and atomic force microscopy to map the mechanical properties of thick living tissue slices, revealing the intricate mechanical heterogeneity of mouse skin and effects of preservation techniques on tissue stiffness.

Hair diameter diversity helps assess hair loss, but its standard measure varies by individual and ethnicity.

Low-dose pulsed electric fields in a rat model shifted hair follicles from resting to active growth, with voltage as the most influential factor.

A new reliable scale improves accuracy in measuring hair density and treatment response.

This study reported that pulverizing hair samples significantly improves the precision of testosterone measurement, with higher testosterone concentrations observed in men than in women.

In a pilot study with 21 patients, the niostem device increased hair counts and density and enhanced testers’ self-perception of hair growth at 6 months without reported adverse effects, suggesting potential benefits for androgenetic alopecia.

This study concluded that the best approach for detecting Androsta-1,4,6-triene-3,17-dione administration in horses is monitoring the metabolites M1b or M4 in urine, detectable up to 77 hours post-administration.

This collection from the 2021 Manfred Donike Workshop outlines advancements in doping detection, highlighting new test methods and challenges, with a focus on steroidal substances, peptide hormones, and gene doping analysis.

Using testosterone-stimulated weanling rats can effectively replace castrated rats for anti-androgen testing, reducing animal stress.
