This summary presents papers from the British Society for Dermatopathology but does not report new scientific findings or results.

This study found that DNA strand segregation in multipotent hair follicle stem cells occurs randomly during development and tissue homeostasis, challenging the immortal strand hypothesis.

This study found that metabolite levels in hair samples differ significantly by hair color and segment, leading to recommendations for best practices in hair metabolomic studies.

In this study, researchers developed a regression model that reasonably predicts consumer-perceived hair breakage using various parameters such as hair smoothness, detangling forces, extensional strength, and hair density among Indian women.

This study found that methylcellulose-based hydrogels can effectively deliver growth hormone through the skin, with albumin increasing the hormone's permeation to 93% in simulated in vivo conditions.

This study found that Mueller-Hinton Agar performed better than Dermasel Agar for antifungal susceptibility testing of feline dermatophytes, providing reliable susceptibility data for effective antifungal therapy.

This article reviews strategies for serological testing in diagnosing ILD linked to systemic rheumatic diseases and introduces a potential diagnostic algorithm for pulmonologists, while noting further validation is needed.

This study found that cosmetic hair treatments like bleaching and dyeing significantly reduced drug concentrations in hair samples, with decreases ranging from 30% to over 60% depending on the treatment and hair damage level.

This study found that different decontamination protocols caused varying levels of cuticle damage in hair, with aqueous buffer treatment resulting in the most substantial degradation.

This study found that organoid cultures of human epithelial and mesenchymal cells can produce hair peg-like structures, and their growth is enhanced by minoxidil, suggesting potential for hair drug screening.

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 introduced a multitask learning method to identify shortcut learning in clinical ML systems, revealing it's not always responsible for unfairness and emphasizing the necessity of comprehensive fairness approaches in medical AI.

This review discusses the increasing importance of hair analysis in forensic toxicology and highlights the complexities in interpreting results due to external contamination and regional collection differences, but reports no new findings.

This review covers the molecular basis of Birt–Hogg–Dubé syndrome and its implications for potential therapeutic targets, but it does not report new experimental results.

This study found that keratin intermediate filaments in the hair of GAN patients are altered, showing decreased diffraction signals and increased stiffness, strength, and extensibility.

Genetic testing for hairless gene mutations is crucial to correctly diagnose and treat atrichia with papular lesions.

This review describes how liver and kidney diseases and diabetes may affect ethyl glucuronide levels in hair, impacting forensic and clinical interpretations, but reports no new experimental results.

This study found that DNA-damaged hair follicle stem cells in mouse models do not show typical senescent markers but are dynamically expelled to maintain tissue health and prevent hair loss.

These guidelines recommend testing thyroid function in patients with obesity due to common hypothyroidism, and highlight that weight loss is crucial for addressing hormonal imbalances, with only modest weight loss benefits from treating endocrine disorders.

This review discusses the current state of research on skin organoids, highlighting their potential for replicating complex skin structures and comparing recent studies on stem cell microenvironments.

This study resulted in a draft version of the Patient‐Reported Impact of Dermatological Diseases measure, PRIDD, which includes 27 items refined from patient consensus and is now undergoing psychometric testing.

This source outlines Roota Hair Growth Serum® as a premium product combining natural ingredients and scientific research to target hair thinning and promote scalp health, claiming a positive impact on hair regrowth when used consistently over time.

This article discusses the impact of COVID-19 on various sectors and reports no new clinical findings.

Innovative methods are reducing animal testing and improving biomedical research.

This study developed a new method using liquid chromatography-tandem mass spectrometry to measure multiple steroid hormones in hair, requiring significantly fewer strands than previous methods, with high accuracy and precision.

This review discusses various forensic applications of hair analysis, such as species identification and drug addiction testing, and reports no new study results.

This review discusses various substances that can impact male fertility and stresses that products should be confirmed 'sperm-safe' through rigorous testing, not assumptions; it reports no new study results.

This study found that ionizing irradiation significantly inhibits proliferation and induces apoptosis in human hair follicle keratinocytes, suggesting its potential as a preclinical assay system for testing radioprotectants.

This study identified 30 new compounds with significant androgen receptor binding affinity through a combination of virtual screening and in vitro testing.

This study reported that a 3D-printed LED photobiomodulation device is technically and financially feasible, but requires further experimental and clinical testing before being used in human healthcare.
