In this study, a new shading model for hair was developed that better matches real-life light scattering, thanks to detailed new measurements of hair fiber scattering not predicted by existing models.

This article discusses the influence of estrogens on hair follicle growth and metabolism, suggesting a significant role alongside androgens in hair growth control but reports no new clinical results.

This review discusses recent advancements in understanding and managing congenital adrenal hyperplasia, including improvements in screening, diagnostics, and potential genetic and cell-based treatments, but reports no new clinical findings.

This study found that hair follicle stem cells initially contribute to wound re-epithelialization, but long-lasting epidermal cells are primarily derived from a stem cell population in the isthmus portion of hair follicles.

This review discusses the development of an interdisciplinary guideline on Post-COVID/Long-COVID symptoms, diagnostics, and therapies by the Deutsche Gesellschaft für Pneumologie, reporting no new results but highlighting ongoing updates based on emerging knowledge.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

In a neonatal rat model, this study found that topical CDK2 inhibitors reduced chemotherapy-induced hair loss in 33 to 50% of the animals, suggesting a potential strategy for preventing alopecia in cancer patients.

This review discusses recent advances in understanding gender differences in skin and their implications for dermatologic diseases, but it reports no new experimental results; ongoing research is necessary for translating these insights into clinical practice.

This review discusses nonclassical 21-hydroxylase deficiency as the most common autosomal recessive disorder in humans and highlights the effectiveness of glucocorticoid treatment in reversing related symptoms.

This study found that 'smart' peptide hydrogels improved wound healing in a rat model of partial thickness burns, achieving greater wound closure and faster debridement compared to a standard treatment.

This guideline review by the European Dermatology Forum evaluates current treatments for androgenetic alopecia but reports no new research findings, aiming to assist dermatologists in selecting safe and effective therapies.

This review summarizes proposed pathophysiological mechanisms of postpartum depression, highlighting neuroendocrine and neurobiological changes, but reports no new findings and calls for integrated understanding of the disorder.

This review examines the role of hair follicles and sebaceous glands in percutaneous drug delivery but does not report new clinical results; it calls for further exploration of follicle-targeting therapies.

This study reviews the evolution and modifications of microneedle drug delivery systems, initially designed for percutaneous use, now expanded for targeting a variety of tissues and organs such as ocular, oral mucosal, and gastrointestinal, suggesting widespread future applicability.

This article discusses the structure of hair follicles and their significance in evaluating hair disorders, but it does not report any new research findings.

This study found that subcutaneous administration of conditioned medium from adipose-derived stem cells promoted hair growth in mice, and hypoxia enhanced this effect by altering growth factor secretion.

This review discusses recent findings on the plasticity and regulation of epithelial stem cells and reports no new experimental results.

The study found that prolactin expressed in human scalp hair follicles acts as an autocrine modulator, inhibiting hair growth and promoting hair follicle regression, which may contribute to hair loss in hyper-prolactinemia patients.

This study supports the conclusion that the hormetic dose-response model is the most prevalent and fundamental model in biological and biomedical sciences, applicable to a wide range of clinical conditions.

This review examines regenerative hair waves and complex hair cycle domains in transgenic mice, highlighting how these dynamic processes contribute to skin regeneration and the physiological regulation of organs, but reports no new experimental results.

This article reviews the classification of hair shaft abnormalities, outlining their diagnostic features, but does not present new research findings.

This review summarizes recent advances in Treg cell biology, focusing on Foxp3's role in immune regulation and therapeutic reprogramming for immune dysregulatory disorders, but reports no new clinical results.

This review covers recent findings on stem cell plasticity under normal and cancerous conditions but presents no new experimental results, highlighting implications for regenerative medicine and cancer treatments.

This review discusses the role of the JAK-STAT pathway in autoimmune skin diseases and suggests potential therapeutic benefits of JAK inhibitors, but reports no new experimental results.

This review discusses the roles of androgens and androgen receptors in skin-related disorders and suggests that targeting androgen receptors may be a more effective treatment strategy.

Diffuse alopecia in women may be related to androgens and iron deficiency, and basic hormone and nutrient screening is useful.

Minoxidil can help grow hair in mice by making cells grow and improving hair quality. More research needed.

This article explores the dynamic and energy-efficient nature of telogen hair follicles, challenging the notion of dormancy, and highlights their potential in advancing treatments for hair growth disorders.
