This study found that mechanical skin stretching can stimulate hair stem cell proliferation and hair regeneration by activating a complex pathway involving WNT, BMP-2, and M2 macrophages.

This study found that women with androgenetic alopecia or alopecia areata have significantly lower serum ferritin levels than those without hair loss, suggesting a potential link between these types of alopecia and decreased iron stores.

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.

This study found that keratin K14 expression occurs early in epidermal cell differentiation, while a hair-specific keratin is expressed later in hair matrix cells, suggesting developmental divergence between the two cell types.

This extensive review discusses the clinical manifestations, potential associations, and treatment approaches for lichen planus, but reports no new clinical results, highlighting gaps in evidence for therapeutic strategies.

This review explores the causes and mechanisms of alopecia areata and discusses current treatments, reporting no new clinical findings.

This review discusses genetic and environmental factors contributing to autoimmunity in alopecia areata and reports no new clinical findings, emphasizing the need for further study on its aetiology and pathophysiology.

This review discusses various forms of ichthyosis, including genetic and acquired types, detailing their characteristics, causes, and potential management strategies, but reports no new clinical results.

This study identified a new type II cytokeratin, named K6hf, exclusively expressed in the companion layer of the human hair follicle, distinguishing it from other keratins and suggesting a unique biochemical role.

Inflammation may be linked to hair loss, and targeting specific enzymes could help treat it.
