A gene called APCDD1, which controls hair growth, is found to be faulty in a type of hair loss called hereditary hypotrichosis simplex.

This review discusses advances in understanding hair and hair follicle structure, gene expression, and molecular signals in hair formation, without reporting new clinical findings.

This review discusses the role of regulatory T-cells in tissue repair and regeneration across various organs and reports no new clinical results.

This review discusses strategies for developing semi-solid topical generic products to match the quality of reference-listed drugs, using concepts like quality by design and reverse-engineering, but reports no new results.

This article reviews current and emerging treatments for alopecia areata, including Janus kinase inhibitors, highlighting variability in clinical outcomes and the lack of sustained remission.

These guidelines for alopecia areata management, prepared by the British Association of Dermatologists, provide evidence-based treatment recommendations and insights into the condition's epidemiology, diagnosis, and investigation.

This study suggests that ethylene and lignoceric acid (C24:0) may promote cotton fiber and Arabidopsis root hair growth by activating the pectin biosynthesis network.

This study found that chitosan nanofibrillar scaffolds accelerated skin wound healing in mice by enhancing cell adhesion, proliferation, and regeneration of epidermis and dermis compared to other forms.

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 study found that different stabilizing mutations in Aux/IAA proteins affect root hair development in Arabidopsis by disrupting the auxin response and suggest a model where the relative abundance of these proteins determines root hair initiation.

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.
