In this study, DOP treatment improved hair regrowth in androgenetic alopecia by altering local steroid metabolism and follicular morphology.

This review highlights recent advances in chitosan-based nanoparticles (CS NPs) for drug delivery, discussing their modifications, preparation methods, production with organic and inorganic materials, and their latest implementations in the field, emphasizing the role of CS NPs in improving drug transport and release properties.

This report diagnosed a 68-year-old man with comedonal folliculotropic mycosis fungoides based on clinical and histopathological findings, and found pegylated interferon alpha-2a with isotretinoin beneficial in reducing skin lesions.

In this study, the researchers measured the specific density and dielectric permeability of human hair by analyzing the attenuation of millimeter radiowaves and accounting for multiple reflections within the hair layer.

This study reveals an antagonistic competition between BMP and Wnt signaling within stem cells, influencing their fate towards hair germ characteristics based on the BMP/Wnt activity ratio.

This study identified a novel human type I hair keratin, hHa3-II, as an isoform of a previously described hHa3 keratin, with distinct sequence differences indicating separate gene encoding.

The researchers reported that BCE-like changes overlying dermatofibroma show a differentiation pattern most similar to normal basal cells based on specific keratin markers.

In this study, certain cysteine residues in Romney sheep wool fibers were labeled more often during stretching tests, particularly under wet conditions, suggesting variability in their disulfide bond contributions to fiber mechanics depending on hydration.

This study establishes a catalog of human type I hair keratins and identifies their specific roles and expression patterns during hair differentiation and growth in scalp follicles.

This study isolated and sequenced the complete gene rKAP4L1, which encodes a cysteine-rich hair keratin-associated protein in rabbit hair follicles.

This study suggests that keratin expression in keratoacanthomas resembles that in the upper part of hair follicles, implying a potential origin, but it is indistinguishable from squamous cell carcinomas in terms of keratin reactivity.

In this study, researchers used proteomics to analyze hair samples from diverse ethnic populations, finding that hair protein profiles could potentially distinguish individuals based on ethnicity, sex, and age, offering a new method for human identification in forensic science.

Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.

Keratin structure changes during keratinization, but the exact model remains uncertain.

This study reports the development of a natural hair-coloring system using size-controlled ink particles from cuttlefish ink combined with chitosan, achieving darker and more uniform black coloration on hair than existing plant-based natural colorants, without the need for metallic mordants.

In this study, researchers evaluated the binding of keratin-associated proteins and α-keratins to human hair fibers, finding that chemical preactivation significantly enhanced binding to natural hair, while perming altered binding characteristics and increased penetration depth.

This study found that mutations in type I IRS keratin genes disrupt keratin protein complexes in mice, suggesting crucial roles for these genes in proper hair coat formation.

Keratin gene clusters in humans and marsupials are similarly organized.

This article reviews various medical treatments for hidradenitis suppurativa based on the author's experience with over 350 patients, but it reports no new clinical findings.

This study found that telogen, a resting phase of the hair follicle cycle, is characterized by dynamic gene expression, including enhanced cholesterol metabolism and immune signaling, suggesting it is an active regulatory phase despite its quiescent appearance.

This study found that nestin-expressing progenitor cells, capable of becoming ORS keratinocytes, are present in both developing and adult mouse hair follicles.

This study explored using keratin extracted from human hair waste to create biodegradable bioplastic films, revealing promising potential for applications in packaging and disposable items due to their uniform surface morphology and ability to degrade with keratinophilic fungi.

This review discusses the recent advancements in understanding how keratins influence cytoarchitecture, cell dynamics, and disease processes but reports no new clinical results; the authors highlight its roles in development and diseases like cancer.

This study discovered a new region in the hair cortex where intermediate filaments are both aligned with the hair's axis and orientationally ordered, influenced by the cuticle boundary.

This review examines recent advancements in electrospun nanofibers for wound healing applications, but reports no new experimental results, highlighting their potential in sutures, dressings, and skin regeneration.

This review discusses potential cell sources and bioengineering strategies for regenerating hair follicles with functional cycling, reporting no new results.

This study established a new cell line from human hair follicle stem cells that maintains stem cell properties and differentiation capabilities, providing a useful in vitro model for stem cell research.

This review discusses the identification and roles of different epidermal stem cell types in skin homeostasis and repair, and reports no new experimental findings.

This review found that while topical minoxidil is effective for treating female pattern hair loss, finasteride showed no more effectiveness than placebo, and low-level laser therapy increased hair count but with inconsistent results.

This study found that deleting FoxN1 in specific thymic epithelial cells disrupted the 3D thymic structure and led to age-dependent formation of 2D epithelial cysts, highlighting FoxN1's critical role in thymic morphogenesis.
