This study identified two types of hard alpha-keratin filament assemblies in developing human hair follicles, which may help investigate the structural framework of mammalian keratin appendages.

This article reviews the indications for micropigmentation in dermatological conditions like stable vitiligo and alopecia, but presents no new clinical results.

A new mutation, Glu402Lys, in hair keratin is linked to variable symptoms of monilethrix.

This study evaluated skin and hair color variations in different mouse strains, highlighting the association between hair cycle stages and skin pigmentation to better understand these features and their implications.

This study found that differences in skin transcriptomes between juvenile and adult mink, as well as between black and white mink, suggest genes regulating hair color are active during early development rather than adulthood.

This study found that Ber-EP4 immunoreactivity is present in specific areas of hair follicles across different stages of the hair cycle, particularly in the secondary hair germ, but not in mature anagen follicles.

In this study, researchers found that a PER3 gene SNP may be pathogenic for a new subtype of dyschromatosis universalis hereditaria, especially when combined with a SASH1 mutation.

This study found that after 24 weeks of DPCP treatment for alopecia areata, there was a significant increase in new capillaries and hair regrowth detectable by videocapillaroscopy.

This study revealed that during fetal development, MITF and Mart-1 expressing melanocytes progress from the dermis to the epidermis and hair follicles, with MITF possibly marking follicular stem cells.

In this study, researchers observed distinct morphological differences in hair follicles of mutant mouse genotypes, influenced by the expression levels of keratin2-6g, which is essential for proper hair follicle development.

This study reports that melanocytes form a defined photoresponsive network in the skin that reads environmental light cycles and may influence the sleep-waking cycle similar to the pineal gland.

This review discusses the genetic disorder, monilethrix, characterized by fragile, brittle hair and its inheritance patterns, and reports no new clinical results.

This case report describes a 22-year-old woman with a nevoid plaque termed localized follicular hamartoma, characterized by skin-colored papules and specific cellular and structural features.

This study found that Sox2 and BMP signaling may be key regulators of pigmentation and melanocyte migration, as suggested by experiments in mice, human biopsies, and cell co-cultures.

This study observed that different hair types on Tianzhu white yaks have similar ultrastructures, but coarse hair fibers show distinct structural differences across body parts.

In this study, researchers found that the peripilar sign in patients with androgenetic alopecia does not indicate perifollicular infiltrate but is more frequent in individuals with lighter skin types due to contrast with the skin.

This study describes unique anatomical characteristics of the skin and hair structures in the silver marmoset, including features such as thin epidermis, specialized nerve end-organs, and distinctive gland compositions.

This study reports a case of GGCX syndrome in a 55-year-old Japanese male, characterized by PXE-like symptoms and coagulation deficiency, with an unreported phenotype of possible spinocerebellar degeneration.

This report describes a case where solar-induced postinflammatory hyperpigmentation following laser hair removal was treated with a combination of topical treatments and serial TCA peels, resulting in only slight improvement.

This study used fibre optic confocal imaging to visualize subsurface structures in live mouse skin, revealing cellular details and blood vessel networks that dynamic events could be studied in vivo.

This study used phase contrast hard x-ray microscopy to capture detailed images of healthy human hair, revealing distinct structures such as the medulla, cortex, and cuticular layer.

This study found that in anagen hair follicles, the basement membrane zone components showed decreased expression in the lower hair bulb, with a complete absence of BP230 at the dermal papilla junction, suggesting an incomplete hemidesmosome structure in these regions.

This study found that 1,2,3,4-tetrahydroquinoline derivatives, particularly N-methyl-7-amino-1,2,3,4-tetrahydroquinoline, may be excellent blue dye candidates for human hair, offering superior color purity, stability, and fastness compared to 2,3-dihydroindoles.

This study identified the distribution of keratin-associated proteins during cornification in the epidermis of reptiles, revealing unique structural characteristics in sauropsid keratin proteins compared to other vertebrates.

Hard α-keratin in hair has a unique, nonordered structure, different from other fibers.

This study found that contrast enhanced phototrichogram (CE-PTG) significantly improved detection of various hair types and growth stages in androgenetic alopecia compared to standard PTG and was comparable to biopsy analysis.

Oxidation changes the structure of hair protein filaments, causing them to compact and rearrange.
