This study suggests that decorin may help maintain hair follicle stem cells and its reduced expression could contribute to age-related hair loss.

This case series describes three siblings with hereditary vitamin D-resistant rickets, highlighting variations in their clinical presentations.

This study found that videodermoscopy enhances diagnostic accuracy for scalp and hair disorders beyond simple clinical inspection and reveals novel disease features that could improve clinical understanding.

This study found that Sonic Hedgehog secreted by hair follicle transit-amplifying cells is essential for dermal adipogenesis and hair follicle growth by acting on adipocyte precursors.

This review discusses the integration of ultrasound in dermatology for improved lesion visualization and diagnosis, highlighting recent technological advancements like handheld devices and high-frequency probes, and reports no clinical results.

This study found that 70-MHz ultrasound can detect early signs of hidradenitis suppurativa linked to severity, including hair follicle abnormalities and keratin fragmentation, aiding in diagnosis and management.

This case report describes a rare instance of Vogt-Koyanagi-Harada disease in a 21-year-old Asian woman, highlighting unusual oral manifestations such as tooth discoloration and misalignment, which expand the known clinical spectrum of the disorder.

This study found that ectodermal precursor cells derived from human induced pluripotent stem cells may enhance hair follicle morphogenesis through improved epithelial-mesenchymal interactions when cocultured with dermal cells.

This case report describes a 40-year-old woman with Birt-Hogg-Dubé syndrome diagnosed with multiple chromophobe renal cell carcinomas, highlighting the importance of recognizing associated dermatologic lesions for early intervention.

This study showed that exosomes from hyaluronic acid-primed induced mesenchymal stem cells promote hair growth by enhancing proliferation and migration of hair follicle dermal papilla cells and modulating key growth factors and signaling pathways, potentially counteracting the effects of DHT-induced hair loss.

This study found that applying HHORSC exosomes may enhance the hair inductivity of dermal papilla cells, potentially improving treatments for hair loss.

A specific gene mutation causes sparse, brittle hair in a family.

This study found that hidradenitis suppurativa is associated with increased serum levels of hypoxia-inducible factor-1α, suggesting its role in the disease's pathogenesis and as a treatment target.

This study found that the 15-PGDH inhibitor DPP improved endothelial function in hair-related cells exposed to DHT by reducing oxidative stress and enhancing angiogenic capacity.

This study mapped a spontaneous mouse hair mutation, "hague," to keratin genes on chromosome 15 but found no gene mutations in hague mice.

This study found that dermal white adipose tissue surrounding human hair follicles enhances proliferation, pigmentation, and hair shaft elongation in an ex vivo setting.

Intense pulsed light with radiofrequency showed mixed results in improving quality of life for hidradenitis suppurativa patients, with no clinical improvements.

This review discusses recent insights into Birt–Hogg–Dube syndrome, including the functions of the FLCN gene and clinical recommendations for screening and treatment, but it reports no new experimental results.

This study suggests that the C-terminal of AHF is crucial for its binding to keratin bundles and modulating the keratin meshwork in hair follicles.

This study found that the heat shock cognate protein Hsc70 was differentially expressed by dihydrotestosterone treatment in SV40-transformed dermal papilla cells, suggesting its involvement in androgen action on these cells.

In this study, patients with specific skin and scalp conditions, including eczematous lesions, showed significant improvement after two weeks of oral tofacitinib treatment, as evidenced by changes in the trunk lesions.

This study found that Shh and Dhh overexpression in mouse basal cells led to similar epidermal and limb phenotypes, suggesting Dhh functions similarly to Shh in skin, unlike Ihh.

This study developed a biomimetic 3-D co-culture system that enhances the hair-inductive properties of human dermal papilla cell aggregates, potentially improving hair follicle tissue engineering.

This study suggests using a handheld dermatoscope may allow for simple and efficient differentiation of eruptive vellus hair cysts by detecting vellus hair shafts, as demonstrated in a familial case involving five women.

This study characterized two siblings with hereditary vitamin D resistant rickets and a mutation in the vitamin D receptor, finding no immune-related disorders despite a defective T cell response to vitamin D.

This review provides an overview of the hairless gene in mice and humans, discussing its structure, expression, and implications for understanding skin physiology and human disorders related to gene disruption, but it reports no new empirical findings.

In this study, diode laser treatment showed greater efficacy in reducing facial hair and increasing satisfaction among hirsutism patients with normal levels of DHEAS and DHT, compared to those with deranged levels, although some benefits were observed across both groups.

This study suggests that lithocholic acid may enhance hair regeneration in alopecia by activating vitamin D receptors in human dermal papilla cells.

This study found that human dermal stem/progenitor cells demonstrated greater proliferation and differentiation potential than hair follicle dermal papilla cells, which showed increased expression of hair regeneration markers.
