In this report, a 19-year-old Japanese man experienced severe and prolonged urticarial reactions following treatment with diphenylcyclopropenone for alopecia universalis, emphasizing the need for caution with potent sensitizers.

This study evaluated the potential toxicity of oral dihydroartemisinin in SD rats, finding that female rats experienced greater toxic effects than males, particularly at higher doses, but these effects were reversible after a 4-week recovery period.

This study found that a laboratory model using nude mice can produce human hair follicles with amino acid compositions resembling both normal and trichothiodystrophy-affected human scalp hair over extended periods.

This study found that deleting transferrin receptor 1 in specific mouse tissues led to varied lethal outcomes, demonstrating its diverse roles beyond iron uptake.

This article reviews anthralin's pharmacology, mode of action, and its use for psoriasis and other dermatoses, but reports no new clinical results.

This study synthesized new heterocyclic steroid derivatives and reported their promising antiproliferative activity against breast and prostate cancer cell lines, highlighting selectivity and impact on signaling pathways even in cells resistant to certain treatments.

This case report describes a 14-year-old female with tufted hair folliculitis, where isotretinoin reduced inflammation and exudation but persistent hair tufting remained, highlighting the challenges in treating this rare condition.

A gene mutation in mice causes increased mast cells and disorganized hair follicles in their skin.

This study found that after topical application in rats, 1,24-dihydroxyvitamin D3 absorbed through both the stratum corneum and hair follicles, with about 30% excreted via the faeces.

This article reviews cultural differences in the incidence of hair-thread tourniquet syndrome and finds it may be less prevalent in Iranian children compared to Europe, possibly due to social and cultural factors.

CTP-543 is generally safe for treating alopecia areata.

An intact skin barrier is crucial to prevent infection in cases of tether-induced tenosynovitis.

This study optimized a screening assay to identify molecules that inhibit or enhance TRPM5 ion channel activity, which may have implications for treating dysfunctions linked to cardiac arrhythmias and diabetes.

This article discusses the preparation of tritium-labeled testosterone metabolites and reports no new experimental findings.

This study found that low ferritin levels are associated with higher telogen ratios in women with diffuse hair loss, suggesting an important role of ferritin in telogen effluvium diagnosis.

This study found that the RapidHIT™ ID system can successfully obtain DNA profiles from single hair roots, particularly those with high nuclei counts.

This study found that in wild-type Arabidopsis plants, root hair growth is suppressed with increased nutrient availability, with RHD6 subfamily genes down-regulated and GTL1 and DF1 genes influencing root hair morphology under these conditions.

This study highlights the significance of the hf pathway for the skin permeation of ionized and hydrophilic high molecular compounds, and the usefulness of hf-plugging in evaluating their skin permeability.

This study found that combining a thulium laser with intra-perifollicular PDRN injections significantly improved hair thickness but not hair counts compared to mesotherapy and PDRN in patients with pattern hair loss.

This review describes advanced drug delivery systems for dithranol aimed at overcoming stability issues and skin irritation seen in conventional formulations, highlighting options like nanoparticles and liposomes for improved psoriasis treatment.

This study found that mild skin injuries in rats, especially those dosed with dihydrotachysterol, lead to mineral deposits in hair follicle tissue within 6-12 hours, as confirmed by chemical and X-ray diffraction analyses.

This study discovered a novel interaction between the vitamin D receptor and LEF1, essential for normal Wnt signaling in keratinocytes, which is crucial for regular hair cycling.

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

This study reported that Tomorrowlabs HIF strengthening factor [HSF] hair restoration technology significantly improved hair thickness, density, shine, and elasticity, while reducing hair loss by an average of 66.8% and enhancing hair growth by up to 32.5% in subjects with androgenic alopecia over nine months.

In this study, researchers found that the deletion of Tet2/3 enzymes in mice led to changes in skin development and hair follicle differentiation, ultimately causing hair loss and altered gene expression.

Direct-to-consumer teledermatology is not effectively reaching underserved populations due to language, technology, and insurance barriers.

This study found that ablation of Tet2/Tet3 genes in skin epithelial cells altered hair shape and length, leading to hair loss, by affecting chromatin accessibility and gene expression related to hair follicle regulation.

This study identified trichohyalin as an early differentiation marker in hair follicles, with potential structural roles related to alpha-helical formations, based on the partial characterization of its cDNA in sheep.

This review discusses the potential conflicts of interest and quality concerns associated with direct-to-consumer teledermatology platforms and reports no new experimental results.
