In this study, researchers found that the synthetic stress hormone dexamethasone caused opposite effects on hair growth-related proteins, reducing SFRP2 and increasing SFRP3, which respectively stimulate and inhibit hair follicle cell proliferation in human dermal papilla cells.

This study found that dexpanthenol treatment reduced inflammation, oxidative stress, and apoptosis in rats, providing a protective effect against lipopolysaccharide-induced cardiac and endothelial damage.

This study reported that the prevalence of atopic dermatitis in cats was higher than previously suggested, with severe nonseasonal pruritus most common, and certain breeds were predisposed.

This research observed that, in domestic cats like Maine Coon and Rex breeds, a "piebald" coat color pattern is likely influenced by the Silver locus, although the specific mutations involved are yet to be published.

This study found that LY320236 is a competitive inhibitor of type I and a non-competitive inhibitor of type II steroid 5alpha-reductase, indicating its potential as a dual inhibitor with differing modes of activity.

This abstract contains navigation and subscription information for JAMA Dermatology and reports no new clinical findings.

This article reviews the potential link between botulinum toxin treatment and alopecia but provides no new research findings.

In this study using genetic mouse models, researchers discovered that senescent melanocytes in nevi secrete osteopontin, which activates hair stem cells, enhancing hair growth; this process is mirrored in human hairy nevi, suggesting a potential therapeutic target for regenerative disorders.

This article describes international efforts by dermatologists to launch and harmonize registries focused on COVID-19's dermatologic impacts, aiming for better global collaboration and data sharing.

This study found that hair proteome profiling and genetically variant peptide identification in hairs remained effective after an explosive blast, indicating potential for forensic human identification despite damage.

This study developed a quantitative measure for scoring hair surface damage from SEM images and found it accurately classified hair damage caused by explosive blasts, similar to an existing classification system.

In a comparative genomic study, researchers observed significant genetic differences among the three chemical races of the alga Botryococcus braunii, leading them to propose reclassifying these races as distinct species based on their unique genomic characteristics.

This article reviews global insights on how COVID-19 has transformed the practice of dermatology, but it reports no new clinical results.

In this study, researchers identified that three homologous genes—ZmSPL10, ZmSPL14, and ZmSPL26—are crucial for the development of stigmatic papilla in maize, with triple knockout mutants lacking these genes showing almost no stigmatic papilla and significantly reduced kernel setting.

This study found that hydrophilic carbon dots (Lys-CA-CDs) induced bovine serum albumin to form more wormlike fibrils, while inhibiting hen egg white lysozyme from forming hair-like fibrils.

In this open-label study, participants reported that the LustrivaTM BH-002 two-step system improved various aspects of hair, skin, and nail health and appearance after three months of use.

This article discusses the high toxicity and potential use of thallium as a poison, highlighted by two cases of intentional thallium poisoning.

This study found that a genetic variant in the EDAR gene leads to typical East Asian hair characteristics by increasing signaling output, as shown in transgenic mice experiments.

This article discusses the disputed role of scalp micro-organisms in dandruff and notes that effective anti-dandruff treatments often have good antimicrobial activity, but it reports no new clinical results.

In this study, health state utility values revealed a significant impact on quality of life for patients with alopecia areata, particularly those with more extensive hair loss.

This study indicates that the EQ-5D-5L may not effectively capture the burden of alopecia areata on patients' health-related quality of life, and suggests that alternative measures might better assess treatment benefits related to hair regrowth.

This study examines how thirteenth-century French authors used hair and animal traits to interrogate social identities and gender roles, reflecting broader religious, political, and cultural discourses of the time.

Estetrol (E4) can help hair grow longer by extending its growth phase.

This study observed that patients with AA showed a high willingness to trade off lifespan for better disease-specific quality of life, indicating a significant disease burden.

This study found that estetrol (E4) significantly prolonged the anagen phase and increased hair matrix keratinocyte proliferation in cultured human hair follicles, suggesting its potential as a treatment for female pattern hair loss.

In this study, estetrol (E4) treatment was associated with increased hair growth in ex vivo human hair follicles, suggesting its potential as a treatment for hair loss disorders.

Human hair's structure makes it tough and resistant to breaking.

This study reports that while primary treatment for uveal melanoma has a very high success rate, treating distant metastases, particularly in the liver, remains challenging. Tebentafusp, dependent on HLA-A expression, is the first drug to extend patient survival.
