This study observed that distinct subsets of Hoxd genes in murine vibrissae and chicken feather primordia are regulated by different lineage-specific enhancers, indicating evolutionary changes in chromatin topology contribute to transcriptional robustness.

This study used Raman spectroscopy and wide-angle X-ray scattering to observe two main α-helix to β-sheet transitions in hair keratin under varying humidity levels, finding that water impacts when these structural changes occur, involving a disordered state.

Hair graying may help prevent cancer by protecting stem cells.

In this study, researchers developed a natural herbal shampoo using extracts from plants like amla and aloe vera, demonstrating effective hair and scalp cleansing, good foaming capacity, and eco-friendliness, aligning with consumer demand for sustainable personal care products.

In this study, researchers developed a natural herbal shampoo using ingredients like amla and aloe vera, finding it effectively cleans hair and scalp, promotes hair growth, and meets eco-friendly personal care product demands, without synthetic additives.

This study revealed that during avian skin development, complex tissue architecture results from specific cellular flows and mechanical processes that guide feather bud protrusion and elongation, with distinct differences noted in scale development, where rigidity restricts such transformations.

This literature review discusses exosomes' potential as biomarkers and therapeutics for skin issues, hair loss, and wound healing, but notes that their full functions and standardized applications remain inadequately understood.

This review highlights recent advancements in FUE hair transplantation techniques and technologies, noting significant improvements in reducing follicle damage and increasing procedure speed, while emphasizing the need for surgeons to choose suitable devices for each patient's specific needs.

This research identified genetic sequences that evolved at different rates in hairless versus hairy mammals, suggesting specific genetic changes contributed to the convergent evolution of hairlessness across various mammalian species.

This study found that humans have a much higher eccrine gland density than chimpanzees and macaques, suggesting a unique evolutionary path for human skin features.

This article discusses the structure and protective function of pangolin scales, emphasizing their composition of α-keratins and β-keratins, and highlights evolutionary keratin diversification in tetrapods; it reports no new empirical findings.

This case report describes a 17-month-old girl who experienced sudden hair whitening during septic shock, suggesting systemic stress may trigger canities subita in young children and highlighting the need to distinguish it from congenital pigment dilution syndromes.

In this case study, a 17-month-old girl experienced sudden hair depigmentation during septic shock hospitalization, suggesting systemic stress as a potential trigger for pediatric canities subita associated with diffuse alopecia areata.

This review explains methods for studying chromatin variation at the single-cell level using scATAC-seq and discusses integrating these measures with other omics platforms but reports no new results.

This review explores recent advances in inflammation resolution and considers how macrophage reprogramming might help address severe COVID-19 outcomes, particularly those involving cytokine storms, but it reports no new experimental results.

Combining paroxetine and triamcinolone effectively treats both alopecia areata and depression.

This review highlights how disruptions in the host microbiome can worsen inflammation and infection-related pathology, while it remains unclear exactly how the microbiome helps resolve such inflammation, potentially impacting future treatments for infection-induced inflammatory diseases.

Ancestry affects skin healing, with non-Hispanic Black patients showing more healing-related fibroblasts than White patients.

This study suggests that observing the acute telogen effluvium triad—frontal fringe, temporal recess, and occipital fringe—can aid in diagnosing telogen effluvium during resolution phases, despite challenges like negative pull tests.

This study used single-cell transcriptomic analysis to identify a specific cell population in acne patients' non-lesional skin, providing evidence for the comedone switch hypothesis by suggesting a shift towards infundibular differentiation at the expense of sebaceous gland maintenance.

This review highlights the complex role of leukocyte migration in both driving inflammation and facilitating its resolution, suggesting that targeted modulation of this process could improve therapeutic strategies for inflammatory diseases.

Baricitinib can help improve hair loss and skin color issues in people with Down syndrome.
