This study revealed that deficiency in the enzyme FA2H in mice affected sebaceous gland function, altered sebum composition, and caused cycling alopecia, highlighting FA2H's role in hair follicle homeostasis.

This study found that bioconjugating 16-methylheptadecanoic acid to damaged human hair can mimic the protective function of the original 18-methyleicosanoic acid, effectively restoring both the hair's external structural integrity and its internal moisture balance.

In this case study, researchers detailed two Saudi cases of the ultra-rare Trichohepatoneurodevelopmental syndrome, identifying pathogenic variants in the CCDC47 gene and reinforcing a strong gene-disease association, which helps clarify the disorder's clinical features and genetic mutations.

This study found that a dopamine-methacrylated hyaluronic acid hydrogel enhances the efficacy of adipose-derived stem cells in promoting skin regeneration, potentially involving the Notch signaling pathway.

In this case study, electron microscopy revealed that harlequin ichthyosis involves giant mitochondria in keratinocytes and abnormal lamellar granule development, which may contribute to pathogenesis through altered lipid metabolism.

This study identified the c.1204G to A (p.E402K) mutation in the hHB6 gene as a cause of monilethrix in a Chinese family, highlighting the gene's role in the condition.

In this study, researchers developed a dexpanthenol-infused nanotechnological platform within hyaluronic acid hydrogels that promoted wound healing in mice by providing a protective barrier and significantly enhancing skin regeneration, including increased fibroblast activity and tissue remodeling.

This study introduced a novel framework that significantly improves the accuracy of alopecia areata lesion segmentation in semi-supervised scenarios, outperforming existing methods and aiding in the disease's diagnosis, treatment, and staging, which can impact quality of life and mental well-being.

The hydrogel helps heal seawater-immersed wounds by reducing infection and inflammation.

Scientists made glow-in-the-dark dots from human hair that can detect iron, prevent counterfeiting, and reveal fingerprints.

This study found that mutations in exon 3 of the hr gene are strongly associated with congenital hypotrichosis in Valle del Belice sheep, suggesting a potential genetic link to the disorder.

This study identified and characterized a murine type II hair keratin, demonstrating its presence in specific cells of hair and tongue tissues.

This review examines the benefits of topical hyaluronic acid in cosmetic applications, noting its ability to penetrate the skin in low-molecular-weight forms and highlighting safety supported by clinical trials.

This study found that AHCC significantly reduced alopecia caused by Ara-C in neonatal rats and improved liver function affected by 6-MP and MTX in mice.

This study found that hyaluronic acid increased the size of hair follicle germ-like aggregates and the number of proliferative cells but did not maintain specific markers during the process.

This review discusses the need to update the Rotterdam diagnostic criteria for polycystic ovarian syndrome, highlighting issues with current definitions and proposing new markers like serum anti-Müllerian hormone, but reports no new clinical results.

The authors concluded that establishing and standardizing methods for data collection are crucial to improving PCOS diagnosis and research due to challenges observed in data harmonization across diverse international cohorts.

The research observed that among Ecuadorian Andean women with polycystic ovary syndrome, classical phenotypes A and B were more prevalent and associated with higher risks of insulin resistance and metabolic disorders compared to phenotypes C and D.

This case report describes a 16-year-old girl with HAIR-AN syndrome requiring a multidisciplinary approach, including lifestyle changes and hormonal treatments, to manage symptoms and prevent systemic effects.

This study identified a monoclonal antibody, HKN-2, that recognizes specific cells in human skin and may indicate a common antigenic determinant between hair and other skin epithelial tissues.

This study found that the pH-sensitive hydrogel HECHA13, containing isoliquiritigenin, effectively inhibited the growth of Propionibacterium acnes and showed promise for transdermal delivery in acne treatment.

This study found a novel R430Q gene mutation in hHb6, which may be linked to the hereditary hair disorder monilethrix in the examined family.

In this study, the researchers developed a hydrogel mimicking the fetal environment that significantly accelerated wound healing and hair follicle regeneration in vivo, with over 94% wound closure in 14 days, surpassing hydrogels lacking certain additives.

This study suggests that Keratin 6hf may be a potential marker of oral squamous cell carcinoma and could play a role in its progression, though further research is needed to understand its function.

A new mutation in the HR gene causes hair loss in a specific family.

This case report describes the first known association of hypertrichosis lanuginosa acquisita with autoimmune hepatitis, expanding the list of conditions linked to this rare disorder.

This study reports that gastrointestinal problems, such as intractable diarrhea and enterocolitis, can dominate the clinical course of patients with Hoyeraal-Hreidarsson syndrome and may occur before hematological and immunological symptoms.

This study found that low-molecular-weight hyaluronate significantly improved the mechanical strength and elastic modulus of overbleached hair by enhancing hydrogen bond networks within keratin.
