This study demonstrates that polarized second harmonic generation imaging effectively monitors wool fiber stretching, revealing significant structural changes in keratin alignment that improve textile performance.

This review discusses the hormonal impact on hair growth and the relationship between endocrine disorders and hair changes, reporting no new clinical results.

In this study, researchers found that taking Saw palmetto and Pygeum africana supplements for five days altered the urinary steroid profile in a way that may interfere with the steroidal module of the Athlete Biological Passport.

This study found that nonscarring alopecia in patients with systemic lupus erythematosus may indicate higher disease activity, as evidenced by specific histological and immunofluorescence changes.

This study suggests that the curly hair phenotype in Mangalitza pigs may involve complex gene interactions related to calcium signaling and lipid metabolism, rather than changes in TRPM2 or CYP4F3 expression.

This research identified two genetic variants that influence the white-spotted coat patterns in Holstein-Friesian cattle, involving regulatory changes in the MITF and KIT genes, confirmed through mouse models, along with possible effects on coat patterns in other cattle breeds.

In this study, researchers differentiated human induced pluripotent stem cells into dermal papilla-like cells and observed gene expression dynamics during five stages of dermal differentiation, demonstrating the potential of these cells to interact with epidermal cells in functional assays.

This case report describes a 41-year-old man with preauricular and postauricular plaques unresponsive to topical treatments, with lab results indicating low-titer antibodies for Sjögren syndrome A and B.

This review discusses the role of proteomics in understanding skin diseases such as cancers and psoriasis, with findings suggesting cell death and metabolism as major areas of focus, but reports no new experimental results.

In this study, trypsin digestion was found to be a faster and more efficient method than the explant technique for extracting bulge-derived keratinocytes from adult scalp biopsies.

This review discusses the potential role of vascular endothelial cells as signaling niches influencing epithelial stem cell states in the skin, emphasizing the need for further exploration in this area.

COVID-19 might cause gray hair to regain color.

This letter argues that cicatricial pattern hair loss likely represents end-stage androgenetic alopecia and not a variant of lichen planopilaris, as previously suggested.

This report details a case of a 58-year-old male diagnosed with erosive pustular dermatosis of the scalp, which improved following 3-5 weeks of treatment with topical clobetasol proprionate.

This article reports on a partial regrowth of scalp hair in a patient treated with extracorporeal photochemotherapy and interferon α 2a, but provides no new clinical outcomes.

This study reviews drug-induced hair changes, noting that hair loss often reverses after stopping the drug, but permanent alopecia cases post-chemotherapy are rising.

This case report describes a dog diagnosed with discoid lupus erythematosus, presenting unusually with perianal rather than facial lesions, which resolved after corticosteroid treatment.

This review explores the significant impacts of hormonal changes within normal physiological ranges and suggests examining low-dose effects from chemicals disrupting hormonal activity; it presents no new clinical results.

This study identified three symptom trajectory groups in individuals with PMDD, highlighting variations in symptom severity and duration across the luteal and follicular phases.

This review discusses the adnexotropic presentations of interface dermatitides and highlights the importance of recognizing adnexal involvement to aid in accurate diagnosis and avoid misinterpretation.

This study observed that rat vibrissa hair follicles cultured in vitro showed morphological changes suggesting cyclical activity but remained blocked in the pro-anagen stage.

This review describes nail changes linked to various non-infectious skin diseases, highlighting how these alterations can help diagnose and manage conditions like psoriasis and lupus by noting specific and overlapping nail characteristics.

This study found that terpene compound concentrations in coniferous tree leaves were generally highest in spring and summer, suggesting these seasons are most effective for extracting essential oils.

In this study, transgender adolescents treated with testosterone for a median of 12 months experienced effective virilization, including voice deepening and increased hair growth, but also showed decreased HDL cholesterol and BMD z-scores, and increased hematocrit, with no short-term safety issues reported.

This study demonstrates that spatially resolved IR and Raman imaging can effectively reveal the molecular structure and composition of untreated human hair, providing insights into its chemistry and structural integrity.

This study investigated the tensile response and morphological changes of different ethnic hair types using AFM, showing variations between virgin, chemically damaged, and conditioner-treated Caucasian hair under different conditions.

This study found that doxorubicin induces hair follicle apoptosis through TRAIL receptor signaling, providing insights for managing chemotherapy-induced hair loss.

This review discusses the classification and regulation challenges of anti-ageing cosmetics in Europe and reports no new findings; it calls for increased transparency to help consumers make informed choices.

In this study, researchers found that overweight and obese women with polycystic ovary syndrome showed adverse changes in glucose metabolism over time, highlighting the importance of early intervention to prevent cardiometabolic diseases.

Hair increases in size when it absorbs water, and treatments like bleaching affect how much water it can take in.
