This study found distinct skin surface changes, including faint mosaic melanoderma and atypical scaliness, on long-standing sun-exposed balding scalps that may be associated with actinic field carcinogenesis.

This study reports that some human cell surface HLA-I molecules (including HLA-B27) can appear without their usual peptide component, potentially altering immune interactions, influencing arthritis development in specific mice models, and exhibiting upregulation in certain cancer cells.

This study found that in naturally curved human scalp hairs, distinct arrangements of cell types on either side of the hair fiber contribute to its curvature.

This review discusses new research on the role of retinoids in skin and hair health and reports no clinical results.

This narrative review found that post-COVID-19 hair loss, particularly telogen effluvium, poses a significant mental and social burden, with minoxidil potentially aiding recovery, although more clinical research is needed to confirm its effectiveness.

This study found that overexpression of ovine β-catenin in transgenic mice increased hair follicle density by promoting the transition from catagen to anagen.

In this study, researchers identified key lncRNAs and target genes potentially involved in the transformation of the hair follicle cycle, which could advance understanding of lncRNAs' roles in hair follicle development.

This review explored recent research on the immune mechanisms and potential therapeutic targets for alopecia areata, highlighting the roles of immune-related cells, autocrine and paracrine signaling, as well as factors like adipose-derived stem cells and gut microbiota in disease pathogenesis.

This review discusses the role of the MC1R gene in human pigmentation and its genetic variants, reporting no new results; the authors highlight its forensic applications for phenotypic prediction.

This article discusses photobiomodulation as a potential adjunct to hair follicle organoid culture for androgenic alopecia, reporting no new results and suggesting further study is needed.

This review summarizes existing knowledge on diffuse and patterned alopecia, emphasizing recent advancements in treatment beyond FDA-approved options, but it reports no new clinical findings.

In this study, researchers observed significant differences in microbial composition between UV-induced fluorescent and non-fluorescent scalp areas in patients with androgenetic alopecia, noting a higher abundance of Cutibacterium in the fluorescent regions.

This study suggests that UVA-responsive nanocapsules may provide an effective method for skin antisepsis by releasing ethanol and reducing microorganisms within hair follicles on ex vivo porcine ear skin.

This study investigated the physicochemical properties of polystyrene-b-poly(acrylic acid) nanovesicles coated with modified chitosans, finding that they can effectively control surface charge and potentially serve as drug delivery carriers with a 50.7% encapsulation efficiency for minoxidil.

This study found that genipin-based pigments, accelerated by riboflavin and blue-light photocatalysis, achieved commercial-level hair dye results with enhanced gloss and excellent color retention while reducing cuticle disruption, offering a potentially safer and faster alternative to traditional hair coloration methods.

This study reported that fermented grapeseed oil may enhance hair permeability and improve strength and color retention in chemically treated hair compared to regular grapeseed or silicone oils.

In this study, researchers developed an environmentally friendly hair coating from casein proteins and tannic acid, enhancing the tensile strength of virgin Asian hair by approximately 21% compared to untreated hair, while maintaining elasticity.

This study suggests that hemoglobin α expression in the epidermis is induced by oxidative stress and may function as an antioxidant, contributing to skin barrier function.

This study on Sdr16c5/Sdr16c6-null mice found that inactivating these genes significantly increased Meibomian gland secretions and altered lipid profiles but had a subtle impact on sebogenesis, suggesting the genes control a bifurcation point in meibogenesis pathways.

The study concluded that fatty acid transport protein 4 in epidermal keratinocytes is crucial for maintaining normal skin structure, as its deficiency led to hyperkeratosis and epidermal barrier disruption in mice.

This study found that the acyl-CoA binding protein is essential for the production of very long chain free fatty acids in the stratum corneum and maintaining normal epidermal barrier function in mice.

This study found no evidence that HDGF expression transforms melanocytes into tumors in a mouse model, although it may play a role in cell differentiation and tumor progression.

This review synthesizes research on solar radiation's multifaceted effects on skin and recent advancements in sunscreen technology, including formulation, testing methods, and the use of AI, to inform future sun protection product development.

This study found that mitochondrial dysfunction and higher oxidative stress in balding dermal papilla cells may contribute to androgenetic alopecia, with antioxidants potentially improving metabolite uptake.

The researchers reported that PPARβ/δ may influence the yak hair follicle cycle by modulating lipid metabolism in dermal papilla cells, with varying expression during different hair growth phases, affecting both lipid content and cell proliferation.

This study identified key proteins, FKBP10 and FBN2, that promote the growth cycle of secondary hair follicles in cashmere goats, with higher expression in the anagen phase, offering insights into mechanisms potentially enhancing cashmere yield and quality.

This review of low-level laser therapy for patterned hair loss found that red-spectrum light may be effective for hair growth, but larger case-controlled studies are needed to further support this conclusion.

In this study, researchers developed a method to efficiently derive contractile smooth muscle cells from human hair follicle stem cells using TGF-β1 and PDGF-BB, which may advance vascular tissue engineering.
