This study created new methods to test how well hair care products clean and protect hair from pollution, finding a wide range of effectiveness among different formulas in removing pollutants and preventing their deposit on hair fibers.

This study characterized keratin-based biomaterials that self-assemble into hydrogels, demonstrating their potential to achieve hemostasis in a lethal liver injury model through specific biomaterial-receptor interactions.

Gene expression in wool follicles changes with growth cycles, offering insights into wool and human hair growth.

In this study, researchers found that hair follicle orientation in Fz6 −/− mice is disrupted and that hair may reorient itself over time through a self-organized process.

This study reviews the biology and cosmetic treatment of hair, emphasizing future advancements in safer, more effective procedures to meet consumer needs for hair care.

This study found that mice lacking alkaline ceramidase 1 with elevated skin ceramide levels showed disrupted skin homeostasis, including altered hair follicle structures, increased water loss, and a hypermetabolism phenotype.

This study found that lncRNA H19 may regulate CTGF expression in KGN cells by acting as a "sponge" for miR-19b, potentially influencing polycystic ovary syndrome development.

This study found that recombinant human FGF9 expressed in Arabidopsis thaliana oil bodies significantly promoted the proliferation of NIH/3T3 cells.

This article reviews the pathogenesis and treatment approaches for premature graying of hair, noting the unsatisfactory options currently available, and reports no new clinical findings.

This study found that Keratin 26 is expressed differently in hair follicle phases, particularly during catagen and telogen, influencing cashmere growth and interacting antagonistically with the BMP signaling pathway.

This study found that GDNF promotes hair formation and skin wound repair by enhancing the self-renewal and differentiation of bulge stem cells in mice.

This study found that sphinganine may improve scalp health, hair quality, and reduce hair loss in males, potentially due to increased antimicrobial peptide levels and inhibition of 5-α-reductase.

This review reports that various bioactive compounds in Aloe vera demonstrate significant anti-inflammatory, antioxidant, antibacterial, and immunomodulatory effects, supporting its validated use in treating metabolic disorders, gastrointestinal recovery, dermatological conditions, and wound healing due to its nutritional and therapeutic properties.

This study explored the complex developmental processes of human hair, emphasizing the intricate interactions required for hair follicle morphogenesis and its implications for drug incorporation and concentration interpretation, particularly in early childhood.

This case report describes a severe Sarcoptes scabiei infestation in a stray FIV-positive cat, which typically is a non-permissive host for the mite, leading to considerable clinical recovery after treatment.

Mammalian hair scales change from smooth to wavy due to friction.

This review synthesizes current knowledge on choriogenesis, the final stage of oogenesis in insects, by exploring the role of follicle cells, regulatory mechanisms of gene expression, and the biochemical makeup of the eggshell, while also highlighting structural diversity and adaptations across insect species.

This study reported that discarded squid ink was used to develop a high-performance, environmentally friendly hair dye that offers a stable deep black color, UV protection, and preserves hair structure, while showing excellent biosafety in lab tests.

In this comprehensive review, researchers reported that macromolecules like type I collagen, keratin, and ceramides enhance hair health by improving follicular function and increasing hair density, strength, shine, and resilience, as shown in various in vitro, animal, and human studies.

This study found that different polypeptides, including KP peptide and hydrolyzed keratin, can improve the mechanical properties of damaged hair under varying conditions, with reduction environments and cysteine content influencing their effectiveness.

This study observed that repeated low-depth microneedling in patients with androgenetic alopecia led to initial hair improvement but subsequently caused hair-shaft fragility and breakage, suggesting iatrogenic damage.

In this study, researchers linked SARS-CoV-2 infection to telogen effluvium in some COVID-19 patients by observing the accumulation of viral proteins in hair follicle cells, which may trigger stress responses and cell death, suggesting hair follicles as a potential target in COVID-19.

In this study, researchers found that the lipid composition in hair significantly affects water diffusion and may explain differences in dyeing and cosmetic treatment responses between Asian and European hair, with CP2 fibers having more lipids than CP3 fibers.

This article highlights that trichorrhexis nodosa, a common type of hair breakage, is influenced by factors like heat styling and chemical treatments, with potential FDA action on formaldehyde usage in hair products potentially altering its treatment approach.

This review highlights jojoba oil's unique composition and its growing therapeutic applications, noting its antioxidant, anti-acne, antidiabetic, and antibacterial properties, as well as its use in various pharmaceutical formulations.

This study examined the age-related changes in the dermal structure of goat skin, providing baseline data on its histomorphology, histochemistry, and histoenzymology.

This article reviews the case of a patient diagnosed with basal cell nevus syndrome and reports no new research findings.
