This study found that disrupting the PRL gene in mice alters the timing of hair cycling events, causing earlier molts and changes in hair characteristics, particularly affecting female mice more significantly.

This study demonstrated that using a mass spectrometry imaging technique, researchers were able to visualize the incorporation of argan, avocado, and coconut oils into hair fibers, suggesting their potential in cosmetic and alopecia treatments by confirming oil absorption and fiber modification.

This study introduced a novel in vitro assay for tracking melanosome transfer between melanocytes and keratinocytes, facilitating the quantification of melanin transfer and supporting the role of filopodia as a conduit.

This study identified specific miRNAs and mRNAs involved in the development of secondary hair follicles in cashmere goats, particularly noting a targeted relationship between chi-miR-30e-5p and DLL4.

In this study, curcumin-loaded nanoparticles with a size of 400 nm showed optimal accumulation in human hair follicles after seven days, although mouse models differed significantly in penetration and retention, indicating limitations in their suitability for follicular drug delivery studies.

This chapter reviews hair anatomy, hair shaft structure, and various cosmetic treatments that can alter or damage hair, but it presents no new research findings.

In this study, researchers found that neonate hairs have a distinct microstructure with no medulla and smaller hair follicles compared to adult hairs.

This study demonstrated that modified montmorillonites combined with bacterial cellulose enhanced antimicrobial, wound healing, and tissue regenerative activities in a burn mice model, suggesting potential as an artificial skin substitute for burn patients.

This study found significant structural and compositional differences in hair affected by alopecia areata compared to healthy hair, using a range of physico-chemical investigation methods.

Hair treatments like bleaching increase friction by exposing tiny pores on the hair surface.

This study found that chemical treatments like perming, dyeing, and bleaching significantly alter amino acids and lipids in human hair, which may impact hair strength and quality.

This review discusses in vitro methods for evaluating the effects of hair care products on hair fibers, reporting no new results; the authors emphasize the importance of selecting appropriate and accurate equipment for testing.

This study found that scanning electron microscopy can identify four specific hair morphology patterns in alopecia areata patients, offering a less invasive diagnostic option compared to punch biopsy.

This study identified a novel mutation, R430Q in the KRT86 gene, in a Han family with monilethrix, which may contribute to the disease's pathogenic mechanism.

In this study, an infection model using rabbits was developed for dermatophytosis by inoculating macroconidia of Microsporum species, showing that direct intradermal application effectively progressed to the skin invasion phase and highlighted the correlation between severity of symptoms and duration post-inoculation.

This study presented a case of tinea capitis in a 4-year-old without typical symptoms and traced the infection to Microsporum canis carried by domestic cats, highlighting the need for accurate diagnosis and appropriate treatment, especially in households with pets.

This paper discusses advancements in forensic hair analysis, emphasizing a novel DART–HRMS method that improves the accuracy and efficiency of detecting drug use timelines.

This study found that using henna dye positively affected hair cuticula pattern and diameters compared to undyed hair, though the degree of change may vary based on hair phenotype and condition prior to treatment.

Innovative methods are reducing animal testing and improving biomedical research.

In this study, Alox15 knockout mice exhibited disrupted skin integrity and increased inflammation, suggesting that Alox15-mediated resolvin D2 production is crucial for maintaining skin homeostasis by suppressing inflammation.

This study identified new geometric and mechanical parameters for curly and kinky/coily hair, which may inform more effective personal care products tailored to these hair types.

This study used quantitative methods to identify new geometric and mechanical parameters of curly and kinky/coily hair, aiming to improve classification and develop better personal care products for these hair types.

This study identified a set of wound-induced genes in planarians that play a role in regeneration initiation, with some genes specifically activating within regenerative cells called neoblasts.

This study found no significant genetic association between the 5α-reductase enzyme genes and male pattern baldness, suggesting a polygenic etiology rather than simple inheritance.

This study found that the methanol extract of Eclipta alba showed dose-dependent hair growth promoting activity in pigmented C57/BL6 mice by influencing the transition from the telogen to anagen phase.

This study demonstrates that inhibiting SFRP1 with the antagonist WAY-316606 enhances hair growth in human scalp hair follicles ex vivo by facilitating Wnt signalling.

This study explored the expression and potential functions of long non-coding RNAs in the skin pigmentation of Koi carp, revealing their involvement in pigmentation and differentiation mechanisms.

This study established a new in vitro culture system that supports the growth and dynamic self-organization of hair follicle stem cells and their progeny, promoting a stable population equilibrium.

This study found that a new topical nitric oxide gel significantly accelerated burn wound healing in mice by enhancing re-epithelialization, hair follicle regeneration, collagen deposition, and angiogenesis compared to controls.

This study used proteomics to identify various proteins in human hair, which may help develop novel biomarkers for hair health, disease, and aging.
