This study explored the role of plant-derived monomers in reversing grey hair, finding that compounds like fraxinol and morin may stimulate melanin production and tyrosinase activity, suggesting potential therapeutic benefits, although further evaluation of their safety and efficacy is needed.

This study found that PIXE microanalysis effectively detected and quantified trace element changes in hair shafts, revealing a marked decrease in copper after treatment for green hair syndrome.

This study suggests that in gp91phox-knockout mice, tranexamic acid administration led to brown hair by increasing MGRN1 and collagen XVII levels, while the retention of black hair appears to rely on the gp91phox/ROS/IL-1β/TGF-β pathway.

This study describes a double embedding technique for preparing tangential sections of hair and wool fibers, recommending specific staining methods for quantitative analysis and demonstrating wool fiber cortical fractions.

This study found that a CLSM-based approach could semi-quantitatively assess the transdermal penetration behavior of fluorescent dyes with different lipophilicities, offering a tool for early-stage screening of compound penetration.

In this study, Carthamus caeruleus root juice exhibited in vitro anti-inflammatory effects by stabilizing human erythrocyte membranes and inhibiting albumin denaturation, as well as showing potential inhibition of COX-2 through in silico analysis; however, further research is needed to confirm efficacy and mechanisms.

This study found that a histochemical stain using 4-dimethyl-aminocinnamaldehyde effectively distinguishes between plucked anagen and telogen hairs by causing the root ends of anagen hairs to develop a red color.

This study found that in vitro extracts of Glycyrrhiza glabra root are strong antioxidants, particularly in ethanolic form, and contain secondary metabolites, but only showed mild antibacterial activity.

This study developed a natural hair dye using Coreopsis tinctoria Nutt. extract, finding that it produced yellow to dark brown colors depending on the treatment, with ferrous lactate enhancing dye performance and color stability after washing.

In this study, a new delipidisation method that removes over 97% of key lipids from wool rapidly and without yellowing was reported to improve wool processing and printing quality.

This study found that the new HCC additive enhances the permeation of pigments and active ingredients into hair, suggesting potential use in developing functional cosmetic hair products.

This study found that fluorescent antibody staining effectively differentiated between normal and tumor cells, with observed differences potentially linked to protein composition and developmental factors.

This case report describes a woman who developed green hair due to high copper levels in swimming pool water, exacerbated by hair treatments and inadequate water replacement.

This study found that melanin granules in black human hair are key dyeing regions for oxidative hair coloring, as confirmed by nanoscale mass spectrometry analysis detecting deuterium ions.

In this study, researchers investigated EGCG's spectroscopic properties and its interaction with DPPG lipid, finding that both experimental and theoretical approaches agree on the electronic transitions and reveal an increased absorbance due to molecular interactions.

This study found that the K6/ODC transgenic mouse model is highly sensitive to identifying genotoxic carcinogens, showing 100% concordance with traditional rodent bioassays.

This study reported the development of fluorescent markers using wide band gap metal oxides with rare earth ions for early tumor detection and treatment. Testing in animals showed high efficiency and selectivity, with potential applications in contrast-enhanced MRI, targeted drug delivery, and photodynamic cancer therapy.

This study developed sodium alginate and epigallocatechin gallate cryogels cross-linked with ferric ions, showing that they have strong antibacterial properties and rapid hemostatic abilities, making them promising candidates for wound dressing applications.

This study describes a fast LC/MS/MS method for detecting various synthetic drugs in urine, meeting World Anti-Doping Agency performance limits.

This review examines recent advancements in green and emerging microextraction techniques, such as SPME and DLLME, for more sustainable hormone detection in biological samples, emphasizing environmentally friendly solvents and bioanalytical applications.

This study reports that a 100% herbal hair dye composed primarily of Cymphomandra betacea, Tagetes erecta, and Aloe vera gel provides permanent hair color without causing hair damage, loss, or skin irritation compared to synthetic dyes.

This study developed a novel smart deoxyribozyme-based fluorescent sensor that efficiently detects androgen receptor mRNA with high selectivity and can be adapted to target various nucleic acid sequences.

This study found that in vitro, EGCG may help treat colorectal cancer by targeting iron chelation and the ER stress pathway, leading to apoptosis in cancer cells while sparing normal cells.

This study developed a highly sensitive fluorescent assay for measuring enzyme activity in single hair follicles, allowing the efficient analysis of over 100 samples per day.

Hair dyes penetrate the scalp very minimally, less than 1%.

Krox20 is crucial for hair growth and maintaining skin stem cells.

This study found that oxidative hair dyes altered the color and ultrastructure of Caucasian hair but did not significantly affect the hair's breaking strength.

This study found that inherited color dilution in Rex rabbit hair follicles is associated with DNA methylation changes, contributing to understanding the epigenetic regulation of rabbit pigmentation.

This study investigated the extracellular polysaccharides from the edible green alga Parachlorella sp. BX1.5, finding that they have potential applications in cosmetics and health products due to their stability, antioxidant properties, and effects on hair growth in mice.

This study reports that Cur@CMCTS-Tk hydrogel effectively accelerated wound healing and tissue regeneration in rats by scavenging excess reactive oxygen species and protecting human fibroblasts from oxidative damage.
