This study found that acetyl zingerone methyl ether (MAZ) in hair dyes and haircare products may reduce oxidative damage, improve hair condition, and enhance the longevity and quality of dyed hair color.

This study explored chitosan-based dissolving microneedle arrays loaded with Agave tequilana root extract, finding that extract concentration influenced microneedle geometry and bioactivity, maintaining antioxidant and enzyme inhibitory effects while reducing collagenase inhibition, particularly in the 0.25% formulation.

This study found that tenuazonic acid from Alternaria alternata can cause significant damage to vital organs in mice at low doses and highlights the need for regulatory measures to manage its risk in agricultural products.

Caffeine and siloxanetriol alginate caffeine in emulsion form can reduce fatty cell size and number, potentially treating cellulite effectively.

This abstract provides no research results, focusing instead on navigation and subscription details for JAMA Dermatology content access.

Specific cross-linkages help make hair proteins stable and strong.

This study developed granular hydrogels with reversible interparticle cross-linking, finding they offer high mechanical stability and enhance cell recruitment, making them promising for injectable and 3D printable scaffolds in tissue engineering and therapeutic delivery.

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.

In this study, researchers developed a novel TA-encapsulated microneedle applicator that successfully promoted hair growth and reduced inflammation in a C3H/HeJ mouse model of alopecia areata, potentially offering an improved alternative to existing treatments.

In a murine model of androgenetic alopecia, this study found that the newly designed IGF-1 biomimetic peptide Ac-GFFY-IGF led to faster and superior hair regrowth compared to minoxidil, suggesting potential for improved human therapies.

In this study, the novel thiol-Michael click perming molecule, MA2-CySS, achieved repeatable perming with reduced oxidative damage, preserving hair keratin's structure while maintaining efficiency comparable to traditional oxidative methods.

In this study, researchers developed a method using stencils to create controlled stiffness gradients in alginate hydrogels, revealing that stiffer regions within the gels promote deeper invasion by breast cancer cells, facilitating the study of mechanosensitive cellular behaviors.

This study found that administering botulinum toxin A via Flex-PADs to mouse footpads inhibited sweating similarly to traditional injections, suggesting a promising patient-friendly delivery method for hyperhidrosis treatment.

This study from Los Angeles supports the idea that using permanent hair dye may increase bladder cancer risk in US women, especially those with a slow NAT2 acetylation phenotype.

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 study developed a new analytical method to identify a wide range of endocrine disrupting compounds in full-term amniotic fluid, revealing diverse substances with potential endocrine activity.

This study discusses the effects of incorporating various amino acids in hair care products, noting improvements in hair surface properties and color retention when integrated with conditioners.

This study reports that α-casein in bovine milk can form stable complexes with zinc, potentially useful for fortifying milk-based products to enhance zinc availability.

In this study, hair follicle neural crest stem cell-derived exosomes, especially those overexpressing miR-214-3p, significantly promoted axon extension and nerve regeneration in both in vitro and in vivo models, suggesting a promising therapeutic strategy for peripheral nerve injuries.

This study found that exosomes derived from hair follicle neural crest stem cells significantly promoted nerve regeneration in injured neurons, particularly when overexpressing miR-214-3p, which enhanced axon extension and motor function recovery in both in vitro and in vivo models.

This study found that chemically modifying hair with 2-iminothiorane hydrochloride improved the permanence of hair setting without damaging the hair by increasing disulfide bonds.

This study found that A(3)B(5) downregulates melanin production and suppresses melanoma cell growth by promoting proteasomal degradation of TRP-2.

This study found that nanoplastics' aggregation behavior on human skin, influenced by factors like concentration, photoaging, and organic constituents, affects their penetration potential through sweat glands and hair follicles, highlighting potential dermal exposure risks.

This study found that a dopamine-methacrylated hyaluronic acid hydrogel enhances the efficacy of adipose-derived stem cells in promoting skin regeneration, potentially involving the Notch signaling pathway.

This research found that the transfer reaction catalyzed by human plasma and guinea pig hair follicle transglutaminases aligns with a ping-pong mechanism involving peptide-bound glutamine.

This study found that a new-type artificial xenogenic derma exhibited better biocompatibility and dermal tissue regeneration ability compared to cross-linked acellular dermal matrix in a mouse model.

Human hair keratin has a 40% α-helix structure that changes to a random coil in 8 M urea.

In a study on wound healing, researchers described injectable POEGMA‐DA hydrogels as a promising non-toxic alternative to traditional wound closure methods, showing effective tissue adhesion and enhanced regeneration of skin structures in a mouse model without significant inflammation.

This article reviews the regulation and roles of spermidine/spermine-N(1)-acetyltransferase (SSAT) in polyamine metabolism and its potential as a target in cancer and other diseases, without reporting new experimental results.
