This study explored using keratin extracted from human hair waste to create biodegradable bioplastic films, revealing promising potential for applications in packaging and disposable items due to their uniform surface morphology and ability to degrade with keratinophilic fungi.

In this study, extracts from Chenopodium quinoa, Glycine max, and Malpighia emarginata demonstrated stability, low toxicity, and effective cleaning potential as surfactants in shampoo formulations, showing performance similar to or better than commercial shampoos in terms of surface and interfacial tension and sebum removal.

This study developed a new triamcinolone acetonide serum combined with a microneedling device, showing promise for treating alopecia areata by targeting hair follicles in a less invasive, patient-friendly way with confirmed drug solubility, compatibility, and safety.

This study developed effervescent cleansing tablets containing asiatic-acid-loaded solid lipid microparticles, finding that they provided effective cleansing compared to water and showed good flow properties, pH, and hardness but were unstable at high temperature and humidity.

This study found that chemically treated hair, particularly when subjected to both acid straightening and bleaching, experiences more significant structural damage when exposed to heat, highlighting key changes in both the internal and surface components of hair fibers.

This study found that permanent waving treatment partially disrupts the α-helical structure in human hair microfibrils, primarily during the initial reduction phase, rather than just affecting disulphide bonds.

In this study, desmopressin-loaded elastic liposomes (ODEL1) showed improved permeation and drug deposition across rat skin by altering the skin's cohesive energies and causing reversible changes on its surface.

Hair removal methods damage the skin barrier and affect substance penetration.

In this study, researchers used advanced infrared microspectroscopy techniques to map the chemical composition of human hair, revealing new insights such as the presence of glycogen in the outer root sheath and the widespread distribution of calcium carboxylates in the hair cuticle.

This study found that a sucrose-based crosslinker can effectively straighten hair and maintain durability in high humidity and through repeated washings without affecting the hair's tensile properties or causing surface damage.

This study demonstrated that cryogelation of human hair keratin allows the development of 3D scaffolds with tunable properties, supporting cell adhesion and proliferation for potential biomedical applications.

This study highlights that lower testosterone in men and higher testosterone in women are linked to increased risks of metabolic syndrome and type 2 diabetes, with associated skin diseases indicating potential cardiovascular complications.

This study presents computational modeling and experimental analysis of the HGT protein KAP8.1, identifying key structural features that may influence hair's response to environmental conditions.

In this study, researchers examined juglone's potential as a restoring agent for hair keratin damaged by permanent or bleaching treatments, finding that juglone formed Michael adducts with cysteine residues, leading to a more regular hair surface as observed via IR spectroscopy and SEM analysis.

This study found that in a rat model, minoxidil promoted better wound healing through potential anagen hair growth effects, while dexamethasone suppressed wound healing by reducing collagen production.

In this study, researchers used pumpkin aqueous extract to create iron nanoparticles, finding them effective at inhibiting harmful bacteria found in burn and wound infections, as well as promoting burn healing and hair growth in a laboratory mouse model.

In this study, researchers developed a coamorphous form of tadalafil and finasteride, showing improved solubility and dissolution in vitro, with results successfully translated in vivo in rats. They reported reasonable stability, suggesting this form could serve as a therapeutic alternative to the current marketed combination.

This study found that selected polymeric pretreatments on hair can significantly reduce breakage and protect against thermal damage from hot flat irons by maintaining cuticle integrity and moisture.

This study observed that a peptide showed higher antioxidant and metal ion chelation activity compared to its encapsulated version cross-linked in calcium alginate beads.

This study found that incorporating CTA2-BADG, a modified hair-rebonding compound, into damaged hair significantly improved surface morphology and tensile strength by using charge-conversion chemistry to enhance penetration into the hair shaft.

This study demonstrated that keratin can be effectively extracted from wool using alkaline solutions and that the extracted keratin maintains reactivity similar to that from other low-value sources like cattle hair.

This study found that improved testosterone measurement using LC-MS/MS in women with PCOS revealed a stronger correlation between hyperandrogenism and insulin resistance than previously detected.

This study identified trilauric glyceride and decanoylcarnitine as potential biomarkers for diagnosing PCOS in patients with and without insulin resistance, suggesting significant metabolic alterations in these conditions.

This meta-analysis confirmed associations between some androgenic and metabolic parameters in women with PCOS, suggesting that these measurements might help predict metabolic risk in this population.

This study reported that metallic-glass-coated tattoo needles reduced trauma and improved tattoo quality in pig skin experiments compared to uncoated needles.

This study found that Carthamus caeruleus (L.) leaf extracts possess higher antioxidant and antibacterial activities compared to rhizome extracts, and are rich in phenolic and flavonoid compounds, suggesting potential use as a natural therapeutic agent.

This review highlights how forensic drug analysis in hair using modern instrumental techniques offers advantages such as easy sample collection and chronological tracking of drug use, emphasizing its value for law enforcement and other applications.

This study demonstrated that dermal papilla cells are molecularly distinct from fibroblasts and identified many novel molecules, including a new member of the CTGF protein family.

In this study, the researchers developed and optimized a curcumin nanocrystal gel to enhance skin permeability, reporting improved dissolution properties and antiproliferative effects on cell lines, suggesting it as a promising topical delivery system.

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.
