Several companies launched new hair care ingredients in 2011 to improve conditioning, color retention, combability, and heat protection.

In this study, cinnamic acid in solution form showed strong antifungal activity against Microsporum canis, but when incorporated into hydrogels, the acid's diffusion and resulting antifungal performance decreased, though it maintained effectiveness for potential prolonged exposure.

This study found that the new cocrystal formulation KET-PABA improved the antimycotic efficiency of ketoconazole and induced an anti-inflammatory response without causing skin sensitization in mice.

This study evaluated a new nanogel formulation containing Ciclopirox Olamine for treating cutaneous candidiasis, finding that the optimized version offered improved skin penetration, sustained drug release, and effective antifungal action against Candida albicans compared to conventional treatment.

In this study, cell membrane remodeling with a thermoresponsive boronic acid copolymer was shown to rapidly form spheroids from cancer or cardiac cell lines under standard conditions, promising advances in tissue engineering.

The researchers reported that zinc carbonate nanoparticles stabilized with polyvinylpyrrolidone did not show local irritant or skin-resorptive effects in preclinical tests on rabbits and rats.

This source highlights the utility of cationic polymers in haircare products for protecting against hair damage from chemical treatments and grooming, and describes how microfluorometry can measure polymer deposition and penetration on hair fibers.

In this study, the combination of biologically engineered hyaluronic acid and polyquaternium-10 improved hyaluronic acid's retention and moisturizing effects on hair by forming a stable complex that increased binding affinity to keratin.

Made 8 minoxidil samples; 1 cocrystal, 7 salts formed.

In this study, fluorescence microscopy revealed that a cationic cellulose ether derivative adsorbed onto hair fibers desorbed significantly when treated with sodium dodecylsulfate.

In this study, carboxymethylalanyl disulfide keratin was shown to effectively prevent hair damage during repeated bleaching and permanent waving treatments.

A new method strengthens hair without using harmful chemicals.

This study describes the development of a minoxidil gel using the copolymer Sepineo P 600, showing improved spreadability, occlusivity, adhesiveness, and stability compared to minoxidil lotion, without causing skin corrosion, making it a potentially more effective treatment form for alopecia areata.

The optimized Cinchonine gel effectively fights acne bacteria and is safe for twice-daily use.

This study found that RADA-PRG hydrogels enhanced skin-derived precursor cell proliferation and improved hair follicle neogenesis in mice, suggesting potential use as a scaffold material in tissue engineering.

This research found that immobilizing type I atelocollagen onto artificial hair significantly improved the adhesion and long-term fixation of the hairs in the human scalp, indicating high biosafety and enhanced tissue integration.

Applying pseudoceramide improved skin and hair health.

The researchers reported that hydrogels made from methacrylated glycol chitosan and hyaluronic acid with chondroitin sulfate may be suitable for load bearing soft tissue repair, showing enhanced chondrocyte viability and metabolic activity.

New resin B makes artificial hair fibers hold curls longer than traditional resin A.

This review discusses new developments in understanding the structure and properties of keratin fiber cell membrane complexes, without reporting new experimental results.

This study developed a new suspended ointment formulation containing neomycin sulfate and triamcinolone acetonide, which showed promise for treating neurodermatitis and chronic eczema by ensuring stable composition, effective skin penetration, and no skin irritation.

This study found that modifying biphasic calcium phosphate/poly(methyl methacrylate) bone cement with human hair keratin improves its hydrophilicity, mechanical properties, and supports bone repair in rats, indicating potential for orthopedic applications.

In this study, researchers demonstrated that using cyanoacrylate glue effectively reduces microbial contamination in biopsy samples from the skin surface of wild roe deer, offering valuable insights for human hair follicle microbiome research despite the nonhuman model.

This study investigated the integration of crystal engineering and microneedle technology for androgenetic alopecia treatment, finding that microneedles loaded with newly developed Kopexil multicomponent crystals reduced drug diffusion rates in vitro compared to standard formulations.

This study found that electrospun poly(ε-caprolactone)/poly(3-hydroxybutyrate) blend fibers demonstrated nanometric dimensions and promising properties for drug delivery, with curcumin release linked to fiber morphology and processing parameters.

This study found that dexamethasone-loaded polymeric nanoparticles, particularly those combining ethyl cellulose with Eudragit® RS, may improve controlled release and penetration of corticosteroids into the skin and hair follicles compared to traditional methods.

Polymethylene wax in hair relaxers makes hair smooth and shiny with less damage.

This study found that pretreatment with KP-Cryst fusion proteins effectively protected Asian and Caucasian virgin hair from thermal damage by maintaining higher water content and preventing structural changes during heat application.
