This study found that unsaturated fatty acids are more abundant in the cortex of human hair than on its surface, and steryl glycoside-like lipids may help bind the cuticle to the cortex.

This study observed that repeated perm treatments decrease disulfide bonds in hair due to their conversion largely into cysteic acid, affecting the waving efficiency depending on the reduction agent used.

This study observed that lipids in human hair accumulate in specific areas and do not significantly impact water permeability, highlighting the utility of AFMIR for studying complex biomaterials.

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 found that white hair fibers have lower lipid content and different water absorption dynamics compared to brown hair fibers, suggesting differences in their barrier functions.

Finasteride's polymorphic form affects capsule quality and drug effect, requiring strict control.

This study provides conclusive evidence of exogenous calcium fatty acid deposits forming between the cuticle layers in hair, affecting its optical and mechanical properties.

In this study, UVB exposure was found to alter certain chemical properties of the hair shaft, such as keratin components and water content, without significantly affecting its physical morphology.

This study described a new wig coating technique using keratin and graphene oxide that significantly enhanced UV resistance, antistatic properties, and durability compared to traditional methods.

This study found that monoethanolamine-based hair color formulations caused significantly more damage to hair than ammonia-based formulations, especially at high concentrations.

A new, quick method accurately detects minoxidil in drugs and cosmetics.

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.

In this study, researchers developed a method called the Stiffness-Angle Law and found that hair treated with caffeine-infused shampoo showed a 13.2% increase in stiffness, as measured by their novel evaluation technique.

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.

In this study, researchers developed a new wound dressing material using chemically modified Isabgol with antibacterial properties, which showed promising biocompatibility and effectiveness in managing chronic wounds by preventing infections and maintaining a moist environment.

This study identified that Mangkokan leaf extracts contain active compounds such as alkaloids, flavonoids, steroids, tannins, phenols, and saponins, using different solvents and FTIR analysis.

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.

This review discusses the potential of using human hair proteomics for non-invasive diagnostic and forensic applications but reports no new results; the authors highlight areas needing further research.

In this study, researchers developed and tested an herbal antidandruff shampoo using plant extracts like neem, fenugreek seed, aloe vera, and clove, demonstrating antibacterial and antifungal activity against common scalp microbes and offering a potential natural alternative for dandruff treatment.

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 reported that pentoxifylline-loaded liposomes, optimized using a statistical design method, achieved a maximum encapsulation efficiency of 84.23% and a controlled 72-hour drug release, potentially improving therapeutic delivery of the drug with limited bioavailability.

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 quercetin-loaded solid lipid nanoparticles demonstrated positive protective effects on human hair against UV-B light, as they controlled microscopic surface roughness, reduced chemical changes, and minimized protein loss in vitro compared to other treatments.

In this study, researchers observed that even a single session of hair dyeing can damage hair fibers, with significant worsening of mechanical properties and protein composition after three or more consecutive treatments, emphasizing the need to consider the cumulative impacts of dyeing on hair health.

In this study, a bleaching protocol was developed to evaluate hair repair products, revealing that K18® and Olaplex® improve hair brightness and lightness, with distinct impacts on hair fiber properties.

This study reports that hair oil formulations using Arnica montana in castor and mustard oil bases showed effective results in quality and quantitative analysis through UV visible spectrophotometer, FTIR, and HPTLC testing methods.

This study found that microplastics on the Lebanese Mediterranean coast transport various organic and inorganic pollutants, posing threats to marine organisms and potentially human health.

This research suggests that geometric classification of hair into fewer groups may be more reliable and useful for studying hair characteristics, rather than racial descriptions, especially in medical and forensic applications.

This study observed that the molecular structure of keratins in hair fibres' discrete transition zone differs in breast cancer patients, with altered lipid ester absorption bands reverting post-cancer removal.
