In this in-vitro study, researchers found that shampoo-induced coacervates structurally resemble cationic polymers and contain anionic surfactants that may stimulate the scalp upon exposure to water.

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.

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, the combination of petroleum ether extracts from Jacquinia ruscifolia flowers and Thuja orientalis strobili demonstrated synergistic larvicidal effects against third-instar Culex quinquefasciatus larvae, achieving 100% mortality at 250 ppm with noted synergism particularly in a 1:2 ratio.

This study found that the optimal characteristics for ulin seed oil extraction are fresh, mature, and resinous seeds, and that FTIR spectrophotometry with PCA can effectively detect adulteration of the oil, particularly at certain wavenumbers like 1745 cm⁻¹.

This study found that hair from ovarian teratomas shares similar chemical composition and morphology with scalp hair, but differs in physical properties and cysteic acid bands.

This study found that ATR-FTIR spectroscopy combined with machine learning effectively differentiated alopecia areata patients from healthy controls with an AUC of 0.85, and also showed promise in predicting treatment response, particularly through alterations in the Amide I band.

This study successfully used ATR FT-IR spectroscopy to uniquely identify or differentiate human hairs by detecting specific spectral features associated with individual hair characteristics and cosmetic residues on hair surfaces.

This study used phytochemical screening and FTIR spectroscopy with PCA to reveal slight chemical differences between two varieties of Eclipta alba, providing a method for their effective discrimination.

This study explored a multidimensional approach to examine body hairs' physico-chemical properties, potentially supporting their use over scalp hairs in forensic and intoxication studies.

This study observed that the aqueous extract of roasted Alocasia macrorrhizos tubers led to hair follicle repigmentation and reduced epidermal thickness in a murine model of Vitiligo.

In this study, researchers found that minoxidil is compatible with excipients such as Beta-cyclodextrin and cellulose, while it is incompatible with Eudragit S 100 and mannitol, indicating potential formulation challenges in pharmaceutical applications.

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.

This study reports that a Rutin-loaded nanophytosomal formulation with improved physical stability can enhance the bioavailability and antioxidant property of rutin for use in food and pharmaceutical products.

In this study, hair samples from breast cancer patients showed increased β-sheet structures and lipid content, with spectral markers successfully identifying cancer in a blind test but also producing false positives.

This study concluded that bleach treatment partly transforms the hydrophobic top layer of human hair cuticles into a hydrophilic surface with clustered cysteic acid, visualized at the nano-scale using dynamic Chemical Force Microscopy.

PEVs effectively deliver minoxidil through skin.

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.

This study reported that the calculated and experimental electronic and vibrational properties of minoxidil were in good agreement, providing detailed insights into its molecular structure and thermal behaviors.

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.
