This study found that bleach treatments significantly increased hair surface roughness and decreased Young's modulus, indicating marked changes in hair's molecular structure which may affect future hair-care product formulation.

This study reported that albino Wistar rats exposed to chemical hair straighteners showed significant hair fiber damage and scalp skin deterioration, which worsened with repeated and prolonged application, highlighting the cytotoxic potential of these products and potential systemic risks.

Ethanol spreads well on hair at low humidity but less so at higher humidity due to water condensation.

This study suggests that after perm treatments, sufficient application of keratin and ceramide after middle rinsing enhances curl formation while considering hair health.

This study found that applying a keratin solution improved tensile strength, reduced absorbance, and increased gloss in damaged hair compared to untreated hair.

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

This study found that treating hair with 1 M sodium hydroxide increases its self-friction coefficient, suggesting potential applications in forming fine frictional fibers for medical uses.

This study explored the potential of human hair keratin as a filtration material, finding that it may effectively absorb the pollutants diclofenac and perfluorobutanesulfonate. The researchers reported significant binding affinities through molecular simulations, supporting further investigation into keratin's use for water purification.

This review re-examines hair blowouts as a material science process, where water acts as a plasticizer altering keratin's glass-transition temperature, allowing for temporary hair shaping through a moisture-induced matrix state change under heat and tension.

This research investigated how moisture absorption impacts human hair structure, finding that moisture sorption kinetics reveal insights into chain entanglement and structural changes due to cosmetic treatments, while also quantifying the influence of sample weight and fiber density on the sorption process.

This study observed that hydrophobic modifications of hair matrix proteins significantly alter the humidity-dependent glass transition temperature of human hair.

This review discusses the history and composition of permanent hair waving products for different hair types and reports no new research findings.

This study found that low-molecular-weight hyaluronate significantly improved the mechanical strength and elastic modulus of overbleached hair by enhancing hydrogen bond networks within keratin.

This study found that hydrolyzed wheat proteins extensively penetrated both untreated and chemically treated hair, primarily occupying areas like the endocuticle and cortex.

In this study, a polyherbal shampoo formulated with extracts of Reetha, Fenugreek, and Nagarmotha was evaluated for its physicochemical properties, showing effective dirt dispersion, high foam stability, and satisfactory washing capacity, though further research on stability and safety is needed for commercialization.

This study reviews the potential to repurpose human hair waste, often discarded from places like barber shops and hospitals, into valuable raw materials for chemical and materials science applications, despite existing challenges in its utilization.

This study introduces a new device for measuring changes in hair stiffness and lubricity, which can help predict the effects of various hair treatments.

This minireview summarizes current strategies using superwettable bio-interfaces for wound care, focusing on managing biofluids, and offers insights for designing advanced materials in this field, but reports no new clinical results.

This study found that bio-based waterborne polyurethanes derived from castor oil may offer effective hair-styling performance without skin irritation and appear to be safer for the environment compared to traditional hair sprays.

A mutation in the KRT74 gene causes tightly curled hair.

In this study, adding conditioning agents PA1, PA2, and PA3 to light blonde oxidative hair dyes improved combability and protein retention of light brown hair without affecting tensile strength, though PA1 and PA2 offered enhanced thermal protection.

In this study, formulations of a typical lotion shampoo with ethanol or propylene glycol increased the in-vitro release rate of zinc pyrithione, an anti-dandruff agent.

This study found that repeated exposure to ozonated water caused oxidative changes in hair proteins, lipids, and pigments, leading to altered hair properties, with minimal effects on shine and color.

Created material boosts hair growth and kills bacteria for wound healing.

This study found that repeated cycles of wetting and blow-drying hair fibers can cause cracks in the hair cuticles, particularly among individuals who frequently blow-dry their hair.

This study found that a hair care treatment using integral silk proteins and linseed-derived polysaccharides effectively protected and repaired bleached and colored hair swatches, significantly improving their resistance, luster, and reducing structural damage after chemical treatments.

This study found that two shampoos with different dyeing methods had varying abilities to dye hair and impact hair health, suggesting that individuals should select hair color shampoos based on their personal needs.

This study found that after four weeks of daily use, the roughness of the hair surface significantly decreased, as shown through quantitative image analysis using HIROX.

This review discusses the chemical processes involved in hair styling and straightening and reports no new results; the authors highlight pregnancy safety with hair treatments during pregnancy.

This paper examines factors affecting the stretching setting treatment of human hair and wool, concluding that the intended outcomes can be achieved using their customized testing equipment and technology.
