Electrokinetic analysis reveals common conditioner ingredient interactions with human hair. [PDF]

Int J Cosmet Sci
Novel electrokinetic analysis reveals how cationic surfactant deposition on hair is influenced by chain length and counterion mobility. Longer‐chain surfactants show superior adsorption through enhanced van der Waals interactions, while chloride counterions enable stronger electrostatic interactions.

Synthesis of a new amino acid derivative with long-lasting hair shape control effects and elucidation of its mechanisms. [PDF]

Int J Cosmet Sci
We have discovered 2‐(2‐aminoethylthio) succinic acid with a long‐lasting hair shape control effect. We have demonstrated its hair straightening and curl retention effect, and clarified its mechanism. Abstract Objective Hair is a crucial aspect of an individual's physical appearance.

Indirubin as a red hair Colourant from Indigofera tinctoria L. [PDF]

Int J Cosmet Sci
An immediate stable red colour result after application of Indigofera tinctoria L. on hair in the presence of isatin and a reducing agent was achieved. A revised indigo molecule and indirubin synthesis pathway for I. tinctoria L. application including the effect of said additives to the colour outcome is presented.

Impact of Diagenetic Alterations on the Petrophysical and Multiphase Flow Properties of Carbonate Rocks Using a Reactive Pore Network Modeling Approach Impact des altérations diagénétiques sur les propriétés pétrophysiques et d’écoulement polyphasique de roches carbonates en utilisant une modélisation par l’approche réseau de pores

Oil & Gas Science and Technology, 2012
Sedimentary reservoir rocks generally have complex and heterogeneous pore networks that are related to the original depositional rock texture and subsequent diagenetic alterations. Such alterations are in part controlled by the original mineralogy and

Effects of repeated exposure to ozonated water on hair fibre structure and integrity: Part I

International Journal of Cosmetic Science, EarlyView.
Repeated exposure to ozonated water caused cumulative oxidative changes in hair, altering structural integrity, thermal behaviour and mechanical properties. The findings reveal a distinct ozone‐induced damage profile that progresses beyond the cuticle, challenging claims of hair‐revitalizing benefits. Abstract Objective Ozone has recently been marketed

Impact of ultraviolet radiation‐induced damage to hair fiber integrity: A multi‐technique physicochemical characterization of surface and cortex properties

International Journal of Cosmetic Science, EarlyView.
UV exposure induces cuticular and cortical damage in natural hair, with oxidative effects and protein degradation comparable to bleaching. However, double bleaching leads to significantly greater structural degradation, emphasizing distinct mechanisms and severity of chemical versus UV‐induced damage. Abstract The combination of chemist techniques is a

Targeted keratin repair: A plant‐based approach to hair strength and surface restoration

International Journal of Cosmetic Science, EarlyView.
Application of Avena strigosa seed extract may reinforce keratin bonding, restoring hair fibre integrity by promoting intramolecular interactions at damaged sites of keratin proteins. Abstract Objective Chemical and thermal stress disrupts the intramolecular and intermolecular interactions that stabilize hair keratin, leading to structural degradation ...
