Polyquaternium: Chemistry of Cationic Polymers, Mechanism of Action and Role in Hair Care

Polyquaterniums are water-soluble cationic polymers whose positive charge allows them to adsorb electrostatically onto the negatively charged hair cuticle. Polyquaternium-7, -10, -32, -37, -55: each number designates a distinct chemical architecture with different film-forming, antistatic and conditioning properties. Hairswiss analyzes their molecular mechanisms and how to identify them in an INCI list.

Capillary Oxygen Therapy: Follicle Biochemistry, Vasodilatory Actives and Professional Analysis

Capillary oxygen therapy is rooted in the vascular physiology of the hair follicle and the biochemistry of mitochondrial oxidative phosphorylation. Vasodilatory actives — menthol (TRPM8 receptors), caffeine (PDE inhibition) and niacinamide (NAD⁺ precursor) — indirectly improve follicular oxygenation by increasing perifollicular microcirculation. Hairswiss analyzes the molecular mechanisms and scientific limits of these protocols.

Hairspray: Chemistry of Film-Forming Resins, Hold Mechanism and Professional Guide

Hairspray is a dispersion of film-forming resins — primarily VP/VA copolymers or acrylates — in alcoholic or aqueous suspension. On drying, these resins polymerize on the hair surface and create a rigid network that holds the style. Hairswiss analyzes the exact chemistry, the differences between gas-propelled and eco pump formulations, and professional selection criteria based on fiber type.

Hair Mousse: Chemistry of Film-Forming Foam, Mechanism of Action and Professional Guide

Hair mousse is an air-water emulsion stabilized by foaming surfactants, whose action relies on the deposition of film-forming polymers on the hair fiber during drying. Its effectiveness in terms of volume, hold and definition depends directly on the polymer type, its concentration and the presence of plasticizers. Hairswiss analyzes the exact chemistry and professional selection criteria.

PEG-7 Glyceryl Cocoate: Chemistry, Role and Use in Hair Care Formulations

PEG-7 Glyceryl Cocoate is a non-ionic surfactant with dual function: wetting agent and hydrophilic emulsifier (HLB ~10–12) derived from coconut oil by ethoxylation with 7 ethylene oxide chains. Widely used in sulfate-free shampoos as a mild wetting agent, it improves the distribution of anionic surfactants without increasing their cuticular irritation. Hairswiss analyzes its molecular structure and formulatory role.
