Regenine is a cationic phytocomplex of plant origin — chemically Hydroxypropyltrimonium Hydrolyzed Corn Starch — capable of binding electrostatically to hair keratin to smooth the cuticle, reduce frizz, and reinforce the fiber. Hairswiss analyzes its mechanism of action and presents the professional products that integrate it.

Hair Keratin: Molecular Structure, Mechanism of Action and Professional Use
Hair keratin is an α-scleroprotein whose strength is based on disulfide bonds (S–S) between cysteine residues. In cosmetics, only hydrolyzed keratin — fragmented into peptides of 300 to 10,000 Da — can act on the fiber. Hairswiss explains the exact chemistry, mechanisms of action, and real limits of this essential active ingredient.
Vegetable Keratin: What This Term Really Hides Behind the INCI Chemistry
«Vegetable keratin» does not exist biochemically: it refers to hydrolyzed wheat, soy, or corn proteins, poor in cysteine and therefore unable to reconstitute disulfide bonds. Hairswiss clarifies the difference from animal keratin and explains what these actives actually do on the fiber.
Denatured Alcohol in Hair Care: Chemistry, Risks and Professional Guide
Denatured Alcohol (Alcohol Denat., ethanol C2H5OH, MW 46 Da) is a short-chain, volatile and water-miscible alcohol whose drying effect on the hair fiber results from the solubilization of intercuticular lipids and surface water entrainment by evaporation. Hairswiss analyzes its chemistry, problematic concentration thresholds and professional formulation alternatives.
Boar Bristles in Hair Brushes: Role in Sebum Distribution and Friction on the Hair Fiber
Boar bristles, with a diameter of 50–80 µm and a scaly surface that mimics the hair cuticle, mechanically distribute sebum from the roots to the lengths, reducing tip dryness without any product addition. Hairswiss analyzes the physics of brushing and the interaction between bristle fibers and the hair fiber.
