In the landscape of professional hair care actives, few ingredients attract as much attention as Regenine. Presented as a natural conditioning phytocomplex, this active ingredient sits at the heart of intensive regeneration protocols now used in professional hair salons. But what do we actually know about its chemical composition, its mechanism of action, and its real benefits for the hair fiber? Hairswiss breaks it down.
What Is Regenine? Definition and Botanical Origin
Regenine is a conditioning phytocomplex of natural origin, obtained primarily through enzymatic and chemical modification of plant polysaccharides — specifically from corn starch (Zea mays). At the INCI level, it corresponds to the designation Hydroxypropyltrimonium Hydrolyzed Corn Starch: a cationic molecule based on hydrolyzed starch, quaternized to give it a strong affinity for negatively charged hair keratin.
Quaternization is a key step: it involves introducing a positively charged quaternary ammonium group into the polysaccharide chain. It is precisely this cationic charge that allows the molecule to spontaneously adsorb onto the surface of the hair fiber, which is naturally anionic (negatively charged), through electrostatic attraction.
Chemistry of Regenine: Molecular Structure and Mechanism of Action
From a chemical standpoint, Hydroxypropyltrimonium Hydrolyzed Corn Starch belongs to the family of quaternary cationic starches. The base structure is a polysaccharide (amylose and amylopectin from corn starch), hydrolyzed into controlled-size fragments to optimize penetration into the cortex, then functionalized with hydroxypropyltrimethylammonium groups.
This molecular profile gives Regenine three fundamental properties:
- High substantivity: the molecule remains bound to the hair surface even after rinsing, forming a durable protective film that reduces friction and static electricity.
- Biocompatibility with keratin: the hydrolyzed polysaccharide fragments interact with the peptide chains of keratin, helping to fill lacunar zones in the cortex — a mechanism known as structural biomimicry.
- Film-forming effect: by depositing on the cuticle, Regenine smooths lifted cuticle scales, reducing porosity and improving inter-fiber glide.
In professional formulations, Regenine is typically combined with hydrolyzed keratin, amino acids, and hyaluronic acid (sodium hyaluronate) for a synergistic action: while Regenine reconstructs the surface and smooths the cuticle, hydrolyzed keratin penetrates the cortex to fill structural voids, and hyaluronic acid restores intrafibrillary hydration.
Concrete Benefits for the Hair Fiber
- Breakage resistance: by reinforcing cuticle cohesion and partially restoring the cortex, the hair fiber gains elasticity and better withstands mechanical stress (brushing, heat, chemical processes).
- Frizz reduction: the cationic film deposited on the surface neutralizes electrostatic charges responsible for uncontrolled fiber swelling, particularly in humid conditions.
- Shine and smoothness: the flattened cuticle reflects light better. Formulation studies show a measurable increase in gloss from the very first application.
- Easy combing: reduced friction between fibers makes detangling easier and decreases comb breakage — a benefit particularly valued on curly and afro-textured hair.
- Post-technical compatibility: Regenine is particularly recommended for hair weakened by bleaching, repeated coloring, or chemical straightening — situations where the cuticle layer is partially destroyed and the cortex is exposed.
Professional Products Containing Regenine Available on cliCHair
Among the professional formulations that integrate Regenine as a central active, two references stand out on cliCHair.ch, the B2B platform dedicated to Swiss hair professionals:
1. Regeneration Therapy Treatment — Edelstein
The Regeneration Therapy Treatment by Edelstein is packaged in bipartite vials (Vial 1: Fluid + Vial 2: Booster), an extemporaneous mixing system that guarantees the stability and maximum efficacy of the actives right up to the moment of application.
The Vial 2 (Booster) concentrates Regenine precisely in the form of Hydroxypropyltrimonium Hydrolyzed Corn Starch, combined with Aloe Barbadensis Leaf Juice, acidic fruit extracts (Pyrus Malus, Citrus Limon, Hydrolyzed Grape Fruit), and Hydrolyzed Wheat Bran — a fruit acid complex (AHA) that optimizes pH and promotes cuticle closure after treatment.
The Vial 1 (Fluid) delivers hydrolyzed keratin and Sodium Hyaluronate, which penetrate the fiber during the processing time to reconstruct the cortex and restore hydration.

2. Regeneration Therapy Master Kit — cliCHair.ch
The Regeneration Therapy Master Kit is the complete system designed for salons wishing to integrate a hair regeneration protocol into their technical service menu. It includes the Regeneration Therapy Treatment vials, the preparatory shampoo, the finishing mask, and the Argan Native Fluid — an Argania Spinosa oil enriched with keratin amino acids that seals the cuticles in the final step and guarantees lasting shine.
This kit is designed for hairdressers who wish to offer a high-value service, particularly suited for clients whose hair has been weakened by frequent bleaching or coloring techniques.

Regenine and Keratin: A Complementary Synergy
It is important to understand that Regenine is not a substitute for keratin — it is its indispensable complement. Where hydrolyzed keratin acts deep within the cortex (reconstruction of internal matter), Regenine acts on the surface (protection and smoothing of the cuticle). Both actives operate at different structural levels of the hair fiber, and their combination produces a full-spectrum reconstruction effect that neither could achieve alone.
This synergy explains why professional treatments with Regenine deliver visible results from the very first application: the fiber surface is immediately smoothed and protected, while internal reconstruction is progressively consolidated with subsequent applications.
Hairswiss closely follows the evolution of hair regeneration actives used in Swiss and European salons. Regenine represents today one of the most promising phytochemical innovations in the professional sector.
