Sulfate-free formulations replace SLS and SLES with amphoteric, non-ionic, or amino-acylated surfactants. Hairswiss analyzes the comparative chemistry of these alternatives, their mechanisms of action on the cuticle, and the cases where their use is genuinely justified in a professional context.

Hair Lamination: Chemistry of the Protective Film, Mechanism of Action and Professional Guide
Hair lamination is a cosmetic technique that deposits on the hair fiber a film of film-forming polymers — primarily chitosan, hydrolyzed proteins and cationic polysaccharides — adsorbed by electrostatic attraction onto the negatively charged cuticle. An additive and reversible technique, chemically distinct from nanoplasty and keratinizing treatments. Hairswiss analyzes the mechanisms and active ingredients.
