Description Close Donatti Theion Leave-in is a thermo-activated smoothing and protective treatment formulated to maintain and enhance the results of the Theion Professional Kinetic Control System. Enriched with amino acids, keratin, collagen, and natural extracts, it provides intense hydration, thermal protection, and frizz control while keeping the hair smooth, shiny, and lightweight. Its heat-activated technology forms a micro-protective film around each strand, sealing the cuticles and preserving alignment against humidity and environmental stress. The Theion Leave-in also helps repair micro-damage caused by chemical and thermal processes, maintaining the hair’s strength, elasticity, and softness over time. Perfect for daily maintenance or post-treatment care, this product leaves the hair silky, disciplined, and luminous, with a pleasant long-lasting fragrance. It prevents dryness, reduces styling time, and ensures a flawless salon-smooth finish every day. Usage:Apply a small amount to clean, damp hair. Distribute evenly from mid-lengths to ends, then proceed with blow-drying or styling as desired. Do not rinse.
