Liquid Keratin Keratin Super Straight Shine Serum is a three-in-one keratin hair serum for professional control of wavy, curly, and frizzy hair. The silicone-free formula uses a Keratin Protein Complex with hydrolyzed keratin and keratin amino acids to smooth the cuticle, support straighter, shinier results, and help maintain body and bounce. Thermal heat protection up to 450°F supports daily use with flat irons and blow-dryers in salon settings. The serum is paraben-free and phthalate-free, helps reduce visible frizz for days, and is suitable for damp or dry hair to polish and manage ends without heavy buildup. Read more
