PUREOLOGY Safe Gard Your Colour Super Straight Relaxing Serum 5.1 oz is a high-performance, leave-in thermal smoothing serum engineered to tame stubborn frizz, relax unwanted curl patterns, and create mirror-like sleekness on color-treated hair. Powered by Pureology’s signature Antifade Complex® and a specialized blend of Camellia Oil, Sesame Oil, and Shea Butter, this silky serum seals the hair cuticle to lock in straight styles while creating a moisture barrier against humidity. It delivers thermal protection against flat irons and blow-dryers while preserving color vibrancy and tonal depth.
