Quantum TT Purple Ring is an acid perm that provides firm, springy, resilient, long-lasting curls with extra volume and support. The distinctive blue ring in the waving lotion contains a unique blend of vitamins, moisturisers and protein. This fortifying complex provides superior conditioning and allows for more effective and efficient penetration of the hair cortex while preventing cuticle damage. It contains a UV blocker that provides additional protection from colour fading. Quantum TT Purple Ring locks in curl, producing healthier colour-treated hair with excellent shine and manageability.
