Matrix Opti Effects is a modern dual wave system that creates long-lasting curls in a single use kit, ideal for normal, resistant and colour treated hair.
My hair is fine and whitish (a pretty word for grey). This is the first perm in many, many years that did NOT burn my hair. It leaves a beautiful curl for me that lasts quite a long time. It smells amazing, too. For anyone with fine hair, grey or delicate hair - this is the perfect perm!
