Framesi Professional Activator comes in a blendable formula that mixes well with coloring products to give you the desired shade of color. It provides high-quality, even results without damaging your hair. The odorless, cream-based formula provides you damage free color lifting and toning. The 20 volume developer opens the hair cuticle but unlike 10 volume, it provides lifting of the hair by one to two levels. If you have more than 50% gray hair, 20 volume developer is the only developer to use for 100% gray coverage and a long-lasting color.
