Perfect 10 is the first product to use Clairol's breakthrough formula, which works so efficiently that it does the job in just 10 minutes. The advanced color cream with micropearls allows for fast penetration into the hair fibers. Once inside the hair, the unique combination of effective ingredients targets the natural melanin pigment and deposit the new color without reacting as much with the surrounding hair protein. The complete coloring process is accelerated and we can achieve high gloss color and 100% gray coverage in 10 minutes. Micropearls are the color molecules that exist within Perfect 10's advanced color cream formula. Each shade of Perfect 10 contains a unique mix of different colored molecules and conditioning ingredients to create the desired shade. Perfect 10's advanced color cream with micropearls is what provides consumers with high gloss color in just 10 minutes. Perfect 10's formula is totally different from anything else out there. It's not just about one ingredient--it is the combination of new elements that makes it so exciting. It uses a unique lightening system, which is the heart of any colorant, to prepare the hair and speed up the color reaction, energizing color to move inside the hair, creating beautiful, high gloss color in just 10 minutes. It works at a pH closer to that of hair itself, making it gentler and better protecting the hair surface. It is this total package that makes Perfect 10 the first big color breakthrough in over 50 years.
