A Powder and a liquid, one is the "color", the other is the accelerator. I can't even tell you how happy I was with the results of it. (Directins are two scoops of each, I am only using one half scoop of each. I dont' need to be making a large batch of it.) Best thing I have used. I bought the reducer, was a bit diassapointed with it, course, that could just be me. So far I have loved EVERYTHING I have purchased and that has been alot of products. I refuse to use anything else now except the Pet Silk line.
