If you have colored your hair with box…
If you have colored your hair with box color...then you know you have to apply it on unwashed hair and leave it on for however long your hair needs to absorb the color! This product worked as advertised since my first application 5 weeks ago! What I like most about this product is there are no obvious fading at my roots; I could probably go another week, but I have business appointments and will not be able to apply for another 2 weeks!! Gotta look good ya know!!
