I bought this yesterday and had Darryl put it on my hair, which he hated, and rightfully so, it was very undudelike of him, but how was I supposed to get it in the back? I think the jury is still out on this, I did notice low on the ingredient list that hydrogen peroxide was listed. I can't decide if it worked, or lightened my hair. I'm not super worried about the lightening thing, if it did, it was minor and I kind of have a love of dying it darker anyways, so I can always fix it that way. Eh, we'll see how my hair looks the next few days, it was only $8.
