Read the directions prior to use. This is to help keep your blonde hair from turning that brass color, for the price its good. The treatment is a purple color, as shown on the bottle. You need to leave on at least 3 mins and it's only supposed to be used weekly.

I don't feel that this was effective at all. After lightening my hair for the first time in years, it was a little brassy and this seemed like a quick, convenient option to tone it down just a little. It smells good and is an okay conditioner, but those are the only positive things I can say.
