I have purchased numerous hair color brands in the past. My hair has the tendency to turn red with permanent brown hair color. I purchased the brass free hair color, and although you have to apply it more often due to it being a temporary hair color that washes out with each shampoo, it doesn't turn my hair red!! Worth the little extra, more frequent work!
I have been satisfied from the first use to the latest. It delivers the quality in coverage as well a natural tone. I would say that each product within the Natural Instinct line is great, but the "brass free" produces the best quality. Yes it's my favorite, but buying through the Overtstock helps me to enjoy it all the more
