I've found that Matrix Kickers tend to boost up the red lights a little...but they still fade....the best reds I've used are from Wella Koleston Perfect....they are bright and vibrant and really mesh well with the natural tones in the hair. Of course the best results are obtained with the proper Wella S'poo and cond....One day clients will realize that Suave doesn't make their hair fabulous...lol. Until then...
