Hyacinth, I MUST use colonizing products-and I tend to use what my stylist suggests, but he is not one to commit to a line and carry it for years. That being said-and it's no guarantee it will work for everybody, but I am finding that Matrix volumizing mousse works wonders but I apply it AFTER the conditioner.( I am using a leave in by Redkin). Once a week I use a mask that is specifically used for color treated hair by Biolage. It's not heavy at all and you only need to leave it in five minutes before you rinse. After that, I apply the Matrix mousse: if I don't use it, styling my hair is useless. BTW, with this mousse, I can let my hair air dry, then I style it with the Perfector. Poodlepet
