I use mostly Wella's Koleston Perfect ME+ color line, which is designed to minimize the formation of free radicals and to replace extreme sensitizers, PPD and PTD, reducing the risk of developing a new hair color allergy by up to 60%. 

I also use the rest of Wella's color lines, as well as other lines for fashion colors. 

Styling products are fun to mix and match, but I mostly use Kenra, Wella, Sebastian, and Sexy Hair products.
