Keeping my color-treated red hair vibrant isn’t easy - I recently discovered these products which are made with color-treated hair in mind and - after using them for a few months - I am OBSESSED. Every time I wash my hair, I use step 1 (shampoo) and step 2 (conditioner) in the shower, and then I run a quarter-sized amount of step 3 (serum) in my hair after I get out of the shower. In between washes, I apply the step 3 serum to the ends to keep them moisturized. Once a week, I’ll use the mask before washing as usual. Result: hydrated, vibrant hair!
