Keeping (multi) Color Fresh

> I have used the Redken Color Extend shampoo and conditioner. It does keep your color from fading fast, but the conditioner didn't do a very good job of removing tangles for me. Wella Liquid Hair has a product called Color Preserver that you put on right after you have your hair colored. It works good. It comes in a really small silver cylinder. Be careful not to let too much out. It forms like a mousse so it grows. My favorite is Sebastian Clear Cellophane. Only licensed hairstylists can get it but it really makes your hair shine and seals in the color.

I just had my hair highlighted with-get this-dark brown, light brown, red, blonde-then when it was all over-another shade of blonde in the front! I am thrilled with the effect-very natural looking! There are loads of products to keep color fresh but they all seem to be color specific. I was wondering if there was any product that keeps color fresh for every color!Thanks,Shannon
