How to maintain color treated hair?

I've been coloring my hair for 10 years now. I usually just get a base color at the crown and blonde highlights. I maintain it my using products designed for damaged or color treated hair. Its been working out great. My hair is healthy for the most part. My ends tend to dry out more and because of that I have a layered cut. I really like Pantene Pro-V products. I also use a hair polisher with silicone in it to protect my hair from heat. If there is a better method or product, I would love to know more about it.
