Well, there are two choices. For fine thinner hair use Herbal Essences for colored hair, but for coarse thicker hair ( especially for african-americans) Pantene makes a line specifically for women of color who color their hair.
I use JOICO's Color Endure collection, it's a purple bottle that squirts out purple shampoo. It keeps your color in without making it look brassy or faded. I would prefer you to go to ULTA or go to ULTA.com. They have a vast variety of products for you to choose from especially for your dyed hair.
