Matrix makes a shampoo and conditioner for colored hair, and they also make a voluminous shampoo and conditioner for colored hair. My stylist sold it to me and I swear they really extended the life of my hair color! You can get these are Walgreens or CVS!

Pantene I have found are the best and if you go to Tesco they're usually on offer so you dont have to pay outrageous prices for them.
Loreal Elvive Colour Protect is good
The only one I think kinda works is Tresemme.
