What is an good shampoo for dandruff and color treated hair?

I was told yesterday in the Emergency room (stomach virus)by the nurse who used to be an hair stylist to never buy shampoos from Walmart. Now I have never bought shampoos from Ulta but have from Sally's. I don't know if those two stores have good shampoos or not.

I am looking for an shampoo for dandruff and color treated hair like all in one if they make such of thing. I do have thick hair,if that helps. I read online that head and shoulders are good for dandruff,but they sell that in Walmart. I don't think my dandruff is that bad at all,but I do find kinda flakes in my hair at times.

I was looking at the shampoo Kendra from Ulta. Is that an good shampoo? Post your favorite shampoo 👇 in the comments section please!
