What is the best Organix shampoo to use?

I'm trying to look for a new shampoo to use. Right now I have KeraCare Dry and Itchy scalp, which works well on dandruff( Because I have psoriasis on my scalp) but is not sulfate free which dries out my hair. I've used Organix Tea Tree Shampoo and Conditioner. I loved the scent and my hair wasn't as frizzy. Which is the best Organix shampoo to use for moisture and strength. I was looking at buying the Moroccan Argan Oil Shampoo and the Coconut Milk Conditioner. Is that a good combination?
