Cheapest sulfate and protein free shampoos?

Hi, everyone! I have medium to high porosity, thick and protein sensitive hair. I do use a little shampoo mainly in my roots every 2-3 days, otherwise my hair gets weighed down. Any suggestions of a CG friendly gentle protein and sulfate free shampoo to use this often? Thanks!

I like the As I Am curl clarity shampoo. Sometimes it can be a little too strong so I mix it with a little bit of conditioner. Hope this is useful
