What would you recommend for a high end or just good quality shampoo and conditioner?

This is my hair air dried after washing with suave professionals. I know, crappy products. My curls can be (and have been before😞) much more defined and less frizzy. From my research I understand sulfate and silicon free products work best?

I’ve used devacurl. It was alright. Just wanting to test other brands.
