Hair type matters very little when choosing ingredients/products. It's more hair properties.
Many of us start with Deva, think we like it and then move on to other things that are better for us. Many of us also rotate products. My hair always satiated--even back in the shampoo/conditioner only days. I wet, use a rinse out and style every day. Seldom let myself use any one product more then once every five days, if that.
It's a trial and error process to find the right products that your hair likes. You have to compensate for the dewpoints and get the protein/moisture balance right. My hair started out as winter wavy/summer 3a. I've learned what my hair likes and what works for me. Now it looks like my signature picture all year around.
