I have used few sulfate-free shampoos and every time they leave a greasy patch on my crown. I tried rinsing and massaging very long, but still it happens. I tried to switch conditioner many times, some without silicon, some with. And nothing!! Then I went back to my sulfate shampoos and the problem was gone. I wash my hair maybe 2 times a week, sometimes more. I also like to wear my hair straight sometimes, because I love it way more that way. When I wear it straight, the greasiness is more visible.

I feel like maybe I am not getting everything from my curls when using sulphate shampoos. Do I have to just deal with the fact that I need some sulfates in my shampoo?
