I tried the No Poo. I'm prob not the best judge since I found out that cowashing & conditioner in general aren't for me, but I thought cheapies like V05 Moisture Milk & Suave worked better as cowashes than this. I felt like my hair was no cleaner, but was not as soft or moisturized when compared with the cheapies.
You might get a better idea as to how the product will work on your hair from people with your hair properties, like texture (hair thickness) and porosity. Going by how big/small your curls are is a bit irrelevant.
