I use it on my towel dried hair, I then twist my hair in a bun and leave it for 10 min or so (I will go smoke a cigarette and let it back down when I am done, ew, I know). When it's done, it makes my hair look great. I have natural waves by the way.
I shower then dry my hair. I usually apply it on dry hair that way I can notice that its making a difference. You put it in and kind of run it through, making the partitions you want with your fingers as the products set. I avoid putting it on the top layer of my hair so it doesn't get that greasy over product look.
I use it when my hair is still dry and then scrunch it when it is damp. another way i use it is when my hair is dry and then wait for the hair to re dry and will then curl it with a wand. i find it gives it added texture
