This thread made me curious, so instead of blowing my hair straight (which I do about every three washings or so because I like variety), I put my hair up in a towel, then took it down to observe what it looked like with no product. Turns out, right now, I'm getting loose beach waves. So I'm experimenting. I put a little mousse in it, and I'm going to see what happens. I suspect it'll wave, but it might frizz once it's dry. I think the gel is what gives me true waves/curls, and fights the frizz. I took a couple of pics of it wet with no product, and I'll put them in my fotki.
