Volume??

What do you guys put in your hair to add volume to it? I want that big glamorous hair, but when I do twist outs my hair is flat [You must be registered and logged in to see this image.] and what do you put to help the curls stay defined without frizzing up?

This is what my hair looks like when I do twist outs.

Thanks ladies!

i was wondering this too.. like i can't get my hair to go up

I find that when I do a braidout, over time it just gets bigger haha. I moisturize using not-so watery products; a thick conditioner like Trader Joes Nourish Spa or HEHH and a sealer like shea butter, braid it up in about six/eight sections and after three/four days of doing that, my hair is big and defined with little to no frizz [You must be registered and logged in to see this image.] Plus, my hair gets super stretched, so you can see some length in the braid out too. Not too sure about twist outs though
