If you just detangle your hair well, and just go under the dome dryer, on low 30 min or so, then your hair will look like a blowdry.
I saw it on a youtube video, made a thread asking about it a min. ago, and a couple of ladies do it.
My ends would get frizzy though and TuffCookie was telling me to put rollers on the ends of your hair.
Then you can moisturize a little bit, pincurl or wrap your hair, and do a saran wrap.
ETA- To be exact she was telling me that you can put alittle more leavein, like a dime size, wrap, saran wrap, and go under the dryer on low for about 15min.
I love it.
But I do love blowdrys too, I use the comb attatchment as well and aim down. I cant really accuratly judge how they do my hair because I usually get carried away when I blowdry and do it again soon or use different forms of heat when I usually dont.
