Flat Iron and No Heat Curls

There are so many great hair tutorials on Pinterest. I've been trying a few of them out to see how they hold up. Above you'll see how my hair came out using a flat iron to curl it. It worked really well, but even after hair spraying it, it fell flat with in a few hours. Maybe next time I can put more product in it to help it last longer.

I also recently tried the no heat curl tutorial popping up all over Pinterest too. This gave a completely different curl than the flat iron. Instead of leaving mine in all night I just left the headband in my hair for the first few hours of the day. Between the two I prefer the flat iron curls. They gave me more volume and a nice messy look that I really like.

Have you tried any hair tutorials lately? Anything work or not work for you?
