I also wanted to share a trick that I find quite handy in a pinch to save some time. I found a video that teaches you how to do this hair style here. I do have a few pictures of this process for you. First you start off with an elastic headband that you can put around your head. Your hair should be slightly damp so the hair will wrap and stay a little bit easier. You then start with the front of your hair and piece by piece wrap your hair around the headband until all the hair is wrapped like so. I did add a few bobby pins to make sure that my hair didn't slip out.
Once you have your hair wrapped, spray a little bit of hairspray and go to sleep! This elastic headband and your hair make it really comfortable for sleeping. In the morning, all you have to do is take out the bobby pins and headband, and you will have this!
Note that from the back, my hair is pretty flat at the top from having the headband in and the curls starting that far down my head. To fix this problem, I simply wear my hair half up.
Viola!! It literally takes 10 minutes tops to put my hair in the headband at night and take it out in the morning. Way better than curling it for hours!
