The first night I tried it, uh, it didn't work out. I have a very sensitive head and the headband was killing me. After only about an hour I took it out, but already noticed really pretty curls.
Day 2, I washed and dried my hair and followed the directions in the tutorial. Ignoring the "leave it in overnight" part.
Goofy look #1
Goofy look #2. I know there's a line on my head. I'm trying to be realistic here.
I left the band in for 2 hours in the afternoon and the line in my forehead took about an hour to get rid of... So, plan accordingly. I am going to try these again soon in the morning and leave them in all day.
