I did this 2 separate times.

The first time I tried it after washing for maybe about 30 minutes. Nice waves.

BUT I tried this over night, and disaster. My arm pit length hair shrunk to a chin length. My head was full of unnatural looking Shirley Temple curls that wouldn't loosen even when I ran my hands through them. They separated and my hair became super full and really poofy and big. And the back accidentally got wet again after all of it had dried and it ended up being straight as a board contrasting with the above. I tried gels and such to smooth it down but it was a HUGE mess. I ended up going ponytail and rewashing later when I had time.

I wonder if I did something wrong?
