The flex rods were not a success. But don’t worry, it was my fault. I did it midday without thinking: “Am I really going to sleep on these things?” Plus, I rolled them so tight, they were giving me a headache. So I unrolled them and of course my hair was not dry. It was poofy and frizzy so I had put a kerchief over it and called it a day.
I’m not too disappointed, I can try it another day and sit under a drier or something. These are the experimental things you must try in order to see what works for you. You know the saying: “Can’t make an omelet without breaking a few eggs.”
