Did it work? Instead of a sock, I used Robe Curls, which is the same concept, except instead of a sock, it's a curling headband. (It still requires the exact same technique to be done to achieve the bouncy, heatless curls.) I sprayed my hair with some water to get it a little damp as instructed, parted my hair down the middle and on each side, wrapped my hair section by section around the headband, and secured it with a scrunchie.
Four hours later, I took out the headband, and, to my surprise, my hair was left with a lot of pretty flips and soft curls. It didn't create the same curls I would achieve with a hot curling iron (or the ringlets I've been seeing on TikTok), but I also wasn't mad at the results I got. It was a simple technique to achieve bouncy, flowy, pretty hair without any heat damage. I would definitely try this method again!
