I have thick wavy/curly hair and I tried it. It worked pretty well, it just looks a bit messy compared to the video. I'll update after taking it off (and wearing it all day) to see if there are knots or not. Update : I took it off pretty easily, and there are no big knots! I definitely recommend, but make sure to separate your hair well to prevent from knots!
(This is fake) after tieing her hair with rubber she just cropped it and used a claw clip to make it bouncey, and she dint show the left or right side too. This is fake ✖️
