My daughter is OBSESSED with heatless curlers these days. Although she has incredibly beautiful hair as is, she does not love the fact that her hair is wavy only in the back. Therefore, she likes to have it curled most days, to look more polished and even. That said, she is aware (probably from my complaining) that curling your hair is not good and can damage your hair due to the heat. So, she found online, (thank you TikTok), heatless curlers. It is easy, simple, cheap, and SUPER effective.
I am sure that it will be a fad for only a short time, but regardless, I am a fan because it is safe for the hair, easy to do, and looks great in the end!
