No heat curls are created by wrapping the hair around a piece of fabric (a rag, a hair tie, or even a sock) and rolling it up towards the head before securing the ends and leaving the makeshift rollers in overnight. The next day, the strands are undone and styled to maintain the bouncy texture and enjoy the lasting results.

Hair and lifestyle blogger itzamelika tries out different tools for her heatless curls to see what works best and what’s not worth the effort. Her fans share her enthusiasm and join the content creator on her journey to perfect curls.

Lika uses rod-shaped pieces of aluminum foil to create pin curls on either side of her head. The flexibility of the material allows her to pin her hair effortlessly. The curling method has earned the TikTok creator 19 million views and luscious curls, but there’s a catch.

While the end result is stunning, the foil is extremely damaging to the scalp. The blogger confesses that she had to get up at 4am to remove the foil, as it is impossible to sleep with it on. So she advises against trying this curling method at night.
