Heatless waving is a great way to style your hair, as it is better for it and more efficient. Studies have shown that heatless waving is actually better for your hair and lasts longer throughout the day. Heatless waving is simple, you can either do those fancy social media tutorial, which would be more efficient and the waves would be more noticeable throughout the day, but it would be very hard to do. What I would prefer is either braiding your hair overnight or twisting your hair into buns to stay overnight. P.S if you’re going to do overnight waving, use a bonnet or something like that to make sure your hair doesn’t come apart.
