The versatility of hair-straightening appliances allows for multiple uses, including creating waves in your hair. By adding a couple of hair products and a bit of practice, you can have waves for a special occasion by using a hair straightener.
Apply a heat-protectant spray or serum to your hair. Follow the instructions on the bottle to determine how much you need.
Split your hair into sections. Grasp a section with the straightening iron and hold it horizontally at the roots. Flip the flat iron back and forth, 180 degrees each time, while descending to the ends of your hair. Go slowly and flip the straightener in the direction you want your hair to wave in.
Work towards the back of your head and do the same for the other side.
If you do not get the desired results, try again after your hair cools.
Apply hairspray to hold your hair in place, if desired.
A high heat setting on the straightener might be needed for long-lasting waves. Experiment with waves by holding longer for more structure or less time for more relaxed waves. The direction in which you turn the straightener will change the results as well.
Using a straightener on your hair can cause dryness and split ends, so condition your hair and don't heat-style every day.
