The video features a woman with long black hair demonstrating how to use a curling iron. She starts by sectioning off a small portion of hair and then twists it around the barrel of the iron. She then heats the iron and holds it for a few seconds to curl the hair. The woman repeats this process with the remaining sections of hair until all of it is curled. Throughout the video, she provides step-by-step instructions and tips on how to achieve the perfect curl.
