Start with a hair section that is 2 inches (5 cm) wide and no more than a half inch (1.25 cm) thick. Open the iron and place a hair section between the two hot plates, close to the scalp. Trap hair between the plates by firmly squeezing the handles together. While maintaining the tension, slowly pull the iron down along the hair section toward the end. At the end of hair section, release the pressure on the handle and allow the hair to slide out. Repeat process on additional sections of hair until you achieve the hair style you desire. It may be necessary to repeat process on certain areas, depending on the texture of your hair. Some experience is necessary when learning to use this flat iron. After using the iron several times, you will learn the ideal way to straighten and style your hair easily.
