How to apply: Step 1: To activate the auto curler, press the power button. A blue light will flash. Then, press the power button to select the temperature (350, 400, or 450¨H). The temperature has been reached when the indicator light remains on. Step 2: Insert a hair handle at a 45-degree angle into the barrel's gap, making sure the hair does so. To activate the rotating roller, press either the left or right button. The roller will then start to automatically grab and curl hair. Step 3: Press the left and right switches repeatedly until the hair completely encircles the barrel. Release the button and let the barrel heat up and curl the hair once the hair is around it. Step 4: To release gorgeously curled hair, guide the curler straight down after the hair has been curled. Repeat from above.
