Here is a step-by-step tutorial on how to curl short hair with a flat iron:

1. Section off your hair into three or four sections, depending on how thick your hair is.
2. Wrap 1 and 1/2 inch strands of hair around the iron away from the face.
3. Use the iron like you would normally until halfway down the hair shaft. Then, flip the iron over to begin curling the hair.
4. Point your flat iron tip away from your face and take a small section of hair in the middle.
5. Bring the flat iron to the top of the hair piece close to your scalp.
6. Begin turning the flat iron slowly away from your face.
7. The direction of the curl will be away from your face and will create the effortless wave curls we are trying to achieve.
