Plug the iron into an outlet, preferrably near a mirror and adjust it to medium. You may decide later that you need a higher or lower temperature.
Gather the top half of your hair and secure it with a clip at the top of your head.
Taking small sections of the hair hanging loose, clasp the iron on them close to your scalp.
Then pull it from top to bottom counting approx. 2 seconds for each part of your hair.
Repeat this process, letting down the hair you originally clipped up and ironing that too until you get that sleek hair you've always wanted!

Hope this helps hun.
