Make Wavy and Frizzy Hair Straight

1. Wash your hair with shampoo and then apply a moisture-enhancing conditioner to the ends and leave it to soak in for five minutes.
2. Brush your hair to remove tangles and to help activate the conditioner and then rinse.
3. Wrap your head in a towel and leave for 15 minutes to allow your hair to partially dry. Blow-drying your hair when it is completely wet can reduce its moisture and elasticity, which can make it frizzy and difficult to style.
4. Dry your hair, ensuring that you brush it regularly into the style you want it to take. Point the hairdryer downward at all times to ensure that split ends and baby hairs aren't roused and they are smoothed down. Plug in your straightening iron while you do this so that it can heat up in time for use.
5. Apply a heat protector product to your hair, which will help to seal in moisture and reduce the damage that can be caused by using a hot straightening iron.
6. Divide your hair into two layers -- the bottom and top layer of hair -- and clip the top layer to the top of your head so it is out of the way.
7. Use the straightening iron to mold your hair, starting at the hair nearest to your head and gradually moving the straightener down to the tips. Do small sections of hair bit by bit, about three inches wide; this will give you the most even and effective results.
8. Remove the clip holding the top layer of hair and follow the same instructions for this section, too. Use a mirror or ask a friend to help you do the back of your head, which can be hard to see and reach.
9. Apply a shine spray to your hair to give it a glossy finish. You can also use hairspray to hold the style in place for an extended period.
