1. First, wash and blow-dry your hair. Tailor your shampoo and conditioning products to your hair type. For thick, frizzy hair, use a smoothing shampoo and conditioner. For thin, flat hair, use volumizing products.
Dry the roots of your hair with the hair dryer first, then work through the lengths of your hair.
Turn your head upside down while drying to add more volume.
Use a paddle brush to work through.
2. Apply a heat protection spray over dry hair, holding the can about six inches away from your head.
Don’t apply the heat protection spray to your roots because they will look greasy.
3. Start by dividing your hair into three layers. Create the first layer by taking the front sections of your hair and scooping them back with your thumbs to grab all of the hair on the crown of your head. Separate this layer by twisting it and securing it with a hair tie or butterfly clip.
Create the second layer by scooping up the hair that remains above your ears and securing with a hair tie or clip.
The third layer consists of any hair which remains unclipped, which should be the hair at the back of your head, growing around the nape of your neck.
If you have very thick hair, you can divide your hair into extra layers. If you have very thin or fine hair, you may not need to divide hair at all, or you can just split it into two sections.
4.Set your straightening iron to the correct temperature for your hair type. The temperature your straightener should be set to will depend on your hair type:
Fine or damaged hair should use a temperature of between 200 and 300 °F (93-149 °C).
Hair of average thickness which is in pretty good condition should use a temperature of between 300 and 350 °F (149-177 °C).
Very thick or coarse, frizzy hair should use a temperature of 350 to 400 °F (177-205°C).
5. Use the right size strands. For best results, straighten your hair in strands that are 1 to 2 inches (2.5 to 5.1 cm) wide and no more than half an inch thick. If you use sections that are much bigger, your hair won’t straighten properly, but if you use smaller sections, it will take too long.
Hold the hair taut. Use one hand to hold the section of hair taut as you clamp the straightening iron around it and smooth it through the hair. If it’s not completely straight the first time, don’t worry, just pull the straightener through again.
Begin straightening about an inch away from the roots. This will leave a little volume in your hair and make sure it doesn’t look too flat.
