How To Straighten:

1. Blow-dry your hair completely (having wet or damp hair while using this type of heated iron is damaging and ineffective).
2. Plug in your flat iron and select your desired temperature setting.
3. Separate the top half of your hair into a bun so you have less hair to work with at a time.
4. Hold a small section of the bottom half of your hair taut (approximately 1" x 1" thick).
5. Starting as close to your head as possible (without burning it), clamp your  Iron onto the small section of hair you've separated.
6. Pull the iron down in one fluid motion.Repeat steps 5 and 6 until the bottom half of your hair is straight. When finished, take the top half of your hair out of its bun and repeat the straightening process. 
 

How To Curl:

1. Blow-dry your hair completely (having wet or damp hair while using this type of heated iron is damaging and ineffective).
2. Plug in your flat iron and select your desired temperature setting.
3. Separate the top half of your hair into a bun so you have less hair to work with at a time.
4. Hold a small section of the bottom half of your hair taut (approximately 1" x 1" thick)
5. Note: the size of the section you separate affects the size and crispness of the curl. Smaller sections will give you tighter curls, while larger sections will result in big, loose curls.
6. Starting as close to your scalp as possible (without burning it), clamp your straightener onto the small section of hair you've separated. Depending on which direction you'd like your hair to curl, turn the straightener either inwards or outwards a half-turn (which should create a U-shape with the remaining hair and the iron).
7. Maintaining this half-turned position of the iron, pull down the straightener in one fluid motion.
8. Repeat steps 6 and 7 until the bottom half of your hair is straight. When finished, take the top half of your hair out of its bun and repeat the curling process. 
9. When finished, remember to unplug your straightener and store away properly.
