Here's all the steps you need.
1.Straighten your hair. It isn't too smart to tease it curly or wavy because it damages it easier. DO NOT FORGET TO USE A HEAT PROTECTANT FOR YOUR HAIR. Scene hair gets damaged easily, with all the teasing and straightening. The least you can do is take every precaution to prevent damage as much as possible.
2.Brush hair to make sure all knots are out.
3.Tie back the top layer of your hair, leaving the bottom hanging loose.
4.Using a rattail comb, separate the piece of hair you want to tease. Clip back everything else.
5.Tease the hair. It is just brushing your hair backwards, starting at the end and brushing towards the root. Pass as many times to achieve desired height. Start about halfway up the hair and quickly brush it down to the root.
6.Spray the piece with a firm hold hairspray.
7.Repeat the steps with all hair you want to tease.
8.When you have finished teasing with a comb, it is a good idea to go back through and tease the top layers gently with a brush.
9.When finished, use both hands to smooth back your hair, or, for extra volume, push up the layers of your hair from the roots with your fingers. Fluff your hair my shaking your head a little.
10.Spray all of your hair with hairspray.
