Steps

Wash your hair gently with good quality shampoo&conditioner.
Towel dry it for 15-20 minutes and then blowdry the rest.
Use a large paddled brush on your hair as you dry it with a blow dryer. This makes the hair very straight. Since you want to create as much volume as possible, you should use the cold air setting to dry your roots.
Curl hair with a large-barreled curling iron. Wrap the hair around the curling iron starting from the hair ends and working until you get as close to the roots as possible. Before curling the hair, section off the hair into three parts using hairclips.
Spray the hair with hair spray after curling every piece of hair.
Comb your hair but be careful, comb it untill you get a nice wavy effect.
Plug-in your flat iron. Start straightening your bangs to the right.
With a good quality teasing brush, tease your crown hair to add volume.
