this should only take u about 10-15 minutes. depending on how long your hair is.
1. wet or wash hair.
2. tie wet hair into ponytail, and leave the bangs PLUS the hair around your temples/face, loose and free from the ponytail.
3. use a round brush about 1" diameter, and your blowdryer to dry your bangs. to do this, gently turn the brush under your bangs, (like this http://s3.amazonaws.com/ths_assets_production/attachment_resources/attachments/559/original/blowdry_hairstyle_7.jpg) with the blowdryer pointing downward. be gentle. do this until the hair is completely dry.
5. dry the rest of your hair.
6. now your bangs will be dried forward, they will be easier to style. to make them sleek and side swept...... take a regular brush, and just blowdry them to the *opposite* side of the way you want to part them. so, if you wanna wear your bangs to the left, point the dryer to the right and just brush the hair that way as the heat blows on your bangs.
7. turn off the dryer, and comb your bangs into place, as in the pic you showed. spray some hairspray *into your palm* and then gently smooth it onto your bangs.
the key word is *gently* since you want your bangs to look soft and product-free.
8. voila!
