Hair styling for a complete newbie (w/ pic)?

[Physics Dummy]

First of all I'm completely stupid when it comes to hair styling (ex. I just bought a hair dryer yesterday for the first time) so please use simple language.

I had the same pin-straight (natural) hair since I was like really little so I wanted to get a different hairstyle and I liked Cameron Diaz's hair (at some point) so I went to a really posh salon with my friend to get it done, but the outcome looks only somewhat similar. I understand you can't get EXACTLY the same hairstyle but I think my hair now looks really weird for a 19-year-old college student. -_- It cost me an effing truckload of money, too.

Are there any tips on like, how to blow-dry my hair? Or should I use any styling products? Thanks!

Um to the first person who answered, why would I want to blow dry my hair straight? -_- It cost me a lot of money to make it look like this (sorta wavy).

edit: did you watch the video? it shows when you blow dry it you kind of cruve your brush in the direction you want it to go., i probably showed you the wrong video lol sorry but basically blow dry it and curve like her bangs curve and it'll stay that way.
