Which kind of hair styling product is for me?

[Euan]

If I want to get my hair like this: http://gerardbutlergals.com/forums/tars/mens-haircuts-medium-length-i17.jpg
what kind of hair styling product should I use, Cream, wax, gel, mousse etc and do I need to straighten my hair before hand?
My hair is similar in length but looks a bit thicker that the picture.
Thanks in advance

You don't need to straighten it. Just blow dry or maybe flat iron it to make it look awesome and messy. Put a hair wax to style it the way you want, because a hair dryer and a flat iron just makes wavy a littlez
