What styling product?

What styling product would be best for my hair.  Ive got rather thin hair and looking for something that is light so it wont weigh my hair down after a few hours or being in a busy place (moisture) but also something that will hold my hair in postion for a considerable amount of time.  Is there a product like this that exsists?  My hair is about this length and in this style:

Thanks

Wax

get the kind that comes in a stick like brylcream wax stick or redken wax stick. this kind of wax have a very high hold factor but it doesnt make hair hard like gel. these kind are also humidity proof. i used the brylcream stick and it was the longest lasting wax i ever used. it lasted 24 hours for me. even after i take my shower the wax still sticks to my hair. its good if you want something that last all day but bad for those who likes their hair free of product by the time they go to sleep (like me), if you are like me then find a low hold wax that is combined with gel, that is easy to wash off.
