Products to help make straight hair more wavy/ curly?

Hi I have straight hair an it is usually kinda thick but I recently had a hair cut and its a bit more layered etc... But I really want like wavy beach style hair etc and I was just wondering if anyone has any advice on good products I could use to help me achieve this?? Like curl enhancers??? Or do those only work on naturally curly hair??? Anyway thank you!!! :) ps I am not a morning person, I only have enough time o blow dry my hair.... Curling I find to be somewhat of a lost cause.... Especially as my hair either drops curl of just puffs up... Thanks!! :)
