I've been using gel for years now, I always try to find a gel that makes my hair like it doesn't have gel in it. Of course everybody knows that it's styled, but at least my hair still looks like hair (imo). My photo on my profile might make things a bit clearer.
Why do I say this? Cause a lot of gels (and especially waxes) will sometimes make your hair look like you haven't washed in four months. A lot of these gels will make your hair very hard as well, sometimes even to the point that you think you can break it in two. Yes, these are the gels that make your hair stay put in the same position for almost the entire day. It's not worth it. Use a softer, less strong gel that you do in your hair in the morning. Just put it up from one side and stroke it to either left or right (depending on your natural hair line). You'll probably need to put it up during the day a few times with your hand. It's natural, girls dig it.
I sound like an incredible cocky douchebag at this point, but really, don't use the strong stuff and don't try anything overly fancy.
