How do I get decent hair?

Dude, I used to have crappy hair, but mine changed a lot through puberty, plus I kind of trained it in a way. I've had a Justin Bieber look for a long time now, it took like 6 years- and then he stole if xD Haha But have you started with the basics yet? Shampoo AND conditioner? I used to use American Crew, and now switched to Paul Mitchell tea tree shampoo and conditioner. It's pretty awesome-both are great and I'd reccoment them. But I can guarantee there are no easy fixes, you have to work at it. I would suggest NEVER to use a hair dryer, that makes it puffy and giant. After washing it in the shower, just towel dry it really well to the point where it's a little damp-and then just let it air dry. Before if dries, I kind of flip it how I like (similar to Bieber) and then just let it dry like that and it stays. I dont know how yours really looks or acts, but that's how I accomplish it- no gel or anything added required. Also, I learned from the chick that cuts my hair that if you wash your hair out with cold water after using conditioner, it makes it shiny. Something about closing hair follicles? But yeah, be patient with it and work with it over time.
