Taming Coarse Hair?

I was wondering if anyone could help me out with a problem i've been having.I have tried to grow my hair long in the past, but it never could work out because my hair was so coarse, wirey and bushy. It was always difficult to manage.


I want to know if anyone has any good products or shampoos or whatever to properly relax my hair. Once the frizz is gone, and my hair becomes soft instead of coarse, I should be good to go.

Since my hair is wavy/curly I want to style similar to Nick Valensi of The Strokes:
