You guys seem to know a lot about hair, and i have had this problem for quite a while. I am trying to grow the flow (Long Hair with lots of waves and slight curls)
The problem is, i have pin straight hair that kind of looks like this.

I am trying to get this look below, with long shoulder length hair that is very volumized and wavy.

something like this ^ or this below

i really like this guys hair ^ because that is exactly the way i want it to be.
I have gotten a few tips from people like braiding my hair when it is wet or try using a straightner to create waves. But i'm not sure that would help considering my hair is pin straight.
