Flat dreads & Dandruff

I've had them for over a month now and a lot of them are going flat. I know this is normal but I was just wandering if there was anything I could do to help them round again.

Then dandruff! I don't use anything in my hair. I actually have only washed my hair twice. Even before I dreaded them, I stopped using shampoo andconditionerto get my scalp used to it. But damn does it look like I have snow all over my head. Anything I can do about it or just stick it out? Also, I'm broke so I don't really want to be buying any expensive stuff.

Thanks guys!

I have both! What portions do you use? Because as I said, my dreads are new so I'm worried to try anything new.

Thank you so much! I will do that this week!
