How do I make my hair look better?

I have dreads at the moment and I don't use much on that. But is there anything I can do to make them look better? Or my hair in general. Is there any way I can make myself look better?? Right now I use blue magic on it and that's basically it. There was a leave hair conditioner I used but that made my hair fall out. I immediately stopped using but I had done my research before hand and the reviews LOOKED GOOD?? Not only that but l've had a lot of pol telling me they wanted to see what I looked like with out dreads to the point that it got me thinking they look bad. And one of my friends even said they looked like shit and that I should start over. What do I do????????
