I used to be SUPER into korn so I tried to be like my idol, Jonathan Davis, and grow dreadlocks. But, much like his, my hair isn't curley it's mostly straight so what I ended up with was dirty matted hair. It was downright unhealthy. I took the advice to "Never brush and wash with bar soap". Well it certainly did something to my hair but you couldn't exactly call them dreadlocks.
Just bad hair.
