Nice song pick, I enjoyed that one. I incorporated mine in the comments below.

His dreads are sewn in, at least that would be my guess based on the length. Hair continually sheds and replaces itself. The hair on top of one's head every two to four years. So when you see someone whose hair is down to their butt and says it took them ten years to grow it that long that is true...what isn't is the fact there is no hair that makes it to ten years old. Hair grows on average of one half inch a month and that growth can accelerate a bit more in the summer months, on average it takes a good two feet to reach the buttocks which is approximately four years of growth, so as some hair is shedding at four years others are reaching their max at four years. So those dreads would be holding an abundance of dead hairs that shed over time but couldn't fall naturally....if trapped and stuck out of the dreads it'd take a whole lot of continually applying some grease to hold them all down instead of having them poking out everywhere.
