I adore dreads, if I had longer hair I'd get them. I think they look best if your hair is long, although they're a huge change and a real commitment, if you're planning on serious dreds (not the DIY kind lol) then you'll either have to shave your head or have a SERIOUS hard time when you want them out/let them grow out..so if you're not totally in love with the idea I wouldn't do it. But I think they're gorgeous on boys and girls and say go for it
