If you want them looking good, it's a LOT of work, Palm tolling etc, go on dreadheadhq.com, for products, tips, pictures, everything. I had them for two years, couldn't be arsed to maintain them, they looked shit. For people who think they are 'dirty' they have to be cleaned a lot. Greasy hair doesn't matt, they have to be clean in order to be good dreads basically, it's just that residues from normal shampoos untie them. So look into what shampoo's you can and can't use. (Look on dreadhead) I would personally say don't get them. You just get treated differently and judged, it's not worth it I don't think. At least take your time and think about it. IF you get them, for goodness sake take care of them! Then it's more socially acceptable. Be prepared too hear ' Look it's Bob Marley, haha ' every day that you have dreads, everyone who says it thinks they are funny and don't realise that you have heard it 100's of times.
