Why so wayang? Just leave it to mother nature and mother nature's good friend, old age!
I used to get my dreadlocks done at a HDB hair saloon for $25 - complete with trimmings, shampoo and the the trying - I only had to bring my beads. ;-)
Great value for the money and if you find a good 'aunty' she'll be so glad to be able to do it for you, cos' she gets to show off to her regular customers. Be prepared for two hours of work - have magazines on the ready and down a Baron's Strong Brew before the episode.
Good Luck and don't forget to spruce up on the talent count - that matters too. ;-)
Cheers
