well i will say they dont look too bad tbh...for what looks like braids (though its hard to make out from the pics) ok dont use wax, it really does hinder knotting as it stops hair from moving freely and knotting and feels horrid after you have slept on it. chuck that fudge spray or give it to some pretentious wannabe high street model...fudge is some stupidly expensive styling crap and NOT needed for dreads. now i can imagine it sucks to be told you dont have what you wanted after traveling all the way to london. you could leave them in and as they unravel / frizz out you can crotchet them back in and eventually they may look more like dreadsthen braids or you could do it the long way and unravel them all and back comb the sections, they wont look as neat like they do now (not by a LONG shot) but they will be dreads. whatever you do keep the sections you got, they will be some wicked fat dreads when there mature. kinda wish i did my sections that big, now im stuck with about 60 dreads that i dare not comb out for fear of my girlfriend. oh btw dont worry about them unraveling or having and inch + of undreaded hair at the tips...thats just the nature of dreads.
eeww wax is bad bad bad if you want dreads get rid of your comb by some natural residue free soap like dr bronners then just wash ur hair every 2-3 days or more and dreads will come if you want your dreads to come faster than that back comb them and then wait oh also if ur hair is dry don't use wax use aloe vera on your scalp and hair
