Well, how long have you had your dreads? How did you put them in? What condition is your hair in? Basically, we're trying to say that there are so many factors that decide how hard or easy it’ll be to unlock, that we can’t tell you. We can estimate this much: a long time. As in, many hours. You may even want to make it a two-day job. The removal kit isn’t a magic pill for your hair, so you will need to use a fair bit of elbow grease. The more elbows you have working on it, the better & faster!
