What should I expect when I start my dreads with long hair?

Neglect
You will have results in about two months, they may be good, and they may be bad, you never know when using the neglect method. You will loose a lot of your length.

There are a list of salons with web pages in the links section there is also a list of salons in the methods section.

The Neglect Method is a do it yourself method.

Ok to go get my dreads done professionally?
It is OK to have your dreads made in a salon, many people will say that they are fake dreads, but I do not believe this. I believe that if there were fake dreads are made by using dread perms and bleaches, because the dreads are not matting by themselves, they have had chemicals put on them, to damage the hair so it will mat easier. Let me just say that even though I believe this, I have nothing against dread perm dreadlocks. Your dreads are your own thing, you have the right to make them however you want, and anyone who scolds you about it is just bitter because they made their dreads by doing nothing to their hair because they didn't do any research to find other methods of doing it, and they're upset because they have been working on these dreads for about 6 years and they still look like crap and you just walked out of the salon and your dreads look awesome.

Salons usually charge between $100 & $400 to make dreads. IMPORTANT! Many salons say that they do know how to make dreadlocks, but few really do. They will just put your hair in twist and cover it with gel and call them dreads and charge you $200. The best thing to do is decide which method you would like to start your dreads with, print it, and call around. Just take the directions to the salon and tell them THIS IS HOW I WANT THEM DONE! and see if they can do it. If not, try another salon, you will be able to find one that can make the dreads the way you want them.
