I have had my dreads for more than a year now. I used Dreadhead HQ products.

A friend of mine did them....It took us a whole weekend 5pm-2am each day. Now I am not saying that it will be the same for you. I had chin length hair too.

*Oh and when backcombing the roots in the beginning.....watch out I found it very painful*

Now a good friend got hers done professionally. They permed her hair first and skipped out on doing the roots. It took them 6 hours for her and she had chest length.

I have over 40 dreads while my friend has about 25....
