If no to interlocing, then what??
Dreading Methods
I personally would suggest that you put up some photos of your locks so we can see what's going on exactly.
A lot of people here are going the natural route where all you have to do is keep your dreads clean and seperate themto keep them from congoing(getting too big)
I would suggest checking the forums about dreadlock maintenance and take a visit over to SoaringEagle's page. He has had his locks for over 20 years and has a lot of knowledge he can share with you.
