I think you'll find nearly complete consensus with that statement on these forums. BTW welcome to the forums.
wax will ruin dreads in the long run. no horror stories cause me and my man have been all natural since the beginning of our dreads! I keep saying I'm gonna get some photos up... soon!
I've had lots of clients with beautiful dreads who used wax. I'm a dreadnurse and use crochetinghooks to put loose hairs in. But when I tried to put the crochetinghook in it didn't work at all. The locks were hard like stone :S and when I managed to put it through all kinda waxy dirt came out. Very gross.... but the locks looked great ..
when I first started my dreading journey, I used wax. I didn't know anydifferent and I was going on what everyone else said "use wax". That lasted 2 months. I thought they were starting to knot up really well because they felt really firm, WRONG, that was just the wax. Ew. Oh, and a warning to anyone wanting to get wax out, hot water burns! The amount of times I spent bent over with my dreads in a sink of boiling water is too many to count! Worked wonders though and my dreads are so much better for it.
