My dreads won't dread

[togam]

I've tried wax (which I washed out with very hot water and dish soap), salt water spray and dread dust. I've tried crocheting, palm rolling I've tried just doing nothing for a year but applying some salt water spray and some dread dust 2-3 times a week. What happens is that they undread, I get more and more loose hair, they get thinner, there's serious weak spots and a few have fallen off.
It's been 3 years since I got them.
What do I do?

How did you start the dreads?
