Nah I think it sounds like you're doing just fine the way you are. I too had the dreaded in parts and undreaded in parts thing, it sorts itself out. Just keep on at them like you are and you'll be fine!

Theres not much more you can do really, except wait. I think one of the best thing about having dreads is each person's set is unique. Hes doing it right in his world I guess, you sould like you're doing just fine.

i think it depends how long you've HAD your dreads...2 1/2 months is baby dread time^^ How did you get the dreads? I'm assuming you didn't do the rip and tear method [which i find is the best way to make dreads that last, but not everyone would agree] but as for maintaining?
In my first 5 months, i rolled the suckers once a day, i root rubbed twice or three times a week, and i also used dread gel [not wax] to tighten the little suckers. It worked really well for me. I also started washing them on a regular basis after the first 2 months. But I naturally have very coarse hair, so they were already nice and tight. I find once you've reached the "all my dreads are dreads" phase, that washing them is really good kudos on them. Helps your roots, tightens the dreads themselves, washes out any gunk thats been building up in your head...as long as you're using some sort of residue free shampoo.
But ya...2 and a half months if early. Just keep up what you're doing for now. If you're really concerned you're early enough in that you COULD condition them all, get rid of them and start fresh [i mean if you think thats necessary] but it is entirely up to you.

BY the way, I'm Sabine. This is my first post. It was long. Ha....
