I'd say give it a month or so. By then you should have another 1/2 inch, or so, of new hair. In that time, what is loose should start to mat. If you have 3 inches of straight hair now, if it doesn't mat you'll have around 4 inches. If in a month you still have 3 inches, or even less, then it's taking care of itself. if you have more than 3 inches, and it isn't showing any signs of matting, and is really bugging you, you could get some yarn or hemp or whatnot, and wrap a few of the roots. Or get a few beads and put them closer to your scalp.
I'd give it at least a month and see if there's any progress though, before you do anything to try and help them along. No need to worry about it right now. don't mess with them either. If you keep fingering them and poking at them, they will take longer to tangle and mat themselves.
