Loose hairs
Introduce Yourself
Eagle only makes those comments because he know about dreadlocks and he cares about the health of your locks.
You could use a hook to "clean up" those hairs, but you will be breaking tons of hairs in the process which ends up making more broken hairs stick out of the body of your lock which makes them look frizzy. Then you'll crochet those hairs back in which breaks more hairs and so on and so on. Talk to the people in the recovery forum to see what happens to crocheted locks.
You should just leave them be. The 4 month mark is usually the messiest stage. in a month or so you will see those loose sections start to come together really quickly. There's absolutely nothing that you need to do to "fix" them.
If you feel like you really want to coax a section along. Get a bead with a small enough hole and slip in on that tuft of hair. Beads generally help speed up locking. But at 4 months, you don't have to do anything. Like I said, 4 months is a messy stage. but 6 months sees much improvement and pretty much all forward progress. Talk to Valerie. She's a little ahead of you, I believe. She can give you tons of insight into where you'll be going in the next little while. Eagle and I know, but are a little further removed from that early stage
