My dreads never went through a shrinking stage I think because they locked up so slowly (2 years until they were fully locked up). I guess my hair was growing fast enough to make up for it plus a little. Midwitch your dreads look great. What method did you use to start them? I always thought it would be hard to start with super long hair.
Yes, I think mine might be low on shrinkage as well, as it is locking slowly, with small loops instead of huge ones. I started them with TnR (twist&rip) and then since then nothing, just keeping them clean and healthy :-)
