So I've been wig free and babying my edges for the better part of the Summer. I've upped my wash days to twice a week with a dc on dry hair before I shampoo. I'm still using Xcel21 on my scalp, but only on wash days as part of my prepoo. I've come to accept that my edges will never be long, but they are getting fuller.
I don't have any good news about my crown. I'm still struggling with short, weak hair in the crown towards the back. I have been trimming away at the wispy ends quarterly, so I haven't been able to retain any length this year. The right side of my crown is 1-2 inches shorter than the left.
Overall, my ends appear to be thickening up nicely this year. I think by December I can finally get rid of all the damage and start 2018 with clean ends.
