Nix08, you and dh say don't cut because of growth pattern.
I haven't had a cut or trim in a while...well, I used my split ender but that really doesn't count though. So, I'm due for a good trim/cut but how much is the wild card.
My hair doesn't grow evenly. The left grows faster than the right, so it seems.
I sleep on my right side. I read that makes a difference. I'm right hand dominate. My right side suffered the matted locks and the length & health of it has not been the same since. I do believe my hemline was healthy before the matting scenario. Previous cuts were done with preserving length in mind. In hindsight, I should have gotten rid of all the whack ends at that point and start truly fresh and new.
