And so I decided to take matters into my own hands.

I cut off most of the the relaxed ends from the back of my hair. It was fairly difficult, as I was doing it mainly by touch; I did stop short of cutting all of the relaxed hair, although I was very tempted.
I'm not sure of how much of a visual difference it has made, as the ends from the centre and top of my had seem to cover the area that I trimmed. Still, I feel better and that's what matters, right?
