Dry, crunchy hair :(?

I recently got my hair cut from 3 inches past my shoulders to about shoulder length to try and get my split ends off but my hair is really dry and crunchy at the ends. I got it cut around 2 months ago and I have only used my flat iron twice on the bottom part of my hair and when I put it up in a ponytail it looks really choppy and uneven with chunky sections sticking out near the bottom even though I got it cut one length and I grew out all my layers. Also near the front of my head on my bangs there is some newer hair (around 3 months old) that is bent in a lot of different directions and it's thicker then some of the other strands around it. It just seemed so damaged I cut it off ): what could have caused that? I use Wen every day in the shower and leave it on for a long time but my hair doesn't seem to be getting better :( what should I do? Should I cut more off?
