I wanted a change from the first season because I had to wear a lot of curlers every day. It wasn’t fun and it was hard to maintain continuity-wise. My solution, since I couldn’t cut my hair, with that whole fiasco with the WB telling USA Today ""Nobody can cut their hair", was to go in the opposite direction and get longer hair.
I got much longer hair and I started to have repercussions from that. It was too much for my scalp and it was just creating a lot of ickiness and hardship and was not the right thing to do.
So I begged, half way into season two, for them to let me cut my hair. They did and then it was darker and they didn’t like that dark edge for Cordelia. It wasn’t as warm and effervescent as she is usually, so they wanted me to go shorter and blonder. Hence, I’m growing it back out because I think I’m going to go back to season one style. It will just make life a lot easier.
