I had mine cut, but not all at one time. If you do an inch every couple of months, eventually it'll be gone without you losing all your length. Protein might be good as these ladies have mentioned. If it's too much for your hair, you can just put it on the ends only. I use Sally's version of k-pak, and it works really well.
