Since June of last year, I've cut 20 inches off my hair. It used to reach that area where my butt turned into my thigh, now it's bra strap length. Talk about a shocker! It was really healthy, but it wasn't very stylish. Now it has a bunch of layers and I had red highlights put in and I love it. Sure, I miss my hair (it was the only thing guys used to comment on when I would go out for a night on the town) but I'm glad I did it.
You'll get used to it. And once you start playing around with it, the shorter length gives you so many options!
