The BEFORE shot of Jo and Beth:
Amy had NEVER had a haircut. This was her first. She wouldn't hold still for an after shot, and her hair doesn't look all that different. She had about 3 1/2 inches cut off the length (it was LONG) and had it angled around her face a bit.
Jo wanted bangs again (much to my dismay, since I just keep thinking that will mean another year of hair hell when she decides she wants to let them grow again) and a shoulder-length bob.
And the big, huge, MASSIVE change - Beth wanted a pixie cut.
