I am seriously overdue a haircut (was overdue pre-lockdown). Can someone knowledgeable tell me what to get done so that it looks less...sad? It's wavy and quite frizzy but fine, and as you can see I have a very square face. Up for fairly drastic changes but I hate straightening it so has to be something which looks ok wavy. Quite like Keira Knightley's erstwhile wavy bob look, but can't help feeling that it might just look good on her because she's, well, Keira Knightley. Can anyone help?
