Girl gets a haircut. Hair is shorter by 1 cm.
Guy gets a haircut. You don't even need a before picture to know it's the after picture.
The real question is, why do you want a haircut to look similar to what you had before? At all?
To get scammed for your money?
I should clarify what I meant: getting a haircut that doesn't drastically change your hair doesn't make sense to me. I'd not get a haircut in the first place.
