Did you date any of the girls in the last playthrough before you met the girl If you did her name is June That's the only thing I can think of about the different hairstyles Because June aka your future daughter her hairstyle changes depending on who you date on the Playthrough you meet her Like if you date Sarah It's going to be blue Because you both have blue hair If you date Dr Tiff It's going to be brown If you date Val It's going to be a brunette or whatever her hair color is and so on depending on who you date
