13歲應該剪咩髮型, 邊間salon/師傅剪得好...

Style is very subjective. The most important thing is you feel comfortable with the look. The best thing to do is be brave and try as many salon as possible, and build up your own experience. Do ask the barbers for advice too, and then see if you really like it. Unless they want to lose customers, how will they be rude to you?
