You're asking?? You are in charge of your hair. If you ask for a trim, and your stylist doesn't want to discuss it, she just wants to do "her thang". Tell her nevermind. If you discuss and she wants to argue, or she doesn't want you to have a mirror---tell her nevermind. The most you should cut at one shot is about 1/4. Because 1 trim should not fix every hair mistake you have. That is called a hair CUT.
