Everyone knows the fastest way to update your look is to get a haircut. But do you know how? Answer these three questions as honestly as you can. Keep in mind, though, that if you answer yes to any one of them, you may be suffering from a common condition known as ignoramus clienteles. (Don't worry, it's easily treatable!)

• Did you cry after your last haircut?
• Are you sporting a mullet when all you wanted were long layers?
• Were you wondering why your hairstylist didn't exactly seem delighted to see you?

Welcome, ignoramuses! Don't worry ‑- who hasn't been wronged at least once in the hairstylist's chair? Happily, there's a remedy, and like most things in life, communication is the key. So before you make that next appointment, check out this guide of dos and don'ts, and get ready for the haircut of your dreams!

Don't get your hair cut during a crisis: If your romance just went bust, you got fired or you've had a fight with your best friend, it's probably not the best time for a haircut because your emotions may interfere with your decision-making, and you might go for an "impulse cut" you'll regret later.
