Know How to Hire
Before you hire a stylist you need to decide a few things: Do you want her to come to you on your wedding day or would you rather go to the salon? Will she only do your hair or the bridal party's as well? Do you want her to come and stay with you throughout the day to do touch-ups before the photo session and the ceremony? Discuss these options with your stylist. Of course, how long you hire a professional to stay with you depend on your budget and her time limitations.
Once you've made the decision to hire, hand over a deposit to save the date, and request a receipt. Another option is to have the stylist sign a formal contract, detailing everything you expect on the big day. It may seem overly obsessive, but this is not an ordinary hair appointment, so formalize the agreement -- it's totally reasonable to want to.
Clock It
Ensuring a great hair day on your wedding day will all come down to timing -- which means you'll need to schedule your hair appointment at precisely the right moment. Do it too early and your coif could start to look stale just as the festivities are getting started, but if you start hair styling too late you'll feel rushed. During your hair trial run, time how long it takes to get your mane perfect, then allow that amount of time plus a half an hour of leeway, and schedule your hair appointment for as late as possible. For example, if photos are scheduled to begin at 4 p.m., and your hair takes an hour, schedule it for 2:30 p.m.
