Before meeting with your stylist/makeup artist have some general details planned out.
How many people in your wedding party will be needing their hair and makeup done? Don't forget to ask: Bridesmaids, Mother of the Bride/Groom, Flower Girl, other close relatives who may be involved in your big day.
Do you want your hair/makeup done at the salon or at your house? When deciding, consider talking to your photographer if you want them to be a part of the "getting ready experience".
If you want your hair/makeup done at the salon, would you like food arranged for you or do you want to bring something in? It's important to be eating during this time!
What time do you need to leave the salon or your location by? You may need to consider drive/traffic time, photos, getting into your gown, having a few relaxing moments before the ceremony.
