It really depends. As the day goes on they tend to get behind, so they don't always start at the appointment time. It also depends on which hairstyle is chosen, some take longer than others. We've done it twice and once it took about 45 minutes and the other time it took closer to an hour and a half. I would allow at least an hour an a half before you schedule something after it, maybe even two hours just to be safe and not feel rushed!
