1) Come in with the texture you hope to wear most often after the change. This is important when going in for cut or color-the stylist has to see how your hair falls most of the time. So if you're going to wear it wavy, come in with your hair wavy. If you blow it out straight all the time, come with it straight.

2) Bring pictures of your *own* hair. Everyone thinks to bring in shots of celebrities showing off the look they're going for, but if you've got any shots of your hair closer to your new length or color, that can give the stylist a preview of any snags that may come up along the way. And if you've got any examples of things you've had happen in the past you don't want to run into again-a mushroom cut or a highlights you thought were too obvious-bring those, too.

3) Ask a lot of questions about how the styling and maintenance will be different for your new look. It's easy to get caught up in the final unveiling and forget to think ahead to having to deal with your hair on your own the next day. So start interviewing. Will you need a lighter weight product with your shorter hair? Are there things certain ingredients that will help keep your color bright? Will your new bangs need a certain kind of brush to blow out? Just keep asking. It'll make the adjustment period a lot less painful.
