Will my stylist be insulted if I bring in a photo of what I want?
So you want to look like Brad Pitt. Is this Legends of The Fall Brad, Pre-Angelina Brad, or Six kids later Brad? Celebrities change hair styles as often as they change girlfriends (or wives for that matter).
Your stylist will be better at obtaining the exact style if you bring a picture of the haircut you are trying to replicate. So cut a picture out, pull one up on your phone, or bring in a magazine. From one picture alone we can tell how long it is, what tool was used to cut it, and which product will work best for it.
