Visible crew/equipment: In the scene where the Sioux discover the rotting dead buffalo lying in the valley, as they are riding by them, right after they show a Sioux woman crying, in the background you can see a man with dark hair in a white shirt lying on the ground. In the special edition DVD, if you watch this scene with the commentary on you will hear Kevin Costner and Jim Wilson admit that it is an assistant cameraman trying to get out of the scene.

Dances with Wolves (1990)
1 visible crew/equipment mistake - chronological order
Directed by: Kevin Costner
Starring: Kevin Costner, Mary McDonnell, Graham Greene, Rodney A. Grant
Revealing mistake: In the extended version of the film during the buffalo hunt, there is a shot of a buffalo making a turn and in the distant horizon, you can briefly see a modern radio tower on top of a hill.
John Dunbar: The strangeness of this life cannot be measured: in trying to produce my own death, I was elevated to the status of a living hero.
Trivia: Kevin Costner had a nasty fall from his horse during the buffalo hunt scene, and everyone freaked out, because since he was the director, the star, and the producer, production would have shut down. Fortunately, he was fine.
Answer: He shaved it as he began spending more time with the Lakota. Native American tribes rarely accepted facial hair. As you can see, none of the other Lakota men have any. He also grew his hair longer as an abandonment of his military lifestyle.
