Character development is Aragorn finally washing his hair at the end of Return of the King
Although! He did wash it in Rivendell, in the first movie.
…although I doubt he wanted to…
Elrond: “Come over here, Estel. I have something to show you”
Aragorn: *walks over*
Elrond: *grabs Aragorn by the neck and shoves him face first into a bird bath*
