Dwarves were known for taking care of their hair. They took pride most of all in what they had on their face, but dwarves also took care of the hair on their head. They may not have let it flow free, completely loose and free of any form of braids like many elves did, but they didn't let anything happen to it. Tauriel had only seen two balding dwarves before, and after the battle had ended and Thorin had been declared king, she had met more than a few dwarves.
One of which had been Nori, who was far too much more trouble than he was worth.
"What in Aule's name did you do to my hair?"
"I thought you liked the look." He grinned.
Tauriel looked at herself again in the mirror. He could pull off the strange star look, but Tauriel couldn't do it in her wildest dreams. She smiled back at him. "Have you ever considered what you'd look like with an arrow through your head? I think it would be a good look for you."
