Image was everything.
In the Capitol, if you weren't beautiful then you were nothing.
That's why each Victor had their own stylist and prep team to make sure that they would be beautiful no matter how ugly they were in real life, after all, President Snow would never let his precious Victors appear ugly in front of all of Panem.
Finnick Odair always thought that time with his stylist was the biggest waste of his life ever. He had already been blessed with devilishly handsome good looks, so he didn't see the point in spending hour after hour slathering makeup onto him when there was no need.
Th only thing that he did enjoy about time with his stylist was, oddly enough, having his hair done.
He always remembered when he was small he would never get to sleep because he was afraid he would ruin his hair or complexion, even as a small child he had always cared about how he looked. His mother however always promised him that no matter how messed up his hair would get, he would always be able to brush it straight again. True to her promise, whenever he would wake up his mother would always brush his hair for him each and every morning. He could still remember the feeling of the green brush adorned with decorative starfish being pulled through his hair untangling his bronze locks.
So whenever it was time for Finnick's hair to be done he would never complain, he would just close his eyes and remember the morning when his mother would brush his hair with the green hairbrush.
