After the announcement of Crisis Core: Final Fantasy 7 - Reunion during yesterday's anniversary stream, fans are adamant that all the weird stuff from the original game remains in the remaster.
For example: Throughout the original Crisis Core, protagonist Zack Fair will receive emails that you can read. A side story lets you join a group called the Silver Elite - a fancy name for what's actually just an in-universe Sephiroth fan club. The group will periodically send you trivia about Sephiroth - including his hair care routine.
Sephiroth apparently uses a whole bottle of shampoo and a whole bottle of conditioner every time he washes his hair. (GamesRadar+ Features Editor Josh West notes that "if Sephiroth uses all-in-one then he deserves everything Cloud does to him.") He follows up with thirteen different kinds of perfume, with scents including rose and vanilla.
I assure you, this is all actual canon. Fans are rediscovering it thanks to a tweet from aitaikimochi with a screenshot of the original letter.
