Ninjago Head Canons

Morning

Kai:
As I mentioned in Sleeping he wakes up early so he can get to the bathroom. Kai takes forever in the bathroom he takes a 45-minute shower namely because he's focusing on his hair making sure it's just right, and then he goes off and air-dries his hair.
Styles for about half an hour until it's just right the whole morning process has been times as two and a half hours and five seconds, Jay woke up early and timed him once.

Cole:
When he gets up Kai and Jay have already finished their showers so he goes and takes his, he usually has his own soap because he has a lot of thick hair but every now and then he uses Kai's because it drives Kai crazy.
When he's done with his shower he combs his hair to the side and is done he doesn't like wasting time on his hair like Kai.

Jay:
He wakes up when Kai is at the end of his shower so Jay still has to wait for Kai to finish with his hair, so Jay will play his games while he waits to make sure that he's always in first place.
Once he's in the shower he's done quickly like lightning fast he doesn't like showering because it makes it so that he can't shock people as well afterward.
And once he's done with the shower he just quickly takes a comb over his hair then he's done.

Lloyd:
Showers at night so he doesn't have to in the morning that way he can sleep in later than the rest plus when he goes to bed with his hair wet his hair is really fluffy in the morning so it looks like he styled it.

Zane:
Doesn't shower he doesn't need to so when he powers back on he goes around getting his chores done so that he doesn't have to later when the rest of the ninja do, that way he can play his games and get a higher score than Jay.

Nya:
I imagine Nya to like waking up early. Out of the fear she'll miss out on the hours of the day, she's up and awake getting ready for the day and jumping straight into a project especially while Kai is busy with his morning shower; she'll be up trying to make the most of her day.
