The first time we see him in the anime with his hair messed up is when they all have the swimming competition

Which makes sense. The water obviously messed up his hair. Next question. 

However, this is how we see him later the same day. His hair is back. Did he have time to style it?? Umm not really so how’d he fix it??

Now, in the hideout-raid arc, he has his hair down as a disguise. But as we know, the rescue squad only spent a few minutes shopping for their disguises, so how did he get his hair from spiked to soft in that amount of time? Wouldn’t hair gel be difficult to get out, especially without a brush and or products?

What I’m getting at is: He clearly hardens his hair. 

He changes between styles way too quickly for any use of product to be plausible. Also he has it up almost every day, which is a lot of work to put in just for a cool hairstyle. 

Bonus evidence: 

My doggo, Ezri, who rarely barks and mostly borks.

She’s a German spitz - in the same family as keeshonds and pomeranians. She might be crossed with something else as her freckled coat, non-pointy nose, and personality are not standard for her breed (they’re usually a lot more high energy and excitable - she’s super laid back and chill). She’s a bit less fluffy than breed-standard too, mostly because she’s grown out from her spring/summer trim (not usually necessary/good for her type of coat but she gets terribly itchy otherwise). It also makes her look like a puppy of a large breed:

Ezri’s best friend is Murder Cat, who is a gentle friend to humans and Ezri, but does things to mice that would make Hannibal Lecter go “Isn’t that a bit much?”

I got Murder Cat as a kitten, and she used to try to nurse on everything when she was small. Eventually, she settled on her favourite thing to nurse on, Ezri, who has never had puppies and a little confused at first but eventually went with it. She grew out of it, but they have stayed snuggly buddies ever since.

New Years here is full of fireworks outside and Ezri gets Vry Scared. I usually set her up somewhere with a snuggly spot right by me, and Murder Cat comes and does this all night: 

She goes everywhere with me in my bakfiets (cargo bike) and lets me warm my hands in her fur on cold days.

And her ears disappear if I say her name to get her attention.

ok so great thanks for coming to my TED talk about my dog, good night, drive safe
