This was before a spring chorus concert. While we were waiting for our epic instructor, we were just talking

Kat: Okay so, if you dyed all your hair—

Lucy: It would die! :D

All three of us: xDDD

Kat: But seriously, what if you dyed all your hair blue, and it stayed like that forev—

Lucy: It would grow back its normal color

Kat: LET'S PRETEND IT WOULDN'T. THINK LOGICALLY

Lucy: I AM thinking logically!

Me: Think KAT Logically

Kat: If you dyed your hair baby blue and it stayed like that, and then your baby has blue hair

Me: Yeah 'cause it's baby blue o3o

Kat: Yeah but think about it. If you dye your hair blue and then your baby's hair is blue...

Me: *thinks about it*... I'm pretty sure this is how anime hair came to be

Kat: See? SHE supports my theory

Me: A HAIR THEORY. >:D
