There's no white in Lenore's hair before Theo's death
I can't believe I've never noticed this before. This whole time, I've been assuming it was something she'd had from birth. It seems that it was caused by trauma instead. Specifically Theo's death (or possibly physical head trauma from being knocked down by the tree—either way, same incident), because it looks like there's some white in the funeral flashback.
According to some googling, physical injury can cause damage to the pigment cells and cause the hair there to start growing in white. I'm guessing that's what happened here. There's also anecdotes around about getting white hair patches from emotional trauma, but I don't think there's any scientific proof of those. They might still have provided inspiration for the comic, though.
And the symbolism and stuff, the emotional implications of Lenore carrying a visible reminder of her brother's death even after she herself is dead, god there's something to dig into there but my brain isn't functioning well enough to do it rn
