Hair changing colors in shaded worlds

[EnaWaa]

Hello, I have an issue where the hair on my avatar, which is supposed to be white, will change to whatever color is used in the current world's lighting.
This results in the hair becoming purple, blue, green, etc if the hair is any light color. If the hair is black, it's mostly fine.
The rest of the avatar appears perfectly fine, it's just the hair having issues despite both using liltoon.

How can I fix this?
