I've had vitiligo since I was six, so I started getting white hair in my beard since I was 16. At 35 my beard and eyebrows were completely white. So when I shave my beard off it's like I got 10 years younger. 😂
My vitiligo is also why my first fursona was a snow leopard. I am my spots and my spots are me.
When I wear a beard it's gotten pretty salt and pepper. My hair is also beginning to turn gray in a similar fashion but isn't as far along yet, it's still mostly darker. I'm heading on 50 though, so I guess it's about time.
