Why does my beard grow so many different colors?!

It's genetic. That just happens to some people. Hair color is not determined by one gene but instead by a whole range of genes that interact with one another. It means that you probably have genes for all those different colors, it's just that "brown" won out on most of the rest of your body.

Some guys get big patches in their beards that are different colors. Some guys get stripes. It's kind of cool. :)

You'll actually find that the hair on your head isn't one uniform color either, but it's often a closer range of shades than your beard might be. The hair on your temples is probably a lighter shade than the hair at the back of your neck. That's a pretty normal growth pattern.

Genetics, personally, I think it sounds pretty badass.

Who know. But it's the way God made u personoly I think that's kinda cool
