Why your beard hair is a different color than your head hair, according to science
As it turns out, you have different types of hair that grow during different phases of your life - and they can come in different colors and textures.
Deep inside the hair follicles (tiny pockets in your skin that house each strand of your hair), there are two different types of pigment that give your lovely locks their hue.
These two types of pigment are eumelanin, which colors hair black or brown, and pheomelanin, which colors hair blonde or red. Despite what you may have heard, all humans have a little bit of pheomelanin in our hair. It's just that in people with dark brown or black hair, the pheomelanin is effectively masked by the darker eumelanin. If your brown hair has a few golden or auburn tones, that's the eumelanin peeking through!
So what about texture? The hair on your beard - or on your genitals or on your tummy - can be wiry and curly - even while the stuff on your head is smooth and straight. There's another reason for this. As opposed to the hair on your head ("head hair"), the stuff coming out of your beard belongs to a type of hair called androgenic hair, which sprouts during and after puberty thanks to changes in the levels of a certain type of hormone called androgens.
Androgenic hair also differs slightly from head hair in terms of how it grows. Like head hair, it goes through three different growth phases in which the hair grows at different speeds, but these phases happen at slightly different times, which influences how long or short your hair gets.
So there you have it! If you have curly hair in one place and straight hair in another, embrace it. It's perfectly natural.
