East Asia girl with brown hair boy with brown hair The natural hair color of
East Asians is mostly brown to black. Regarding natural brown hair, Darkest brown and Dark brown to Reddish brown are the most common, and sometimes Darkest brown is mistaken for black. Medium brown hair is also quite frequent, and while light brown hair is less common than medium and dark brown, it's still present to some extent, not rare. Even hair that appears visually black can reveal its color when exposed to light if it contains natural reddish-brown pigment (pheomelanin). Like Europeans, East Asians' hair color gradually darkens with age, which is why there are more young people with brown hair.
