anime fans: is it possible for humans to grow blue hair?

[MarioThePhenom]

if this actually is a serious question,

it is, and im very curious as to what the answer is

[ManOfMiracles]

So, is it possible to have BLACK hair?

well xeal, if this actually is a serious question, here is a serious answer:

humans hair-colour is made by 2 different kinds of pigments:
Pheomelanin and Eumelanin (both together are called "Melanine".

Pheomelanin is for red + blonde hair. (this pigment is way smaller)
Eumelanin for brown/black hair. (way bigger pigment, thats why asians have such strong hair)

Grey hair is made by small air-bubbles in the shaft of the hair cells instead of pigments, which are missing at this point.

and obviously those pigments can be mixed.

so no, its not possible to have black hair.
