I have brown hair, quite common I guess.

Yeah it is, it is the second most common, after black, which I have.

And what is the least common hair color?
1_Wizard
I would say it is red hair since only 1-2% of the population has it. It's a shame because it is very pretty.

Yes It is.  I guess that is why some people dye their hair red.   Do you know what makes hair a specific color?
