Blonde hair is hair color that is determined by hair with low levels of the dark pigment eumelanin.
That is fascinating! I have blonde hair! I don't think it is common as brown and black hair though. 
You are correct! Brown hair is the most common hair with black hair coming second. I also have blond hair.
Neat! I wonder if their could ever be any new hair colors that are natural? I know some people dye hair.
I don't know! lol My daughter dyed her hair blue at one point. The darker your natural color the more hair follicles you will have.
Wow! Did you like it? Is it good to have more hair follicles?
I just laughed basically! lol Blue hair is a hair color that isn't natural, obviously, although some animals have blue hair. The more follicles, I would think the thicker the hair.
Right! Yes some birds have blue hair. It is neat to observe them!
Actually, some people are born with a bluish black hair color which basically means their hair is black but has a blue hue underneath. I love blue birds!
Wow! I did not know that! Is that a rarity?
