I have blond hair. I wonder what the most common color of hair is?
I'm not sure but it's fascinating that hair color depends on the absence or presence of a pigment eumelanin!
So the pigment eulelain is what determines hair color?
That's right! And now that I think about it I remember it was black hair that was the most common hair color, brown is the second most common.
Is it an excess of eulelain that determines the depth or darkness of hair color?
Yeah, in general the more eumelanin the darker hair color, the less eumelanin the lighter hair. Pretty much like skin depends on melanin.
So, there must be an abundance of eulelain in the atmosphere with so many people walking around with black hair! lol
Yeah apparently! The darker natural hair colo the more individual hair follicles too!
So darker haired people hair thicker hair as well?
Yes that appears to be true. Unfortunately some people suffer from pattern hair loss and can lose their hair in patches.
