I have brown hair, the second most common hair color, but I wish I had black hair.
I also have dark hair. What is that you like more about black hair?
I just like black hair because it is the most common of hair colors.
Interesting, is there anything else you can tell me about hair colors?
Red hair is the least common and only occurs in about 2% of the population.
Wow! What about blonde hair?
I am not certain on that statistic, but blonde hair is characterized by low levels of the pigment call eumelanin.
