i have blonde hair.
[{"role": "system", "content": "Blond (male), blonde (female), or fair hair, is a hair color characterized by low levels of the dark pigment eumelanin. The resultant visible hue depends on various factors, but always has some sort of yellowish color. The color can be from the very pale blond (caused by a patchy, scarce distribution of pigment) to reddish \"strawberry\" blond or golden-brownish (\"sandy\") blond colors (the latter with more eumelanin). On the Fischer\u2013Saller scale, blond color ranges from A (light blond) to O (dark blond). The word \"blond\" is first documented in English in 1481 and derives from Old French \"blund, blont\", meaning \"a colour midway between golden and light chestnut\". It gradually eclipsed the native term \"fair\", of same meaning, from Old English \"f\u00e6\u0121er\", causing \"fair\" later to become a general term for \"light complexioned\". This earlier use of \"fair\" survives in the proper name Fairfax, from Old English \"f\u00e6\u0121er-feahs\" meaning \"blond hair\". The French (and thus also the derived English) word \"blond\" has two possible origins. Some linguists say it comes from Medieval Latin \"blundus\", meaning \"yellow\", from Old Frankish \"blund\" which would relate it to Old English \"blonden-feax\" meaning \"grey-haired\", from \"blondan/blandan\" meaning \"to mix\" (Cf.\n"}, {"role": "user", "content": "I have blond hair. I wonder what the most common color of hair is?"}, {"role": "assistant", "content": "I'm not sure but it's fascinating that hair color depends on the absence or presence of a pigment eumelanin!"}, {"role": "user", "content": "So the pigment eulelain is what determines hair color?"}, {"role": "assistant", "content": "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."}, {"role": "user", "content": "Is it an excess of eulelain that determines the depth or darkness of hair color?"}, {"role": "assistant", "content": "Yeah, in general the more eumelanin the darker hair color, the less eumelanin the lighter hair. Pretty much like skin depends on melanin."}, {"role": "user", "content": "So, there must be an abundance of eulelain in the atmosphere with so many people walking around with black hair! lol"}, {"role": "assistant", "content": "Yeah apparently! The darker natural hair colo the more individual hair follicles too!"}, {"role": "user", "content": "So darker haired people hair thicker hair as well?"}, {"role": "assistant", "content": "Yes that appears to be true. Unfortunately some people suffer from pattern hair loss and can lose their hair in patches."}]
