I once came across an interview of his where he described her as a “something blonde”. I had to look up something in the dictionary and it referred to genetics related to blondeness, and the word essentially meant “natural” in the context of “natural blonde.”

As I remember, the word had at least one “x” in it. As I remember it, the word was something like: xanthial, or xythilial or some such.

For the life of me I can’t find that interview nor remember the word any more. I’ve googled tons of versions of potential word candidates but nothing comes up. Wikipedia hasn’t been much help either.

If you know some scientific terms for “natural blonde”, please share them.


Xanthotrichous? Merriam Webster defines it as “having blonde or yellow hair”.

If not that then xanthous, a term used in ethnology (which might be obsolete) meaning “of or pertaining to those races of man which have yellowish, red, auburn, or brown hair”, as defined by the GNU version of the Collaborative International Dictionary of English.
