I was just watching a YouTube video 10 Little Known Facts About Human Hair. Not much too it, but it did mention that "Blondes have more estrogen".
Now I am indeed naturally Blonde, of the shade sometimes called "Dirty Blonde", which is a shade that can appear brown in the interior, and which is fairly easily sun-bleached into lighter colors. Is this related to my transnessness ? Who knows?
What is (was) your natural hair color, and how strong would you rate your CD/TG/TS identity?
