I'm all in on this. Long platinum color hair is my top fetish. There are a very few out there but even more rare to see them wear it down in public. And folks that age are typically not posting hair stuff on social media. Sarahlabyrinth on YT one exception. Also on IG there are a bunch of 40-somethings with prematurely silver hair who are doing hair posts although none I'm aware of with mega length.
