Its rare to see a woman in the public eye who doesnt color her grays. So when artist Alexandra Grant a 46-year-old with a mane of naturally silver hair was thrust into the spotlight a month ago when she was photographed holding hands with her longtime collaborator Keanu Reeves , 55, people were intrigued.

And not just because some mistook her for actress Helen Mirren .

Grant posted Wednesday on Instagram about her decision to embrace her gray hair while warning about potentially harmful beauty standards.
