[1] Premature canities may occur alone as an autosomal dominant condition or in association with various autoimmune or premature aging ...

Luckily, recent research has discovered why and how hair starts going gray—and it also may lay the framework for reversing it down the road. Bear in mind that these are early findings, and it ...
The Fischer–Saller scale, named after Eugen Fischer and Karl Saller is used in physical anthropology and medicine to determine the shades of hair color.

A study links graying hair to stem cells getting stuck, unable to color new hair growth. And here's the good news: That might mean gray hair is reversible.
