Let us examine the ridiculousness of this statement.
First off, for gray to be over it would mean that at some point it would have had to have been in. We don't remember gray hair being socially popular for a very long time! In fact, ever?
Since all hair follicles are on a journey towards gray, it's hard to say that gray will EVER be over. In fact, it's safe to say that colored hair will at some point be over, but never gray!
