There are a lot of good reasons to let your hair go gray. No one can keep coloring forever and expect to fool the masses. And after a certain age, colored hair on a wrinkled face, no matter how beautiful the face, just looks garish. Hair color contains harsh chemicals, and decades of these being absorbed into your skin can’t be good for anyone. And finally, maybe by going gray, we embrace who we really are and stop covering up and apologizing for the aging process.
