: I've heard a phrase something like, "Her hair turned white overnight" as a by-product of an extreme shock. Are there actual instances of this? I didn't think that was scientifically possible. Where did that phrase or idea come from? Thanks for any info!

Here's what I read somewhere. A person's hair doesn't turn white. But stress can cause rapid hair loss and "reveal" white hair that was already white.
