Had the first kid and got quite fast lot's of grey hairs. I was really stressed with having enough time to do my work properly and to handle the daycare deliveries/pickups. The kid got older and needed less of my constant attention, and greying stopped for several years.

Then had the second kid and entered again into this constant not having enough time for anything mode. In the last 2 years I've been getting tons of grey hair, again. This time while I am much older, I can cope with the stress and constant tiredness even worse.

So I am a firm believer of the theory.
