Science isn't sure whether stress helps turn hair gray or not; but if it does play a role, then moms are in a primary risk group, and they have very little time to spend putting the color back in.
A permanent fix for the gray would do wonders for busy moms who wish for a life without roots. (And by permanent, we don't mean six weeks, which really is really more like three.) This could be in the form of a perfectly safe, side-effect-free systemic drug, or maybe some type of anti-gray laser treatment or magic wand. Whichever's easiest.
