Hi Doc,
Is there anything (medicine or lifestyle related changes) that can be done to reverse or at least prevent greying of hair?
Does stress or inadequate sleep contribute to or accelerate greying of hair?
I can advise you to get adequate amounts of sleep to be healthy and figure out ways to reduce your stress, but that advice would not necessarily deal with your graying issue. Gray hair may be caused in whole or in part by genetics in your case.
