The part I’d be interested in is knowing the age when it could begin. I’ve had crippling amounts of stress when I was younger. I’ve even experienced quite a bit of stress in the last couple years. I haven’t noticed a bunch of new gray hairs at either time.

I’m wondering if there will ever be any easy to tell differences that will indicate if someone can have gray hair through stress or are immune to this condition. Being put in a stressful condition doesn’t seem sufficient to tell because some people seem to not be affected by this or maybe the stress level isn’t sufficient. How’d to gauge what is stressful enough for one and not for another?
