I started graying in my mid twenties, I am in my late thirties now and my hair is a little over half gray at this point. I would frankly like to do something about it, my wife has been insistent that I don't because she likes it.

The possibility of it being some sort of vitamin deficiency that this raises has me feeling like I should at least get my levels tested. I can't imagine that it is a B12 deficiency however due to how much canned fish I consume. It's become my go to easy lunch since the beginning of COVID.

Full grey here. The amount of comments and compliments I get about my hair is unreal. I never really got any before greying.

I say embrace it.

Be careful with the canned fish, especially canned sardines, as they risk arsenic. Canned tuna and some others can risk mercury. I wouldn't eat canned fish more than once or twice a week. Always make sure to cook them well, otherwise worms are risked. The ocean is used by us as one big garbage dump.
