Could a nutritional deficiency cause a hair loss similar to MPB?

I think it's really just denial...If it was diet and stress related, then I don't think it would just affect only your hairline. Hair would probably start to fall out from all over and if there is miniaturization then it's pretty much guaranteed MPB. This is what my dermatologist(s) told me...I'm probably in denial as well...The only thing that's giving me hope is that my temples have always been thin ever since I was really young. For now all I can do is wait and watch...Sucks when people go from telling you "wow, you have really thick hair" to "hey, are you going bald?" Ehh, whatever. I'm not nearly as stressed about it as I was before I shaved my head.

I still feel diet and exercise are often used as excuses for things we just dont understand that well. I agree that MPB is not diet really at all, but if we are told hair depends on these nutritients from diet why is there no solid evidence of MPB stopping from diet? It seems diet would have some major impact if hair depends on all these nutrients constantly spouted on websites.
Right now given what we have you almost need to start propecia before you even have any hair problems like when the doctor looks at you and calls you crazy because you have tons of hair still.

Hairloss due to an unhealthy diet or stress will ussually result in sudden hair loss and hair falling out in 'plucks', it wont follow any pattern.

If you have recession or gradual diffuse thinning, it probably wont be anything else but mpb.
