Stress is known to influence blood pressure and other physiological functions, but if it plays any part in graying, its role is not known.
* Observations of individuals with high-pressure jobs, suffering from grief, or enduring tense living situations going gray prematurely have lead to the impression that being under mental stress hastens the process.
* However, this has not actually been established.
* When a person seemingly goes gray "overnight", it is likely to be a false impression given by the scalp disorder alopecia areata, a condition that causes hair loss.
o Hairs are not all affected uniformly. (Look at anyone who is partially gray: Notice that even hairs on the same person's head behave differently; that is, some hairs turn gray, while others do not.)
o Alopecia areata causes the darker, thicker hairs to stop growing and start falling out first. Because of this selective effect on the hair follicles, initially mainly just the gray hairs remain.
What makes hair go gray?
A loss of the stem cells that supply pigment to the hair follicle has been implicated.
* Ordinarily the pheomelanin pigment that gives hair its color is supplied by cells at its root;
* Hair turns gray when the cells start producing less pigment.
The hair loses more and more pigment, eventually becoming completely white. (White hair is completely devoid of pigment.)
* In some individuals the process begins prior to age 30, while others keep their color into their 60s.

Gray hair is typically a result of natural aging. Pigment in the hair shaft comes from special cells at the root (base) of the hair. These cells are genetically programmed to make a certain amount of pigment (melanin) at specific ages. At some point in the aging process, these cells make less and less pigment until the hair has very little pigment. White hair has no pigment, and gray hair has some but not as much as a red, black or brown hair. Not all hairs respond in the same way or at the same time. So the graying process usually is gradual. You can't prevent graying. Some people start graying in their 30s, and some not until their 60s. Genetics likely play a strong role in graying. People rarely go gray overnight. If they do, it's typically due to alopecia areata. This condition causes the thicker, darker hairs to stop growing before it affects the growth of gray hairs — giving the impression of graying overnight. Alopecia areata eventually causes roundish patches of hair loss

Yes it does coz stress effects you hormone generating cycles and disturbs them so it makes your hair grow grey

I guess it can... but there are alot of different kinds of stress. It's not proven. It could also have alot to do with your genes.
