Question

without any sarcastic answers.
why do some men get gray hairs when theres no stress involved and old age is not a problem?
is it genetic?

Answer 1

It is mainly genetic. The hair follicles stop producing melanin (which is what colours your hair - even blondes) and the hair grows out colourless - in other words, white or grey.

There are other things besides genetics and ageing which can stop the production of melanin but nobody ever went white overnight (or, at least, not without the help of bleach) because the hair is only 'alive' at the growing point in the follicle, so it takes some time for a single hair to grow long enough to be grey/white through its whole length.

Answer 2

Where did they get the previous color of hair, or that they had hair at all? Something in their genetic code says so. Some people's DNA says grow straight red hair, others have DNA that says grow wavy brown, others have DNA that says grow kinky black. The DNA messages don't just start that process, but they include other parts, like what to do when they age. Sometimes it is a balance of factors. Some have DNA that says over time, stop growing hair on the top of the head while others have DNA that says make lots of testosterone and then if conditions are right change that to dihydrotestosterone, which then signals that hair production on top of the head slow down or stop. If the signals are also still being given to grow hair, then there's a chance by chemically coercing your body to break up the dihydrotestosterone so it stops telling your head hairs to stop growing hair.

I know that I've talked about balding, but now about graying--the same and similar things are at play in hair color too. The body's internal chemistry is really pretty complicated and it has these competing hormonal switches flowing. When the switches give a certain combination, then hair or anything else affected by those chemical keys goes to work according to the DNA plan. Some are preprogrammed for baldness, some are not, and some can be to a moderate or variable degree. Some are preprogrammed for base hair color and some have programming variation that says 'tone it down' as we mature (age). Stresses can change the hormonal balance and send various messages which can include graying hair, but that is only one piece of the puzzle. We all can draw a poker hand with four aces, but we don't always draw a poker hand of four aces. Our body's chemistry is like that a set of cards that our body continually plays throughout our lives. If your set of cards doesn't have gray, let us say, then your body won't grow gray, unless some set of wildcards that represent stress makes up for it. Unlike standard game cards, each of us has a slightly different deck--me, I've been playing without a full one for years.

I went to college with a guy that turned almost totally gray by the time he was a senior-simple genetics. My first gray hair appeared at 25, but didn't have any more until nearly 40. My older brothers still don't have as much gray as I do. My dad had gray hair since his 20's apparently.

Stress has nothing to do with the changing colour of one's hair, if its going to change, it will change regardless, its pure fallacy that stress causes it. Look at your family, parents etc, have they gone grey early...
