what causes gray hairs?
In: Biology
As you get older you produce less melanin which is what causes your hair to be the color it is. Can be affected by many things, aging, stress, and vitamins generally the biggest factors

Lack of D3, B12 are what most people say.
And I’ve read reports that D3 can supposedly reverse grey hair. But take that with a grain of salt.
The pigment balls in your hair is gone, which is also why grey hair is stiffer and rougher.
In Traditional Chinese Medicine, they claim it is due to your Kidneys not working properly.
They use Kidney tonifying herbs to reverse it.
As a side note, technically, there’s no such thing as grey hair. There is only your natural colour, and white.
It just comes across as grey because of the blend of dark and white.
(Hence why blondes don’t ‘go grey’; they get a bit lighter and then have white hair.)
My uncle was grey before 25, I started at 30 after having a kid, and I’m a full silverback at 39.
My GF wants me to color it. I’m changing jobs and am actually considering it. You just don’t want to go from silverback to Jet Black overnight in a workplace lol.
While we’re here. I (28m) have had grey hair since I was 7, it’s hereditary from both sides of my family. I also have very long hair and have noticed random strands not only go from black>grey part of the way through, but also grey>black, black>grey>black, grey>black>grey, etc. what causes the pigmentation to change like that and come back after going grey?
Each strand of hair is a tube, filled with liquid called pigmentation. The thicker the liquid, the darker the color.
The color comes out of little balls in the roots of the hair. Those balls are made by the genes your mom and dad mixed together to make you.
Sometimes, things like how healthy you are or how much of the poisonous stress chemical is in your body (it stays a long time sometimes) can cause the pigmentation to leak out and your hair gets lighter or even white.
And sometimes the genes from your parents decide how much pigment you get to have and when it runs out, your hair turns gray.
100% Children… I’m in my early 40’s with no children and can still pluck the handful I see time to time while most of my peers with children have more than 75% gray/white if they are lucky (the others don’t even have head hair anymore).
