Does your hair change when it turns GREY?
Science of Grays As you age, these cells start to die. Without pigment, new hair strands grow in lighter and take on various shades of gray, silver, and eventually white. Once a follicle stops making melanin, it won’t make colored strands again.

When does your hair start to turn gray?
If a single strand of hair starts out brown (or red or black or blond), it is never going to turn gray. Your hair follicles produce less color as they age, so when hair goes through its natural cycle of dying and being regenerated, it’s more likely to grow in as gray beginning after age 35. Genetics can play a role in when this starts.
Where does gray hair start at the root?
Gray hair starts deep inside the hair root with special cells called melanocytes, which your hair relies on for color. There are two components that make up hair. Keratin is a protein that gives hair its structure, while melanin gives it a specific hue, says the Library of Congress’ Everyday Mysteries website.
Is there a gene that causes your hair to turn gray?
In a study published in Nature Communications, researchers even found the primary gene involved with premature greying—IRF4. This gene is in charge of regulating and producing melanin. When your body starts producing less melanin, it causes your hair to turn gray.
What’s the difference between gray hair and white hair?

What causes hair to go gray?

How fast does grey hair grow?
Eventually, if all the pigment cells die, the hair grows in completely gray. The graying of a full head of hair typically occurs over a long period of time. From the time a person notices the first gray hair strands, it can take 10 years or more to complete the process.
