Effects of aging on hair color: Children born with a certain color may find that it gradually darkens as they grow. Many blond, strawberry blond, light brown, or red haired infants experience this. A change in hair color typically occurs naturally as people age, usually turning their hair to gray and then white. More than 40 percent of Americans have some gray hair by age 40, but white hairs can appear as early as childhood. The age at which graying begins seems to be almost entirely based on genetics. Sometimes people are born with gray hair because they inherit the trait genetically. Some people use hair dye to disguise the amount of gray in their hair. Two genes appear to be responsible for the process of graying, Bcl2 and Bcl-w. The change in hair color is caused when melanin ceases to be produced in the hair root and new hairs grow in without pigment. The stem cells at the base of hair follicles are responsible for producing melanocytes, the cells that produce and store pigment in hair and skin. The death of the melanocyte stem cells causes the onset of graying.[4] [edit] Other medical conditions affecting hair color Albinism is a genetic abnormality in which no pigment is found in human hair, eyes or skin. This results in gray, blue, or red eyes. The skin is pale and the hair is white or pale blond. Vitiligo is a patchy loss of hair and skin color that may occur as the result of an auto-immune disease. Malnutrition is also known to cause hair to become lighter, thinner, and more brittle. Dark hair may thus turn reddish or blondish due to the decreased production of melanin. The condition is reversible with proper nutrition. Werner syndrome and pernicious anemia can also cause premature graying. A recent study demonstrated that people 50-70 years of age with dark eyebrows but gray hair are significantly more likely to have type II diabetes than those with both gray eyebrows and hair.[5] [edit] Artificial factors affecting hair color A 1996 British Medical Journal study conducted by J.G. Mosley, MD found that tobacco smoking may cause premature graying. Smokers were found to be four times more likely to begin graying prematurely, compared to nonsmokers in the study.[6] Gray hair may temporarily darken after inflammatory processes, after electron-beam-induced alopecia, and after some chemotherapy regimens. Much remains to be learned about the physiology of human graying.[7]

I think T-Bone's answer relates more to greying and other hair conditions. I have experienced the same as you, and think it has more to do with lifestyle, or at least in my case. As a child, I spent A LOT of time outside in the sun - during break-time, all afternoon, all weekend. I was also in the swimming pool in the sun most of the time. As an adult, I spend less and less time outside in the sun. I find that my hair tends to lighten a lot when I spend a lot of time in the sun (bleached by the sun), but unfortunately I don't get much time in the sun, since I'm always in the office, in the car, etc.

Stop fighting it .. you will soon be grey .. I know . then you can save money on highlights .. Face it grey almost looks blonde ..

havent got that problem , I seem to grow through mine the older I get

69 mths ago

I actually thought exactly the same thing as Catz - I spent more time outside when I was a child and nowadays when I do spend time outside it does bleach again, but I don't get to play outside that often anymore. :)

I Catz is quiet correct I noticed over the years how one of my family members turn brown from being extremely blonde due the fact that they do not spend time outside.

If you tend to have fair hair, that would be true - especially since kids spend more time outdoors, swimming, etc (the chlorine in pools also bleaches hair). But dark haired people don't experience that - well, I haven't anyway! :-)

mine gets grey the older I get

As children, human like to play alot outside in the sun. The sun "bleaches" your hair. As you get older, more homework, etc. you get less explotion to sunlight. Then your hair gets darker.

Soon as you put some sort of chemical in your hair it grows out darker. The sun also effects blond hair. The chemicals that are put in our shampoo's and conditioners also in the long run effect our hair colour.

69 mths ago

It's probably because you don't spend as much time outside in the sun as you did when you were younger. I was blonde as a child, now I have brown hair.

69 mths ago

I think hormonal changes also have effect

69 mths ago

Agree with Catz.

I know this is a bit strange, but I've been told that our hair darkens because of exposure to sunlight. Now, you may say that sunlight bleaches hair and I agree. But what I mean is that the melanocite (which gives your hair and incidentally your skin it colour) produces more melanin when it is exposed to sunlight and so NEW hair (i.e. hair still inside the scalp, hair follicle, whatever) will grow darker. On my baby pictures I was strawberry blond, now my hair is a very dark brown.
