What causes a brassy hair color?

Answer by  ccoyne (122)

Brassy hair color is caused by the many contaminants we find in our air. Such as pollution, dust and pollen. To fight the brass you should get a professional quality shampoo that contains ash. Most that are specifically for blonde hair do.

When it turns brassy after a few months, the usual culprit is too much sun and/or too much chlorine. Your shampoo can also be a contributer. Always use a violet based (when dying shades of blond) or "for color treated hair" shampoo to ensure the color stays true and doesn't turn brassy later.

There can be a couple of causes. If you have well water or any hard water (with a lot of minerals in it) that can cause the hair color to change and turn brassy. Also extended time in the sun or in any chemically altered water can lead to the change.

It could be the water you shower with or your using the wrong shampoo. Try a "blue" shampoo, it will keep your blond nice and bright. Your local salon should be able to reccomend a good brand.

Chemicals such as chlorine can do this - do you swim perhaps? Use a shampoo specially formulated to keep blonde hair blonde. Try rinsing it with lemon juice after washing.

Brassy and harsh hair color can be caused by elements absorbed from the environment that alter the color, but most often this is caused by sun damage. Use sunscreen.

It could be the type of hair color that you had put on your hair. Sometimes the colors can fade and change. That is not uncommon, but it is more than likely something to do with your water. They chemicals in the water are probably causing the color of the dye to change. Iron in your water will do this.
