Hi Alain2,

my hair has never been only one color. There is blond in it, much darker parts and lately even some red. I had some grey hair, I think since I am 25, so I am not concerned with it. But I would never dye my hair as long as it is so long. The chemicals are just too damaging. And if I don't like the color, it would take years to grow out or I would have to color it again.
