I had dirty blonde hair (straight and fine) and dyed it red or lighter blonde through out adulthood. A few years ago I wanted to let it go natural, I was about half silver. (I'm 60). I kept it short for a while too. I do love my silver but I think about dying it now and then and im letting it grow out.
Hmm...I think I will get some red dye next time I go to Walmart. ...
