I package mine and sell it to the local factory that makes afghans. Grey is supposed to be very hot this spring!
But seriously, my hair used to be a medium-dark brown with reddish blonde highlights depending on the season.
Now it's a mousy, grey streaked brown so I get blonde highlights done every twelve weeks. They pull them through the cap, lighten them, and that's it! I don't have a lot of chemicals coming in contact with my scalp that way either.
