I color my hair at home, too, Char. There's no way I could afford to have it done in a salon. I just did mine yesterday and it killed my arms. I had to keep starting and stopping. But I can get away with doing it about once every 8 weeks. I use a color so close to my own natural color that I don't get the roots too bad. I do it for the shine and the body it gives my hair.
Now...if I could just figure out how to
cut my own hair without causing too much damage I'd be set!!
