If coloring were more of a pain for me, I'd probably consider stopping--but it really isn't. I use semi-permanent so I don't have a stark line of roots, and it just takes 20 minutes or so every 4-6 weeks (whenever I notice it starting to get particularly dull). Also, I fear instead of beautiful silver I'll just have brown mixed with ugly streaky white. Ah well. If this is the biggest thing I can find to complain about, my life is pretty good. And more importantly: you look marvelous!
