June 11 Retightening: 18 months -- should I color?

You know, my hair just feels...HUGE. I mean, it's HOT outside and I've got mounds of hair for days. So, the photos above give you an idea of how much there is, how thick it is, and how long it is. That's my day look. When I get home from work and on the weekend, I'm sportin' the look below. It's just too hot, y'all!

The biggest thing on my mind right now is color. I've got the "I'm over 40 and grey hairs are poking through my dark brown hair" drama. I saw BlaqKofi's blog and she recommended Naturtint.  My hair hasn't completely locked so I really should sit tight, but I'm ancy. I've thought about that spray color stuff, but then my sister says it rubs off on your pillow at night. YUCK!
