Let me say first that I love my hair! It looks so much better. Thank you for all the wise, encouraging, and honest supinions. (Suggestions + opinions = supinions.)
When my stylist asked what I wanted to do, I told him I'd been seriously thinking about having him dye my hair brown. I told him that I'd been feeling like I needed to start over because I could see three different levels of color in my hair. The top third was lighter, the middle third was medium, and the bottom third was darker. He said it must have been a while since he pulled my highlights and lowlights all the way down to the tip of my hair, as opposed to only doing the roots that have grown out. So there you go. He did the two lowlights to one highlight trick that a couple of you mentioned and he did it from root to tip.
I'm not sure what my haircolor is now. Light brown? Dark blond? Dirty blond? Maybe Amber and Janelle can help me define it tomorrow at church. Whatever it is, I think it's an improvement.
