Dye Color on Regrowth Hair Too Dark?

I have used temporary box color for about 15 years trying to match my natural color of ashy light brown and cover grays. I have decided to let the gray come in. So with about 1-2 inches of regrowth, I asked my hairdresser to color it to my natural shade. The intention was that the gray would come in and there would be very little regrowth line, if any. It came out much darker than I had imagined.

I am washing hair daily, instead of every other day which had been my previous routine, with only a slight fading and small touch of gray showing at the temples. With so many years of coloring, I'm wondering if this is really my natural color. The dark hair really makes my face look washed out, and because my brows are very fine and thin, it almost looks like I don't have brows at all. Should I go back and have it lightened somewhat, or just live with the darker color until I see if there is a regrowth line?
