My eyebrow tattoo removal test spot went darker, should I go through with laser removal?

I have eyebrow tattoo's that I dislike and would like removed. They are about 8 years old and have been touched up almost every year in brown ink. A few months ago I had a test spot done with a dual wavelength Q switch Yag laser. The spot went darker, I would say grey/black. Should I go through with laser tattoo removal? I can imagine that after the first session they will go darker but will they eventually lighten after several treatments? Thank you,
