Had laser tattoo removal. Is it true that it takes up to 6 weeks to see significant fading?

I had laser tattoo removal 3 days ago with the Medlite c6 q-switched 1064 nm laser. I don't really see much fading yet, however, the doctor that did the procedure told me that it will take 6 weeks to fade the tattoo. Is it true that I will continue to see more fading in the next weeks to come or is what I see today pretty much the finished result until I do another laser session? Thank you so much.
