Does your SMP hide the transition between ink and your shaved head?

I have a full cul de sac on the top of my head, which is fully bald up top. I did 2 sessions so far, and even though I know I have 1 more session to go, maybe even 2, I don't know how much it will cover my bald spot. When I go to my bathroom mirror with the lights on, I can see the full bald crown still, even when I applied Zero Shine 2.0.

I know that even someone with a full hair who foil shave it down can see a bald halo under certain lighting, I just want to know if 3 sessions will at least hide the ink and real hair and be able to blend it in uniformly even under lighting. Also, how many of you guys with fully bald head needed 4 sessions?
