In that case, it sounds great.
If you have not touched the hair since your last session 6 months ago, then a lot of the total hair was removed in the first session. You may find you can easily go two months before needing another.
You can go every three weeks to catch the small amount of hair that should appear - these will be short sessions.
If your electrologist is happy working on telogen hairs as well, then if you wait 3 months and see how much hair appears, this will be a good indication of how effective the first clearance was. What one doesn't want is to see almost the initial number of hairs again!
You can still continue to experience induced growth from Laser even up to a year or more after your last session. Hopefully that won't be the case but if you get any surges of growth later, it will be difficult to tell if it's a result of the laser or the electrolysis.
