The e3000 place gives as a prerequisite to their electrolysis that you have not had laser for 3 months prior. I wonder why they say that? I haven't talked to an electrolygist yet, but plan to.
A reason I can imagine is that if you appear to have much sparser hair in an area after laser treatement, then get electrolysis, then hair grows back, it would be unclear if it is the electrolysis or the laser that didn't get all of the hair.
If there is a planned iteration of treatments, it would be slightly messed up by not having a good guess about what state of hair regrowth cycle you are in in the area that was treated with both.
I am guessing. At least, that means that if you plan to go there in particular, know that you would need to wait 3 months after laser.
