I'd ask your laser tech. The only thing I can think of is that it takes some time for the laser to have had its effect, usually a few days. You also need to be shaved for laser and hairy foe electrolysis. I think, and it is just opnion, that most people let the laser do its job and then do electro as it is more expensive, so you want to use it to 'clean' up the left overs.
