I tweezed a few hairs 1 day after laser hair removal

Hello, thank you for you question. No worries, you will be coming back probably at least 6 times and those follicles that you tweezed will eventually get back into the "growth cycle". 

Hello, and thanks for your question. The reason why you don’t want to pluck or wax the hair that is being treated with laser hair removal is that these methods completely remove the hair from the follicle, leaving nothing for the laser to target. Thus, you’ll need to wait for the hair to grow back in for the treatment to be effective on that particular hair. Since laser hair removal requires multiple treatment sessions and you’ve only plucked a few hairs, you shouldn’t have anything to worry about. Moving forward, just make sure you don’t pluck or wax your hair. You  can shave, though. 

The hairs you tweezed would not have been in the growth phase for your first treatment and therefore could not have been affected by the treatment.  However, by the time you go back they may be back into the growth phase and affected.  Generally, it takes 5-7 treatments to get all the hair removed in one area.  It takes this many treatments because hair is only affected by the laser if it is in the growth phase during treatment.  It is very unlikely to get every hair in one of two treatments.
