I regret my first laser hair removal on my face.

Don't worry! You may experience some stubble from shaving but it will soon go back it's original growth pattern. Laser hair removal on the face generally takes 6-8 treatments to have a significant reduction in hair growth. After one treatment you will hardly notice any difference. If you do decide to move forward with the treatments, you should start noticing a decrease in the hair growth by around the 3rd treatment. Think of it as a thinning process. Good luck with whatever you decide to do!

Hello, after only one laser hair reduction treatment you shouldn't notice a significant difference in hair reduction.  You may notice stubble growing back after shaving.  This will growth out to normal length and go back to baseline.  There is no need to worry.  
Regards,

Thanks for your question and you will not see that much of a dramatic response with one laser hair removal treatment and if you do nothing further, 99% of the hair in the area will return and you will do just fine.  The one question I would still ask – why don’t you want to continue?
