Laser resurfacing would singe or burn the hairs on the surface of the skin if the laser beam touches the hair but does not affect the root of the hair. So the hair loss is temporary and will grow back.
Laser resurfacing is usually done with an erbium or CO2 laser. While they will help improve the texture, fine lines and wrinkles of the skin, it will not help with hair reduction. A different laser will help with that. Good Luck.
