Laser hair removal hollywood fl removes unwanted hair permanently by targeting and damaging the root of the hair. The laser itself is attracted to pigment or colour. Assuming there is a good contrast between the skin and the hair, the laser damages the root and leaves behind a small stem. Over the next 2-3 weeks, it will appear as if the hairs are growing when actually the skin is naturally pushing this stem up and out. If you were to pull at these hairs with your fingers instead of tweezers, 2-3 weeks after the treatment these hairs slide out with no resistance at all.
