Laser hair reduction will permanently remove approximately 75-85% of your hair after 8 or more treatments. The remaining hair after your series is often very light and fine compared to the dark, coarse hair that you may have started with. Because our bodies are covered with millions of dormant hair follicles, over time some of those hair follicles can emerge out of dormancy and begin growing new hair that wasn’t present during your laser treatments. So, you may need to periodically come in for “touch-up” treatments over time.
