You'll probably notice the outcome straight away post treatment. The results differ between people, and depend on factors such as hair color and thickness, skin color, age, hormonal level, location of the treatment area, and the type of laser used. After each session, the hair will grow less and slower. In general laser eliminates 70-90% of hair permanently.
Removing hair usually requires 10 to 15 laser treatments. Most patients do not see any hair on the treated skin for months or even years after completing the treatments. When the hairs eventually grow back, they tend to be fewer, finer, and lighter in color. And voila! You have a smoother canvas to work with.
