How many laser treatments would I need for permanent hair removal?

Question:
I would like to undergo laser hair removal on my arms. I have pretty thick, coarse hair there. How many treatments would I need for permanent hair removal?

Answer:
The laser is attracted to pigment so the darker, coarser hair is the best hair to treat. Treatments usually consist of 6-10 performed at 6-8 week intervals. Touch-ups may be required to maintain results. I usually recommend 1-2 treatments per year if needed.
