Answer:
Laser hair removal offers a permanent reduction in hair growth. Though the lasers do destroy the hair follicle preventing any future hair from growing, it can be difficult to effectively treat every single hair. Some patients may find that years down the road, some hairs may start to come back. The term "permanent" is avoided mainly because laser hair removal technology has not been around long enough for anyone to witness permanent results. It does offer very effective and long lasting hair removal.
