Laser hair removal is not a one time treatment,it requires many repeat sessions,for one simple reason.Hairs grow in stages and cicles.Full cicle is about 3 month,and there is only a 2 week period when the hair is in the growing/anagen stage.There for only about 7 to 10% of hair follicles can be destroyed every session.For more info feel free to contact me at 305 864 3333 in my Miami or Atlanta clinics.
