There aren't any additional fees required to use the Groupon. According to the FAQ, "The number of treatments required to obtain optimal results varies with hair density, hair color, skin types, the area being treated, and your hair growth cycle. The density of your hair and its growth cycle are affected by many things such as your age, ethnic background, hormones, and medications. Laser treatments impair the growth capacity of hair follicles when they are in a growth cycle at the time of treatment. All hair follicles are not active at the same time. Depending upon the growth cycle of the follicles when the treatment is applied, several treatments with a few weeks in between may be required to obtain the desired effect."
