The Efficiency of the Hair2Go Device: A Prospective, Open, Label Study With Before-After Design

This study is a multicenter study, designed to determine the efficacy of the Hair2Go hair removal device and to compare the extent of hair removal with and without maintenance treatments. Preferably, two anatomical regions to be treated will be selected including the axilla and either the legs (calves) or forearms. The size of the area treated will be approximately 5x5 cm2. Additional areas including the face can be treated according to the subject's request with the PI's discretion but are not mandatory. Subjects will be provided with the device and will be instructed as to the method of usage. The subjects will be expected to self-administer the treatment at the clinic in a "simulated home environment". The duration of the treatment session is approximately 30-60 minutes. Each of the selected anatomical regions (both left and right sides) will be treated with either low, medium, or high Elōs energy level according to the PI's discretion. However all anatomical regions except for the axilla will be treated with either low or medium elōs energy levels only. Only the axilla will be treated up to an energy of 4J//cm2 A defined area of 5x5 cm2cm2 in the leg will not be treated and will serve as a reference for the temporal changes in hair growth that might be subject to factors, including fluctuations in hormone levels. Both sides (left and right) of the same anatomical region will receive the basic treatments. One side will receive 3 additional maintenance treatments in 4 week intervals ("Maintenance" vs "No maintenance" side) until the end of the experiment. More specifically, the study includes up to 11 visits at the clinic: initial consultation, 7 basic treatments in 1 week intervals followed in one side by 3 maintenance treatments, each 4 weeks apart. Follow ups will be conducted at 4 and 12 weeks after the last basic treatment.
