This study is a multicenter study. Subjects that completed the basic treatments of previous Hair2Go studies (OHR-2, OHR-3, or OHR-5-Face) will be offered the option to enroll in this study that will not include treatments. The individual data collected in the OHR-2 (and its extensions, i.e. OHR2-P and OHR2-1Y), OHR-3, and OHR-5-Face studies will be used for the analysis together with data gathered in this study. Photographs of the previously treated areas will be taken 3, 6, 9, and 12 months after the last basic treatment if they were not already taken as part of the OHR-2, one of its extensions (i.e. OHR2-P and OHR2-1Y), or OHR-5-Face.
