I'm a male interested in beginning laser hair "reduction." I'm not interested in getting rid of all my hair in some areas (chest and legs), just reduce "half" the thickness. Is it possible to thin out the amount of hair by having only a few treatments, or will the hair come back patchy? One place I went to said yes, but another was concerned about how it would come back and only was familiar with getting rid of all the hair. Thank you very much in advance.
