Patients need to be informed that a very good result with laser hair removal (LHR) is when approximately 15% clearance is achieved in each treatment session, and that an excellent final outcome of clearance of 80% or more after 6 treatments is exceptional. So, they should have realistic expectations of the results from each session and the final outcome, and in the end they should never expect 100% clearance. Also, some patients will respond very little,
or not at all, even if all the settings and technique are properly applied; this is most likely due to hormonal conditions or other medical issues. The clinician should consider a checkup after the second treatment to ensure, with photographic verification, that hair clearance is progressing at the same or similar rate as described herein, otherwise the patient might opt out of continued treatments.
