Depends on the treated area

Gregory Turowski, MD, PhD answers: Length of time between laser hair treatments

A few laser practioners I have been to have given me conflicting advice about the length of time I should wait between treatments. Some say 4-5 weeks is the ideal period while others have indicated 7-8 weeks is much better if one is to target a greater proportion of hair in the right growth phase. What is your view on the ideal length of time that one should wait between treatments?

If the laser is done on upper lip, chin or any area on the face it should be spaced out 4-6 weeks apart. For the body areas, it should be repeated every 8-10 weeks. Facial hair grows faster than lower body hair and it should be done more often. In order for the laser to be effective, you should try to keep up with your appointments and follow the technician's recommendations for the length of time between your treatments.
