How Much Time Is Allowed To Lapse Between Each Hair Laser Treatment?

You need to space your treatments to allow enough time for ample re-growth.  If you have no hair, you are not effectively treating the area, since the laser needs the pigment in the hair to treat the follicle.  It sounds like your current treatments are spaced fairly adequately - you can even drag it out longer between visits as your treatments progress.  More importantly, since you said you were traveling during the summer, check with your provider since sun exposure and color on skin will affect how most lasers will respond to your skin. You might need to wait for future treatment if you get too much sun exposure and pigment in your skin changes.   

Many people are not able to commit to an every four or six week interval in between laser hair removal treatments.  Trying to match the treatment with the growing phase of the hair cycle is possibly more academic than clinically required to obtain a satisfactory result in reduction of hair growth. If you have had several sessions and can not return for a few months, you can continue on your return.

Thank you for your question! It depends on the type of laser treatment that you have. I would advise you to wait at least two weeks between treatments. Certainly the skin needs to healed and be near its normal condition before repeating the treatment. Please avoid the sun immediately before and after the treatment. Best of luck!
