What's the recommended time to wax before laser hair removal?

You should not wax 6 weeks before starting laser hair removal and then do not wax again.  You can shave instead.  The hair needs to be in the follicle for your next laser treatment.  For the face, treatments are usually performed 6 weeks apart, but other areas are treated 8-10 weeks apart.  Remember to avoid the sun before and after your laser treatments.  

Thank you for your question. It is not a good idea to wax before you get a laser treatment. Laser target the pigment in the hair follicle and by pulling out the follicle you have nothing for the laser to go after. If you are getting laser treatments just stick with shaving in between and you will have a much better result.
