NO! The best part of having Laser done is that once you finally decide to take that step you never have to look at that unsightly hair again! You must avoid bleaching, plucking, threading and waxing hair for 4-8 weeks prior to treatment (depending on the area). The only thing allowed is shaving or cutting. You can also shave in between treatments and this will not affect the Laser or make the hair any stronger. Plucking can cause stimulation of new hair growth in hormonal areas such as the chin & upper lip.
