I recently had laser on my thighs.  I was told I would need 6 treatments.  I have had 3.  I will probably go back soon but I have gone almost 3 months without a treatment & the hair is just now starting to grow back.  After the first treatment I thought I’d made a huge mistake because I could smell a burning smell from the hair & when I walked it hurt & I had red patches on my legs.  However, that only lasted a couple of days.  I am very happy now.  I have been going to an electrolysis for more than 10 years for my face & lower legs.  It is a very slow process & I finally decided to speed things up.  I wish I’d gone to laser instead of electrolysis for my entire legs because it is so much faster.  I would be reluctant to try laser on my face because it left red patches on my legs which I can’t imagine appearing in public with my face like that.  Electryolisis leaves a little redness that will go away quickly, then a slight scab which goes away quickly.  Electryolisis is permanent but laser (I’ve been told) is not legally allowed to make that claim, & the laser dr. I go to was forced by a licensing board to stop making that claim.  She now has to say permanent hair reduction.
