Hi,
Saw significant hair reduction after 2 sessions using this device on buttock. Literally, there was only a few spots with hair throughout 6 weeks. I was amazed by the results! Then, after 3 months, I see a whole round of hair everywhere! I am wondering if the device doesn’t target the root of hair follicle deep enough and initial result was fake? Or whether it is normal and these hair were not in anagen stage and are rather totally new ones? How do I tell if the treatment is effective? 
Thanks
