Some people who use the Sensepil get frustrated when they don’t see results immediately but users need to remember that the Silk’n Sensepil is a laser light-based home hair removal device and therefore it will not provide immediate results. Most people do not understand that laser hair removal is a more permanent solution but takes time to occur as opposed to something like waxing that removes hair immediately but ends with the hair growing back.
Instead of immediate results with the Sensepil you should expect to start seeing some results roughly two weeks after your first treatment. What generally happens is that hair continues to grow for roughly two weeks but then becomes weak at the root and begins to falls out on its own.
After this you may notice some regrowth but generally this is from different hairs. What happens with our bodies is that hair grows in three different stages with each stage being different hairs growing. Since the Sensepil (and all laser hair removal treaments) only works on hairs that are currently growing two-thirds of your hairs didn’t receive any effects from your first treatment and therefore subsequent treatments must be used once these hairs begin to grow.
Overall, you should expect to see some reduction in thickness after 2-4 weeks but in order to get the full results you need to be patient and should expect to wait quite a bit longer.
