Is it true Latisse stops working after a year or so?

For a 1.5 years it worked wonderfully and I had amazing lashes then suddenly my lashes started to thin dramatically. I went back to see the Dr who prescribed Latisse and I was told a lot of her clients are experiencing the same exact results after a year or more of use. The Dr's own assistant admitted Latisse stopped working for her. So many people are experiencing the same results. Clearly Latisse does stop working. Google it and you will get a TON of results.
