So I've listened to it a total of 4 times over the course of 4 days. I can start to see changes. I notice that the hairline has already moved down about a quarter of an inch, and there is a half-circle piece where the hairs are really thinned out, like, only about half of a half of the hairs are left in that one area.
At this rate, all the hair will probobly be gone in a month or so...
