I am new to this site. There is so much negativity in this thread. I don't see any women on here reporting their experiences with the laser treatments either.
From what I know: You have to have enough hair to begin with for the lasers to work. If you are already in deep with hair loss, the lasers probably won't be enough.
I am very young (23) and have been using the laser therapy for 4 months. I have seen new hairs growing and less shedding.
It may not be the best treatment for everyone, but just because it didn't work for you, doesn't mean it's a scam. It's certainly worth a try.
