Yes, you read it right, I've spent at least $10,000 on laser hair removal and it has not worked at all!
The first round of treatments through UCLA Medical Center were costly and worthless. I spent $500 per series of treatments, and I had a LOT of treatments. I was trying to get a more "acceptable" bikini area if you know what I mean. It was very embarrassing, but that's easy to forget about. The $$ that I wasted is not quite so easy to forget!
They used three different lasers on me and none of them removed the hair for any period of time. By the time I would go back for subsequent treatments, the hair would already be back. Finally one of the doctors told me that I had "refractive hair and they couldn't do anything for me". Supposedly, that's when your hair reflects back as a different color when the laser hits it and the laser can't "zero in" on the melanin.
I went to two other practitioners who performed countless treatments on my abdomen and chin/neck with different lasers, all to no avail. It hasn't done any good. I still clog the drain every time I shave! :)
