If you're interested in self-hypnosis, Steve G. Jones has the best recordings that I've found anywhere, you can access them through this link if you like:
Steve G. Jones - Self Hypnosis MP3 and Self Hypnosis CDs
Actually, I just recently ordered his hair re-growth MP3 myself, since I've noticed my hair getting a little thin up top as well. I can't give you any results as yet, since I've just started to use it, but I've had great success with some his other recordings.
Hope this helps,
