The place I went to, in Columbus OH, is charging $1350 for a three-month session. I've seen the Laser Comb sold on the web for $650. The clinical trials are all with the headset units, not with the comb, so I'm not sure how effective the comb is.
There must be someone out there who's tried this, right?
