As per this FDA literature, the Hairmax people would only be allowed to claim their product grows hair if it actually does. The FDA is allowing them to advertise as such because it has scientific backing (albiet not air tight). I think there has been something like 200,000 products that have applied for FDA clearance regarding being allowed to state that they grow hair, and only propecia, rogaine, and the hairmax were allowed. If they rejected 199,997 products it does grant the hairmax a little credibility i think. Also, the similar technology of the full sized dome salon lasers has been used for like 20 years in Europe and has substantial backing.
