The other is that there&#x27;s a critical difference between hair cutting - which is what this claimed to do - and hair follicle killing, which is what laser and IPL treatments do.<p>Existing treatments are supposed to kill follicles permanently.<p>This suggest it trims hair but doesn&#x27;t leave you permanently beardless.<p>They can&#x27;t possibly work the same way.<p>So I think KS did the right thing. Too many people have been using it in scammy ways, and that makes it less effective for anyone with a genuine product, talent, or idea to sell.<p>Having said that - the scams only work when you have a market full of people who don&#x27;t know enough about basic science or simple online research to check unlikely claims. And that&#x27;s been the real problem with KS, IGG, and the rest - it&#x27;s just too damn easy to make money from a few hours of 3D rendering to create a shiny sketch of a product that can&#x27;t possibly work, or (at best) can&#x27;t possibly be developed without far more investment.
