Sabine argues that the barber’s claim is not true because the barber makes money by convincing people to buy the product.
This is the cookie-cutter “ad hominem” flaw, where the author attacks the source of the argument rather than the argument itself.
Here, Sabine dismisses the barber’s claim simply because the barber benefits from selling the product. Sabine never actually engages with the barber’s evidence, nor does she give any reason to believe that the product does not help prevent baldness.
