Plot
Homer rushes out to buy a new hair growth formula, Dimoxonil, charging it to his health insurance at the power plant. He wakes up the next day with a thick mop of hair, and is soon given a promotion at the plant.
He hires a male secretary named Karl, who teaches him some self-confidence. Burns is impressed so much by Homer that he gives him the key to the executive washroom. Smithers is jealous and snoops through Homer's files, finding the bogus health insurance policy. When confonting Homer about it, Karl takes the blame and is fired.
When Bart spills the bottle of Dimoxinil, Homer loses his hair. Karl returns and convinces Homer that it was never the hair that made him successful. Homer gives a big speech (written by Karl) but no-one takes him seriously now that he has no hair. Burns demotes Homer back to his old position.
