* Candace, as a wird female case, uses a machine her brother's built for her in order to fix her hair (that she herself ruined by trying to follow online videos on how to easily do your hair). Of course, she can't wait the designated time and decides to turn 30 mins into 10 seconds by cranking up the level. Cue Candace being [[spoiler: mistaken for a tangerine orangutang gorilla]].

It seems that a man's greatest fear is losing his hair, and once it's gone, it's gone for good. Which is why a bald character is bound to try using some kind of product that promises to grow back their hair. [[ExactlyWhatItSaysOnTheTin This product never works]]. Or rather, it usually works too well, with way more hair sprouting than necessary, and often in places that it wasn't wanted. Other side effects may occur as well, including, but not limited to, the hair turning an unnatural color or what little hair was left falling out completely.

* Hazmat of the ''WhatelyUniverse'' is cueball-bald due to his failed hair tonic. Aquerna arranges for Phase to look at it and plans are put into place to sell it as a hair-removal application for women.

* {{Seinfeld}}: George Costanza's Chinese baldness cure.

* A DonaldDuck comics story "Black Wednesday", written by CarlBarks features Uncle Scrooge selling hair tonic to the "Chillyboot Indians", which actually causes baldness. Donald later returns with a hair tonic made by Gyro Gearloose; that one works too well.

* In the Canadian family film ''The Peanut Butter Solution'', a boy loses his hair after seeing ghosts, then grows it back with the titular solution. It doesn't know when to stop, of course.

* Billy in the GrimmAdventuresOfBillyAndMandy tried some hair tonic and ended up growing hair all over his body looking like a Bigfoot. It turns out that all he has to do was wash it off.
* Dexter makes a hair tonic for Dee-dee after she accidently cuts off one of her pigtails. Despite repeated warnings to use only one drop, Dee-Dee uses the entire bottle. Three guesses what happens next.

* The title charater in ''The Witch's Son'' by VivianVanVelde goes through several variations on regrowing a girl's golden hair, [[HillarityEnsues none of which work.]]

* ''GaiaOnline'' has an item called Gro-gain: "New and improved, all natural formula guarantees DRAMATIC new hair growth, or your money back!" It can give you a huge mustache on your crotch, "Coiling Pit Hair", "Unforgivable Leg Hair", "Evil Hair" on your head, and more. It can even turn you into a "Fearsome Hairy Beast". It even caused a child character to develop a [[TheLeisureSuitLarry LeisureSuitLarry]] alter ego and experience {{rapid aging}}.
