"M is for Minoxidil,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. 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. Truth in Television: most over the counter baldness remedies don't work or don't work well, especially when used once the condition is sufficiently advanced. Prescription systemic treatments are somewhat more likely to work (though they also come with bad side effects for men — namely, they work by reducing testosterone and/or its effects on the body in most cases). The gold standard of baldness treatment is hair transplant with ongoing maintenance, as it is the most likely to actually be worth the money spent on it with the least systemic side effects. For similar forms of hair-related hilarity, see My Hair Came Out Green and occassionally Kaleidoscope Hair. See also All-Natural Snake Oil for the same principle applied to more serious ailments, not usually played for laughs.

- In a fake ad that is interrupted by the Energizer Bunny (the actual product being advertised), a man hawks a hair tonic that's way too effective: it causes hair to sprout not just on his head, but also on his back when the excess spills and even on the concrete pool surface when the Bunny knocks the bottle over.
Anime and Manga
- On Ranma ½ Genma is quite embarrassed about his baldness and has tried all kinds of cures. This doesn't stop him from trying new remedies. There was the one that only works when he's angry, the one that comes from a one-of-a-kind dragon's whisker, and so forth.
- Mahou Sensei Negima! has a female variation, when short-haired Ako thinks she should grow her hair out to be more attractive. A (not so) helpful denizen of the magic world promptly gives her a magic hair-growth potion, which works perfectly for all of a minute before the hair begins to engulf her.
- An early InuYasha story has two demon brothers kidnap Kagome. She thinks they simply want to eat her, but it turns out one of them is severely balding and embarrassed about it, and he has heard you can get a hair growth potion by boiling down a human maiden. At hearing this, Kagome angrily insists they eat her instead. (Not 100% really this trope, since we never learn whether the potion works — but the kidnapping does lead to the demon losing his last few hairs — before he is killed.)
- In the gag manga Urayasu Tekkin Kazoku, 43-year-old Daitetsu Osawagi has a bald spot and fearing of becoming completely bald like his father.

Chapter 51 in the Ganso series showed him losing faith in his hair tonic dumping every bottle in his hair-clogged sink. The tonics cause hair in the sink to grow out of control and start to consume Daitetsu and the house.

- In an Archie Comics comic, Professor Flutesnoot invents a hair tonic which apparently does a great job growing one's hair back. Though he stresses that he's still testing it, Mr. Weatherbee insists on secretly using it on himself. By the end of the comic, it's revealed that the tonic makes one grow a freakish amount of hair, with pouring water on it being the only way to stop the process.
- In another comic, Jughead has created a hair tonic and tested it on a cue ball. Weatherbee gets it of course, and pretty soon has a headful of hair again. Flutesnoot then reveals that he analyzed Jughead's formula, and that a key ingredient is swamp muck; Weatherbee has a headful of moss.
- In The Smurfs story "The Great Smurfette", Gargamel was reported to have given a bald person a potion for growing a full head of hair, but the side effect is that it has given the person a chronic case of incurable hiccups.

Drebin has long hair, and when Nordberg appears, he has an Afro so huge he can't fit through the door. After the movie returns to the present, Ed says to Nordberg, "I do remember! You were one of the first cases for minoxidil." note
- Body Bags: In the "Hair" segment, a balding guy goes to a new clinic to get an experimental hair transplant. It works, but then his hair keeps growing all over his body.

- In Charlie and the Chocolate Factory, one of the works-in-progress in the Inventing Room is Hair Toffee, which gives its eater a full head of hair plus a mustache and beard, a half hour after it's consumed. It's still a work in progress because currently it's too powerful — when an Oompa-Loompa tested it, "In the end we had to use a lawn mower to keep it [the hair] in check!" according to Willy Wonka. Also, it apparently has the same effect on men and women, and even works on children — which is his intention, in order that "there'll be no excuse any more for little boys and girls going about with bald heads!"

Live Action TV
- An episode of Doctor Who called "Planet of the Ood" has a similar situation. Ood Sigma constantly hands his boss, the villain of the episode, a drink which he claims is hair tonic. It turns out to be ood-graft which eventually transforms him into an Ood.

- In (what turned out to be) the final episode of The Brady Bunch Bobby gets some mail-order hair tonic to sell, which turns Greg's hair orange. In the memo attributed to Robert Reed about how weak the show's internal logic had become, he complains about this in particular:
Why any boy of Bobby’s age, or any age, would be investing in something as outmoded and unidentifiable as “hair tonic” remains to be explained. As any kid on the show could tell the writer, the old hair-tonic routine is right out of Our Gang. Let’s face it, we’re long since past the “little dab’ll do ya” era.
- A Good Eats episode on celery has a sketch of a celery drink just made regrowing hair, then shows Alton paying the man whose hair supposedly grew back in private.

- Another episode features an accidental hair tonic made by the daughter experimenting with paint. It works wonders, but has the nasty* side-effect of making the users horny for their wives.
- In a Dream Sequence on The Dick Van Dyke Show Rob's hair turned into lettuce, because he was given a baldness preventativenote that was basically oil and vinegar — aka salad dressing.
- Two and a Half Men feature 'Captain Terry's Spray On Hair' as well as pills, both of which Alan try before going on dates. The first ends up running down his face when warm and the pills cause bizarre follicle growth.
- One Bloom County arc featured a compound made from cat sweat, originally intended as an underarm deodorant, which caused massive hair growth wherever it was applied. Its creator immediately turned it into a hair tonic instead. Sales were ridiculously, dangerously good for a while... and then customers' hair started falling out. As in, all at once, poof-gone-you're-a-bowling-ball. And it makes you start saying "ACK!", presumably because it was made from Bill the Cat's sweat.
- It's happened a few time in Curtis, often thanks to the titular character's misuse of a Flyspeck Island substance.

Obviously, this quickly backfires, and he desperately tries to get his hair back, leading to Skull giving him a hair growth potion. Unfortunately, Brent uses up most of the bottle, which was supposed to be diluted in water first, and he immediately grows hair so long he looks like Cousin It, including on his hands.
Brent: My scalp feels tingly...
- Gaia Online 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 Casanova Wannabe alter ego and experience Rapid Aging.

On the other hand, the hair tonic he used earlier in the same short to grow him a beard worked perfectly.
- In The Simpsons episode "Simpson and Delilah", "dimoxonil" actually does grow hair on Homer's head, but the Snap Back to baldness comes because Bart spills Homer's bottlenote and he can't afford any more. Hasn't minoxodil (of which dimoxonil was obviously a parody) become a lot cheaper than it was in 1990? Homer could probably afford it now! There's also the affordable tonic the doctor offers Homer because he cant afford the 1000$ dimoxonil, which the doctor even states that any hair growth Homer would experience while using it would be purely coincidental.
- The Simpsons used this trope twice. At the end of the episode "Barting Over" Homer acts in a commercial for Viagra-gaine, a drug that "gives you hair and what you need down there" and has side effects including loss of scalp and penis.
- The Mother Goose and Grimm cartoon had a hair tonic which could grow hair on billiard balls, as advertised...but it couldn't grow hair on anything else.

- Courage the Cowardly Dog:
- In the episode, "Hothead", Eustace applies for an experimental hair tonic, with the warning that the recipient not be angry when in use. Little does Eustace know, is that every time he uses the tonic, it amplifies his anger to the point that he can cause explosions (and to add insult to injury, he doesn't grow any hair other than one long strand at the end of the episode, which immediately wilts again, making him so angry he blows up the house with himself inside it, Courage escaping with Muriel at the last moment.)
- Another episode has Eustace's mother be involved in human experimentation for various hair related products. The twist here is that their method DOES work, extremely well in fact, causing people to grow huge amount of hair to be used in experiments. At the end, after Courage has freed Muriel from her unwilling participation, Eustace returns to the farm, now covered in a thick head of hair, and holding fistfuls of cash for his participation. This is pretty much the high point of Eustace's life on the show.
- Gargamel and Brainy learned this lesson the hard way in The Smurfs episode "Symbols of Wisdom" when they both try to grow their own beards, since it caused their beards to grow so long. Also, Papa Smurf had Hogatha's hair spell in "Smurfette's Golden Tresses" purposely altered by giving her bear fur dyed in the color of Smurfette's hair, which caused the hair to grow so long on Hogatha's head that it covered her face and immobilized her.
- Phineas and Ferb has a female example in "Bad Hair Day", when Candace uses a machine her brothers built for her in order to fix her hair after a botched attempt to cut it herself.

Cue Candace getting covered in hair and being mistaken for a tangerine orangutan.

- Gasp: In "Hair of the Fish", Gasp buys a Peruvian hair tonic online in an attempt to cure the bald patch he accidentally created on Catflap. After he is doused in the tonic, Gasp ends up growing hair all over his body. Gasp, it should be pointed out, is a fish.
- Johnny Test has this happen due to a couple of Susan and Mary's inventions. The Zoomer Groomer could create mustaches and worked as advertised, but Bling-Bling Boy overused it, became very itchy, and grew thick hair all over his body. Another episode had Susan and Mary use a hair tonic which worked too well, eventually leading to them looking like a woolly mammoth.
- An episode of Hi Hi Puffy AmiYumi had Kaz ordering a hair tonic to overcome his male pattern baldness, and it ends up frequently turning him into a werewolf who terrorizes the girls' cats.

- My Little Pony: Friendship Is Magic: In "It Isn't the Mane Thing About You", when Rarity loses most of her mane in an accident involving misuse of a powerful magical cleaning product and tries to grow it back, it turns out that hair magic is ridiculously hard to use. When Twilight Sparkle and Starlight Glimmer (two of the setting's most powerful magic-users) try to use magic to restore Rarity's hair, the first spell they try takes the hair from another pony and transfer it Rarity (before said hair simply shatters), the second creates wooden hair from a chunk of a door, and the third causes Rapunzel Hair to appear on the castle's walls.
