M is for Minoxidil,
A hair-raising drug;
Takes a year to grow fuzz—
Give it up! Buy a rug!

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.
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.

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 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 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.
- To be fair, it would have if the kid hadn't included so much peanut butter. And let's not get into his friend, who put it on a certain other place...Yeah...
- In The Naked Gun 33 1/3, there's a flashback with the detectives in what's supposed to be the 1970s.

You were one of the first cases for minoxidil." note

Live Action TV

- 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.
- Seinfeld: George Costanza's Chinese baldness cure. Whether it actually works is moot, because it smells horrible and he never manages to keep it on his head long enough.
- One early episode of Married... with Children had Al and Steve freak out about their baldness and try an experimental "tonic" to reverse it. Not only did it not work, but Al's dog Buck took to the stuff better than their hair did (they were actually using some kind of dog food in their hair, and the doctor who sold it to them was a quack).
- 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 folical 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.
- Doc Rat featured Mr Pigg complaining to the chemist that the tonic he'd purchased which promised to "add body to your hair" had caused him to sprout hair everywhere. Turned out he'd read the label upside down; it actually said "adds hair to your body".
- 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.

- In the Looney Tunes short Rabbit of Seville Bugs Bunny rubs and sprinkles a number of tonics (including fertilizer) on Elmer Fudd's scalp, only for flowers to sprout from his head instead of hair. 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!
- 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.

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 makes him so angry he destroys the entire house.
- 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.
