Quick answer: No. There’s no scientific evidence that Vicks VapoRub regrows hair, and as hair loss specialists we don’t recommend putting it on your scalp, because it can cause irritation or allergic reactions. A few of its ingredients may boost scalp circulation, but that alone has never been shown to grow hair.
Key takeaways
- Vicks VapoRub was formulated as a cough suppressant, not a hair product.
- Camphor, menthol, and eucalyptus may increase scalp blood flow, but improved circulation alone doesn’t regrow hair.
- Most “it worked” stories mixed Vicks with other oils (coconut, castor), so the Vicks itself can’t be credited.
- It can irritate the scalp or trigger allergic reactions if left on too long.
- Proven alternatives include minoxidil, finasteride, PRP therapy, or a hair transplant.
We’ve heard it all when it comes to hair growth solutions: endless theories, home remedies, and old wives’ tales about growing hair back faster, most of them unsupported by science. The latest one making the rounds involves Vicks VapoRub: yes, the same menthol gel you rub on your chest for a cold. Supposedly, rubbing it on your scalp promotes hair growth.
So we dug into where this claim comes from and whether there’s any truth to it. Below is what Vicks actually is, why people think it works, what the ingredients really do, and what we recommend instead.
What is Vicks VapoRub?
Vicks VapoRub is a menthol-based topical gel containing camphor and eucalyptus oil. It’s rubbed on the throat and chest to suppress coughing linked to minor throat and bronchial irritation, and the fumes are inhaled through the mouth and nose to ease congestion and help you breathe easier. It was formulated as a cough suppressant, not a hair product. So why do some people believe it grows hair? That’s what we wanted to find out.
Why do people think Vicks VapoRub grows hair?
The idea appears to have started in the African American community and gained traction on social media. Women and influencers began posting about rubbing Vicks on their scalp and seeing what looked like new growth after a few weeks, with some claiming up to an inch in a month.
One important detail is almost always overlooked: most people making these claims aren’t using Vicks alone. They’re mixing it with other ingredients first, such as essential oils, coconut oil, or castor oil, so any result is impossible to pin on the Vicks itself.
Is there science to back up these claims?
The answer lives in the ingredients. Vicks VapoRub has three main active ingredients (camphor, eucalyptus, and menthol), plus inactive ones including cedarleaf oil, nutmeg oil, petrolatum, thymol, and turpentine oil. Some of the active ingredients do have circulation-related properties in isolation, but “affects scalp circulation” is not the same as “regrows hair.” Here’s how each stacks up:
| Ingredient | Claimed benefit | What the evidence actually shows |
|---|---|---|
| Camphor | Stimulates scalp blood flow | May increase circulation to the follicles and support scalp health, but no study shows it regrows hair. |
| Eucalyptus oil | Reduces inflammation, boosts circulation | Some evidence for calming the scalp; none linking it to hair regrowth from Vicks. |
| Menthol | Vasodilator that “opens” follicles | Now thought to dilate blood vessels (it was once believed to constrict them), which may aid circulation, but improved blood flow alone hasn’t been shown to grow hair. |
| Thymol | (Preservative) | A strong antimicrobial. Dermatologists, including Dr. Krejci, have long recommended it for stubborn fungal toenail infections. Unrelated to hair growth. |
| Petrolatum, turpentine, cedarleaf & nutmeg oils | None | No hair-growth benefit, and some can irritate sensitive scalp skin. |

So, does Vicks VapoRub promote hair growth?
No. While a few of the active ingredients can stimulate circulation on their own, there is no scientific proof that using actual Vicks VapoRub grows hair. In fact, as hair loss specialists, we’d advise against putting Vicks on your scalp: it can trigger allergic reactions or irritate and damage the skin if left on too long, and it will leave you smelling strongly of menthol.
If you want options that actually work, several hair growth treatments are scientifically proven to help. Depending on the cause of your hair loss, that might mean over-the-counter or prescription options like finasteride or minoxidil, without the side effects Vicks can cause. Most hair loss is driven by androgenetic alopecia, and identifying the real cause is the first step to treating it. For a trusted medical overview, the American Academy of Dermatology is a reliable resource.
What about other home remedies for hair growth?
Plenty of products claim to stimulate hair growth, but it’s worth talking to a doctor before trying a random home remedy like Vicks. Even if a product contains an ingredient found in legitimate hair products, the other chemicals in the mix can change how it interacts with your scalp. Some medications do have proven off-label uses, but the safe path is to follow the guidance of the scientific and medical community rather than a viral trend.
A hair transplant specialist or board-certified dermatologist can identify what’s driving your hair loss and point you toward safe, effective treatments. No VapoRub required.
Frequently asked questions
Does Vicks VapoRub actually grow hair?
No. There’s no scientific evidence that Vicks VapoRub regrows hair. Some ingredients may boost scalp circulation, but that alone hasn’t been shown to grow hair, and dermatologists don’t recommend it.
Is it safe to put Vicks VapoRub on your scalp?
It’s not recommended. Vicks can cause allergic reactions or irritate and damage scalp skin if left on too long, and it isn’t formulated for use on the head.
Why do people say Vicks helped their hair grow?
Most people who report results mixed Vicks with other ingredients like coconut or castor oil, so any change can’t be attributed to the Vicks itself. Anecdotes on social media aren’t the same as clinical evidence.
What actually works for hair growth instead of Vicks?
Scientifically supported options include minoxidil, finasteride, and PRP therapy, along with hair transplantation for appropriate candidates. A board-certified dermatologist can recommend the right approach based on the cause of your hair loss.
