Why Does Perfume Give Some People a Headache and Not Others?

Packed metro coach, 6pm, doors shut, the AC doing its best. Somewhere behind you, someone's perfume arrives before they do, and two stops later there's a dull ache building behind your eyes.

Perfume gives some people a headache because strong fragrance chemicals can irritate the nerves in the nose and head, and for people prone to migraine, smell itself can be a trigger. Usually that's an irritant reaction, not an allergy, though only a doctor can tell you which. Here's what's happening, what actually helps, and what doesn't.

Why does perfume give me a headache?

Perfume gives you a headache through three routes: irritation of the nerves in your nose and head, a stress response tied to how a smell makes you feel, and, if you're prone to migraine, sensitivity to odor itself.

The first route is physical. Some strong chemicals don't only register as a smell. They also stimulate the trigeminal nerve, which carries sensation from your face and head, and that irritation can show up as pain.

The second is emotional. Smell has a direct line to emotion, and Professor Amanda Ellison of Durham University describes how a stress response can widen the blood vessels in your head. That widening is felt as headache pain.

Allergist Matthew Greenhawt, writing for the Asthma and Allergy Foundation of America, calls it "an irritant effect and not an allergy." He puts it down to volatile organic compounds, chemicals that evaporate easily into the air.

Why do some people get perfume headaches and others don't?

Some people get them because sensitivity varies from person to person, and migraine is the biggest known factor.

The Association of Migraine Disorders says estimates range from about 25% to over 80% of people with migraine experience osmophobia, an aversion to smells, before, during or between attacks. It lists body perfumes among the most common smells behind it.

That doesn't mean perfume causes migraine. It means that if you're already migraine-prone, a strong scent can be one of the things that tips you over.

Two more things stack on top. Dose matters, because a perfume that's fine at arm's length can be too much in a shut lift. And sillage, the trail a perfume leaves in the air, means you're often reacting to someone else's spray, which you can't control.

Nobody can tell you in advance which perfume, or which note, will do it to you, so the only real test is your own skin and your own week.

Do lower-alcohol, higher-oil perfumes cause fewer headaches?

Not necessarily, and anyone who promises they do is guessing.

Here's what's true about the bottle. MYOP's 50% compound formulation means half of what's in the bottle is fragrance compound, so there's less room for alcohol and other carrier. Some people find the sharp first seconds of an alcohol-heavy spray harsh, and that part does change.

Here's what doesn't change. More compound also means more fragrance material in every spray. If the fragrance compounds are what bother you, a stronger formula doesn't dilute the trigger. It concentrates it.

That's why my rule for a 50% formula is simple: one spray is a full dose. Three is a mistake. With a formula this concentrated, a second and third spray don't add polish. They add more of whatever your head is objecting to.

MYOP perfumes are reformulated for tropical weather. That's a claim about how the formula behaves in Indian heat, not about headaches, and MYOP doesn't make one about headaches.

What can you do to stop a perfume headache?

Wear less, apply it further from your nose, and change one thing at a time so you can spot the culprit.

Start with the spray count. Most people spray pulse points like the neck and wrists because warmth lifts the scent, but that's also right under your nose. Try the chest below the collarbone or the inner elbow instead.

Then test properly. Try one perfume per visit, on skin, and give it half an hour before you decide. Keep a simple note of what you wore and how you felt. The Association of Migraine Disorders recommends a diary to find your triggers, and it works just as well for scent.

Compare your notes against each perfume's key notes. MYOP lists three for every perfume. At a Fusion table you choose the ratio of two perfumes, so if one of them is the one that bothers you, you can turn it down or pick a different pair.

When should you see a doctor about perfume headaches?

See a doctor if the headaches are frequent, if they get in the way of your day, or if you think you might have a true allergy.

Medical News Today, in an article reviewed by William C Lloyd III, MD, advises seeking help if migraine interferes with daily life, comes once a month or more, or isn't eased by medication.

A blog can explain the mechanism. It can't tell you what's causing your headaches, and a real allergy needs a proper diagnosis from a doctor. Tell them which scents you've noticed, and bring your diary. If a smell has ever left you unable to work, or you've started avoiding lifts, shops or offices because of it, that's reason enough to book an appointment.

Perfume isn't the only trigger on the list either. The same migraine organization names scented candles, air fresheners, cigarette smoke and cleaning products alongside it.

FAQ

Can perfume cause migraines?

It can trigger one in people who are already prone to migraine. The Association of Migraine Disorders lists body perfumes among the most common smells behind osmophobia. It doesn't cause migraine in everyone.

Is a perfume headache an allergy?

Usually not. Allergist Matthew Greenhawt calls it an irritant effect caused by volatile organic compounds. A true allergy needs a doctor to diagnose.

Why do I only get a headache from some perfumes?

Different perfumes use different materials in different amounts, and your sensitivity to each one varies. No one can predict which note will bother you, so a scent diary is the fastest way to find your pattern.

Does spraying less perfume help?

Often, because there's less fragrance in the air around you to react to. It's the simplest thing to try first, though nothing is guaranteed. With a 50% compound formulation, one spray is enough.

Are high-concentration perfumes better or worse for headaches?

Neither, as a rule. A higher concentration leaves less room for alcohol but puts more fragrance compound in each spray. MYOP's 50% compound formulation is reformulated for tropical weather, not for headache prevention.

Conclusion

No blog can predict what a scent will do to your head. A store can get you closer. Try one spray on skin, walk around for half an hour, and notice how you feel before you buy. If headaches are a pattern for you, say so at the counter and ask for help steering around the notes on your list.

Your nose decides. Test slowly. Make it MYOP.
