Enstilar is an aerosol foam. The “flammable” warning isn’t a formality-it’s a real home-safety rule. While the foam and propellant are present on skin, hair, clothing, or bedding, they can ignite if you smoke or go near an open flame or strong heat source. This page explains the warning in plain language, lists common ignition sources people forget about, and gives a simple routine you can follow safely.

What the Flammable Warning Actually Means

Because Enstilar is dispensed from a pressurised can, it uses aerosol propellants that can catch fire. The risk is not only the can itself-freshly applied foam residue can also ignite before it fully settles. That means your safety plan has three parts: (1) apply in a safe place, (2) avoid ignition sources during and after application, and (3) store the can correctly.

Common Ignition Sources People Miss

Avoid these during application and immediately after:

Smoking (cigarettes, vapes) or being near someone who is smoking
Candles, incense, matches, lighters
Gas hobs, ovens, BBQs, fireplaces
Portable heaters, heat lamps, radiators, electric fan heaters
Hairdryers, straighteners, curling irons (especially if treating scalp/hairline)
Carrying out application near a running engine or in a garage with fumes

Practical rule: if you can smell fumes or feel strong heat, treat it as a ‘no application’ zone.

How Long Should You Avoid Flames or Heat After Applying?

The safest approach is to treat the risk window as “until the product has settled and there is no transfer risk.” In real life, this means: avoid smoking and open flames during application and for a period after, and avoid immediately going to high heat sources (cooking, heaters). If you apply before bed, make sure the foam is settled before getting under bedding to reduce transfer.

Reduce transfer risk (clothes and bedding)

Let the foam settle before dressing or lying down.
Use older clothing or a light barrier layer if treating larger areas.
Avoid applying right before activities that create friction (tight clothing, heavy exercise).

Storage and Handling Rules (Pressurised Can Safety)

The can is pressurised. Heat can increase pressure and raise safety risk. Follow storage instructions and keep it away from heat sources. Do not leave it in a hot car, on a radiator, or in direct sunlight. Don’t puncture or burn the can even when empty.

Safe storage checklist

Store at room temperature, away from direct heat/sun.
Keep out of reach of children.
Close cap properly and store upright if advised.
Do not store next to kitchen heat or bathroom heaters.

Do / Don’t Table (Fast Safety Rules)

Do	Don’t
Do apply in a cool, well-ventilated room away from flames.	Don’t smoke, vape, or use lighters/candles during or right after application.
Do wash hands after applying and keep away from eyes/face.	Don’t apply next to gas hobs, ovens, heaters, or fireplaces.
Do let the foam settle before dressing or going to bed.	Don’t use hairdryers/heat styling immediately after scalp/hairline application.
Do store the can away from heat and sunlight.	Don’t leave the can in a hot car or near radiators.
Do use the hub if you’re unsure about suitability or areas.	Don’t puncture or burn the can, even when empty.

If You Accidentally Expose Enstilar to Heat or a Flame

If the can heats up

Move it away from the heat source if it’s safe to do so. Do not puncture it. Place it in a cooler area and follow product instructions. If you suspect the can is damaged or leaking, avoid ignition sources and seek advice.

If foam residue is exposed to flame (near-miss)

Stop immediately. Remove yourself from the ignition source, check clothing/hair for residue, and wash the treated area if needed. If any burn occurs or you feel unwell, seek medical help.

Safe Use Depends on Correct Technique Too

Flammability is one safety layer. The other is using the correct dose and body-area boundaries, because Enstilar also contains a topical steroid. If you are unsure about thin-layer dosing, sensitive areas, or infection red flags, follow the how-to guide and confirm via consultation.

FAQs

Is Enstilar foam really flammable?

Yes. It’s an aerosol foam, so both the can and freshly applied residue can ignite near flames or strong heat sources.

Can I smoke after applying Enstilar?

Avoid smoking during application and immediately after. Treat it as a no-smoking period until the foam has settled and there is no transfer risk.

Can I use a hairdryer after applying Enstilar to my scalp?

Avoid heat styling immediately after application. If you treat scalp or hairline areas, heat tools are a common hidden ignition source.

Is it safe to cook on a gas hob after applying?

Avoid open flames and strong heat right after application. If you need to cook, apply your treatment well away from that activity and ensure residue has settled.

Can Enstilar stain clothes or bedding?

Residue can transfer. Let it settle before dressing or going to bed and consider older clothing if treating larger areas.

Can I keep the can in my car?

Avoid leaving it in a hot car. Heat increases pressure in pressurised cans.

What if I accidentally left the can near a heater?

Move it away if safe, don’t puncture it, and avoid ignition sources. If you suspect damage or leaking, seek advice.

Does flammability mean it’s unsafe overall?

It means you must follow aerosol safety rules. Used correctly, it can be a practical format especially for larger plaque areas.

Is flammability the only safety concern?

No. Enstilar contains a topical steroid, so area rules (face/folds/genitals) and infection red flags still apply. Use the hub for suitability.

Where should I start if I’m unsure?

Start with the MedCare hub to confirm suitability and get the correct plan.
