Are you mapping out your next incoming adventurous travel destination while also pondering whether, if you carry your dry shampoo along on the flight, will dry shampoo explode on a plane?
In alignment with all the issued directives by the TSA (Transportation Security Administration), dry shampoo has been allowed to be brought on a flight by the authorities. Stew it in your checked luggage or place it in your carry-on bag, and you will be fine to travel.
However, the stressful and potentially concerning situation that worries most passengers from takeoff to arrival is that they keep questioning if will dry shampoo explode on a plane.
To prepare you for any eventuality and to ensure you all stay fresh after leaving the plane, we will discuss the odds of your dry shampoo exploding on a plane during your flight.
Will Dry Shampoo Explode On A Plane?
It is understandable and completely justified for a traveler to ask whether dry shampoo will explode on a plane. Considering the continuous changes in temperature and pressure on a plane, items you are carrying are often prone to exploding, such as a fountain pen.
However, the case with a fountain pen and your dry shampoo is very different, and so are the odds of the later exploding. Regardless of the varying surroundings of an airplane, there is a very unlikely yet slight chance of exploding, igniting, or even leaking of a dry shampoo to take place on a plane. 
Two Types Of Dry Shampoo
Before we further emphasize the nitty-gritty of dry shampoo and its explosive qualities, we will be detailing the two typical types of dry shampoo that you are bound to encounter very commonly around you: powder and aerosol.
Everyone knows that, back then, it was required to sprinkle powdered dry shampoo on the bases of the hair to freshen and fluff it up. Voila, in an instant, you would get the volume and texture. But now, the powdered dry shampoo has transformed and is shaped like a spray.
Aerosol sprays provide much more control to users over their hair and the amount to be dispensed to ensure the hair does not look greasy. Spray dry shampoos are, in fact, a game changer for people who find their hair looking akin to powdered sugar over baked cookies.
Since these dry shampoos acquire rather divergent forms, the rules for carrying them on a plane too are different.
Powder Dry Shampoo Limit
Though there is no limit to carrying powdered dry shampoo on a plane, you should still weigh the container beforehand to check its weight and keep the final number under 12 ounces.
It is very unlikely for you ever to face trouble carrying powdered dry shampoo as they are not sold in massive amounts. Still, beware of the weight!
Aerosol Dry Shampoo Limit
Usually, aerosol dry shampoos are regarded as liquid products on a plane and, as a result, are made to follow TSA’s 3-1-1 rule. With this, the aerosol dry shampoo spray should be 3.4 ounces or 100ml and must always be placed and packaged in a clear, plastic, and quart-sized single bag.
Aerosol Dry Shampoo Exploding On A Plane
Returning to the focal point of our discussion of will dry shampoo explode on a plane. It is evident that powdered dry shampoo’s out of the picture and has left us behind aerosol dry shampoos. Will these aerosol spray bottles of dry shampoo explode?
Back in 2019, there was news of a dry shampoo exploding in a car, flighting 50 feet through a car’s window, which had many travelers worried about their dry shampoo on a flight. Aerosol dry shampoos will explode in certain situations, but as mentioned previously, not in a plane.
Dissecting the science of an aerosol container, you will find out the reason for aerosol sprays exploding is the change and increase in the inside pressure of the bottle, which looking for wanting to get out, explode.
Therefore, whenever the surrounding temperature of an aerosol bottle is raised, this prison breakthrough of the aerosol can explode and materialize. As the temperature may rise, so must the pressure.
As a warning, every aerosol spray bottle leaves a label for buyers to read, which indicates that you must never leave the container in a situation whereby it would be the direct subject of sunlight. Even when the aerosol container is empty, you are supposed to throw it away.
Thus, any danger of dry shampoo exploding on a plane is eliminated until and unless there is a situation where the plane is exposed to excessive heat, a fire has started, or anyone has pricked the aerosol container containing dry shampoo.
Trust the governing transport agencies and TSA when you carry dry shampoo on a plane, as the authorities have only concluded permissibility after conducting thorough research.
Additionally, the airlines take further steps to guard all traveling individuals in a plane against the risk of such items exploding. For instance, the area in an aircraft dedicated to holding luggage is pressurized, so the temperature is carefully regulated and minimized to prevent the explosion hazard.
