How Long Does a Can of Spray Last?

The answer to this question depends on the type of hairspray you are using.

Generally speaking, an unopened can of hairspray will last for up to three years. Once opened and used, the useful shelf life of the product is reduced to 18 months. This is because air and other elements can cause the product to break down, making it less effective over time.

Is It Safe to Use Expired Hairspray?

It is best to err on caution when it comes to expired hairspray. While the product may not be as effective, it is generally considered safe. However, if you notice any changes in color, smell, or consistency, it is best to discard them. It is also important to check the product’s label for any warnings or precautions that may be relevant when using expired products.

It is also important to note that older hairspray can become clogged or blocked, making it difficult to spray out of the container. If this happens, the product should be discarded and replaced.

Finally, if you are using aerosol hairspray, you should be aware that these products can become pressurized over time and potentially explode if not used with care. Therefore, it is important to read and follow all safety instructions when handling aerosol cans, especially when expired.

How Long Does Hair Spray Last Unopened?

When it comes to unopened hairspray, you can typically expect it to last up to three years. However, once you break the seal on the spray nozzle or open the aerosol canister, the product’s expiration date should be reduced to approximately 18 months. It is important to note that the product’s effectiveness may decrease the more time it has remained open.

Therefore, if you use hairspray often, buying a new one every 18 months is best. Additionally, non-aerosol hairsprays tend to have a longer shelf life than aerosol products, so you may get more use out of them if you opt for this option.

How Long Does Hair Spray Last Unopened?

When it comes to unopened hairspray, the shelf life can be quite long. Many manufacturers claim that their products can be stored for up to three years without going bad. This is large because aerosol hairspray is made with chemical preservatives that help keep the product fresh and prevent it from expiring.

Of course, it’s important to note that the expiration date on the container should still be followed; if the expiration date has passed, the hairspray should be discarded. Additionally, the product should be stored in a cool and dry place to ensure that it lasts as long as possible.

When Should You Discard an Open Container of Hairspray?

When determining when to discard an open container of hairspray, it is important to understand its shelf life. Generally, unopened hairspray can last up to three years before it expires. However, once the container has been opened, the product’s expiration date should be reduced to 18 months. To ensure the best results and quality, it is recommended that you discard your hairspray after the 18-month mark.

To determine if the hairspray has expired, you can look for signs like a change in color, an odor, or a change in texture. If any of these signs are present, discarding the product is best. Additionally, it is important to remember that hairspray should be stored in a cool and dry environment to prevent it from going bad quickly.

Do Different Types of Hairspray Have Different Shelf Lives?

Yes, different types of hairspray can have different shelf lives. Non-aerosol products like shampoos and conditioners are said to have a longer shelf life than aerosol sprays, which tend to expire sooner. Unopened aerosol cans of hairspray will last approximately three years, while an empty aerosol can only last 18 months.

However, non-aerosol products are said to last up to three years unopened and up to a year opened. It is important to remember that certain ingredients in hairspray can affect its effectiveness and shelf life. For example, if the product contains alcohol, it may expire faster than products with no alcohol content.

Can You Freeze Hairspray To Extend Its Life?

Hairspray is a styling staple that adds volume and texture to your hair. Unfortunately, it doesn’t have an expiration date, so you must be careful about how long you keep it around. You may be wondering if freezing your hairspray can extend its life.

The good news is that you can freeze hairspray to extend its life, but it’s important to note that you should only do this with aerosol cans. Freezing aerosol cans can make the contents last longer, but the same cannot be said for non-aerosol products.

When freezing hairspray, make sure you store it in a freezer-safe container. This will help protect the can from damage and prevent any leakage. Keep in mind that freezing will also cause the contents of the can to become thicker and less effective, so you may need to shake the can vigorously before use.

It’s also important to remember that freezing hairspray will not make it last forever; it simply extends its shelf life. So, even if you freeze your hairspray, ensure you use it within a reasonable amount of time.

How to Make Hairspray Last Longer

Hairspray is a great styling tool that can help keep your hairstyle in place for hours. But how can you ensure that your hairspray lasts as long as possible? Here are some tips for making your hairspray last longer:

  1. Store your hairspray in a cool, dry place. Extreme temperatures can cause the product to break down faster.
  2. Avoid storing the hairspray in direct sunlight. This can also cause the product to break down faster.
  3. Shake the can before using it. This will help mix the ingredients and make sure that the product works as it should.
  4. Use a mild shampoo and conditioner when styling with hairspray. This will help keep the product from building up on your hair over time, making it less effective.
  5. Avoid overusing hairspray on your hair. Too much of the product can make it less effective and cause it to break down faster.
  6. Replace your hair spray every 18 months, even if it’s still unopened. This will help ensure you get the best performance out of the product every time you use it.


In conclusion, hairspray can be a great styling product, but it’s important to know how long it will last. Unopened hairsprays can last up to three years, while opened cans can last up to 18 months. The shelf life of different types of hairspray can vary, so it’s important to check the label for the expiration date. Furthermore, it’s important to store hairspray properly to extend its life. These tips will ensure you get the most out of your hairspray and help keep your hair looking great!
