Many people have just considered if does shampoo expire? The answer is yes. Just like any other product, it has one. Shampoo can last anywhere from six to twelve months after the expiration date, but it’s best to err on the side of caution and replace it sooner rather than later.
Just check the label, and when it says on it, there is a use-by date, and that’s the one you should check to see if it needs to be replaced.
Is There A Shampoo Expiration Date?
The short answer to that question is yes. The law doesn’t require manufacturers of personal care products, such as cosmetics and skincare, to mark a product with an expiration year.
Many will also include a period following opening suggestion. According to FDA Trusted Source, this is generally a period for a product to be expected to function as it should or is safe to use.
Look at the bottom of your shampoo bottle to find a period. You’ll find a symbol that looks similar to a small container with its lid off if your product has a use-by date.
The number will have the letter M on it, which is likely to be:
- 12 M
- 18 M
- 24 M
The manufacturer says that you must use a shampoo bottle within a specified period. This could be 12 months, 18, or 24 months.
Sometimes, a product does not provide information about expiration dates, time after opening, shelf life suggestions, or shelf-life guidelines. This makes it harder to know when to throw out a shampoo bottle.
You can still inspect the product to determine if it is damaged.

Your Shampoo Ingredients Matter
The ingredients of shampoo will determine its expiration date. This will vary depending on the brand and formula, but you can expect that most shampoos contain the following:
- Sodium lauryl sulfate
- Sodium Laureth Sulfate
- Citric acid
- cocamidopropyl betaine
These ingredients are found in shampoos and can do many different things. These ingredients are cleaning agents and foaming agents and extend shelf life. The benefits claimed by shampoos vary in their quantity. They can prevent dandruff, eliminate split ends, protect from frizz, and repair hair.
It’s important to remember that oxygen can slowly degrade the abilities of these ingredients when you open a shampoo bottle. The slow growth of bacteria can be caused by oxygen, which may react with the shampoo’s ingredients.
How Do You Know If Your Shampoo Is Terrible?
Gina Rivera, founder, and CEO of Phenix Salon Suites says that shampoos without expiration dates or aren’t usable may be a sign to watch out for.
Although some shampoos are marked with an expiration date (which is more of a suggestion rather than a rule), it’s not a mandatory requirement. A few simple tests will help you determine if your shampoo is terrible.
It smells. It’s probably past its prime if it smells like lavender fields now but smells like mushrooms or wet dogs. Toss it.
Pour it. Another sign that it is past its expiration date is a runny or watery texture. It is losing its rich texture and is not safe to use. It should be thrown away.
It should be lathered. Add a little water to make a lather. It should not be bubble or foam-like. It does every day.
What Factors Can Impact The Shelf Life Of Shampoo?
Make sure you:
- Once you are done with it, close the lid completely.
- Avoid direct sunlight and high heat.
- Keep the shampoo bottle in cool, dark places.
- Reduce your exposure to water droplets and other products contaminating the product.
Rivera said it is essential to know that organic and sulfate-free shampoos may have shorter shelf lives. She explained that this is due to the absence of preservatives and the addition of more healthy-based ingredients.
Is Shampoo Safe To Use If It Has Expired?
Rivera stated that expired products undergo chemical changes, meaning they are no longer effective at high levels.
Shampoos that are past their expiry date can cause hair to look duller and less clean.
Rivera said that an expired shampoo could cause irritation or itching to your scalp because of the chemical change.
What About Other Items In Your Bathroom?
Bathroom products can quickly go wrong. It is essential to regularly check your beauty and health products for expiration dates and get rid of expired ones.
Here are some other products to look at, in addition to shampoo:
Makeup. The clock begins to tick once you open an eyeshadow container or lipstick tube. Your makeup might come with a label at the back that says Period after opening. You should check this before you use the product.
Most cosmetics last between 3 and 24 months if it does not have a label. According to FDA Trusted Source, lipstick is the most likely to be thrown out after three months and mascara the next at 18 to 24 months.
Toothpaste. Toothpaste must have an expiration date. Check the toothpaste tube and the box to find the expiration date. Always lookout for the American Dental Association Seal of Approval for maximum safety and efficacy.
Sunscreen. Sunscreen should have an expiration date. The FDA Trusted Source recommends that sunscreen be thrown away after three years. The sunscreen’s ability to protect you against the sun may be compromised if you continue using it after the expiration date.
Hydrogen peroxide. Hydrogen peroxide should be used within 2 to 3 years of purchase. It’s not effective after opening the container.
Use rubbing alcohol. Use rubbing alcohol before the expiration date printed on the label. This will ensure that it is effective. This usually occurs between 2 and 3 years after purchase.
Disposing Of Expired Shampoo
It would help if you disposed of your shampoo correctly once you have determined that it is no longer in use. It is tempting to throw out the rest of your shampoo and not recycle it or throw it away.

It is best to empty the shampoo from the bottle and put it in a new container before bringing it to the hazardous waste facility. The original bottle can be wiped clean, recycled, or thrown in the trash.
However, if you don’t have recycling facilities in your area or your local area holds Household Hazardous Waste disposal events only a few times per year,
You can throw away the entire bottle of shampoo if it’s not in use. The shampoo will still end up in the trash, but the plastic container should contain the shampoo and keep it from leaking out.
Is shampoo good after 5 years?

What happens to expired hair products?
Although expired hair products won’t cause hair damage, they won’t work as well when they’re new. You might also notice a foul-smelling effect, which can cause your hair to smell.
It’s essential to know how to buy shampoo properly to avoid wasting money on products you don’t need. You should keep an eye on the expiration date and purchase a new one when you notice that it’s nearing the end of its life.
