How Long Does Dry Shampoo Last? [Does It Ever Expire?]

The popularity of dry shampoo has exploded in recent years, and it has enhanced the lives of people across the globe. Most of us have a bottle of dry shampoo stashed in our bathroom cabinet for those times when we are too busy to wash our hair even though it really needs it. If you're like many of us dry shampoo enthusiasts, you might only use it on occasion, and maybe you have had the same bottle for years. So the question is--how long does dry shampoo last, and can it actually expire? We've done the research to get the answer to this question.

Dry shampoo does expire even though most products won't have an actual expiration date stamped on the bottle. Beauty industry experts agree the maximum amount of time you should use the same bottle of dry shampoo is within two to three years since the quality of the product can become less effective as it ages. Another issue is that your hair can change over the years, and you might need a different product. Around the three-year mark, it's about time to throw out the old bottle and purchase a new one.

Dry shampoo is a great product if you use it for the recommended amount of time. Read on to learn more about the life expectancy of dry shampoo and other helpful tips to get the most out of every bottle!

Will Dry Shampoo Expire?

Dry shampoo is like every other hair care product on the market-- it does have a shelf life. In order to get the maximum product experience, you should only keep your hair care products for about two to three years. Some experts say that time frame only applies to products that haven't been opened. However, most agree that open or sealed, after three years, it's time for the trash.

Proper Storage

Since most of us keep our hair care products in the bathroom, you can be sure that your dry shampoo is subjected to heat and dampness if it is sitting out. The best place to store dry shampoo is in a cool, dark place, so the cabinet under the sink is probably better than on the counter. Proper storage will help keep your dry shampoo from expiring earlier than expected, and it will protect the quality of the product throughout its life so that you achieve the best possible results from day one.

Effects on Quality

The quality of your dry shampoo will likely be affected if you keep it longer than is recommended. The product might begin to smell bad or take on a different consistency than it originally had. If this happens, it probably won't work as well as it's supposed to, and you won't end up getting the desired results. No one wants hair that smells bad either!

Changing Hair

Your hair can change with time, so using the same product for several years might not be the best idea. Reevaluating your hair's needs every so often is a good practice. It's possible that the dry shampoo you used last year won't work for your hair type any longer. If you previously had oily hair and your hair has gotten dryer, you might need to purchase a different brand.

What Happens If You Use Expired Dry Shampoo?

If you decide to throw caution to the wind and use your dry shampoo after the recommended three-year life span, you can expect that it won't work as well as it once did.  The consistency of the product can become altered over time, and it might not go on your hair as evenly as before. Also, the smell of the dry shampoo can become a little off, resulting in your hair smelling the same --possibly bad--way.

Furthermore, the ingredients in the bottle can change over the course of several years, and since this might cause a decrease in the potency of the product, you won't get the same results as if you had a brand new bottle and your hair probably won't look as good. There is also the possibility that old hair care products can cause scalp irritation, so be on the lookout for any redness or itching if your dry shampoo has passed its expiration.

Why Is My Dry Shampoo Not Spraying?

In addition to not working as well on your hair, older dry shampoo bottles might not spray as well as they once did. If you find that your dry shampoo isn't spraying as it should, you can do a few things to fix the issue. If the product you are using is aerosol and possibly clogged, the first thing to do is to shake the bottle vigorously. Shaking it might loosen things up in the bottle. If that doesn't work, look at the nozzle to see if there is actually build-up you can scrape off with a toothpick.

Another option you can try is running hot water over the nozzle to see if that breaks up the clog. One way to avoid the problem of your dry shampoo not spraying is to wipe off the nozzle after every use so that there's nothing on the bottle to cause build-up or clogging. Using short sprays on your hair might prevent it from clogging as well.

How Do You Get Dry Shampoo Out Of Your Hair?

Whether you are using a brand new bottle of dry shampoo or one that's near the end of its life, it's a good idea to know the proper way to remove dry shampoo from your hair. One simple way to get dry shampoo out is to wash your hair with regular shampoo as you normally would.

If you tend to use dry shampoo a lot,  you might find that it has built up on your hair, so experts recommend rinsing your hair with lemon juice and water. Or you can try a mixture of apple cider vinegar and water. Mix five parts water with one part vinegar, spray it in your hair, then rinse.

To Summarize

Most experts agree that dry shampoo will last for about three years. It isn't terribly harmful to use it after the expiration date, but it might not be as effective. Furthermore, your hair might now have a need for a different dry shampoo. If you want to be absolutely certain that you are getting the most potent product possible, it's best to throw out the expired dry shampoo and spend the money on a new bottle that will create that beautiful look that you want.
