Does Shampoo Or Conditioner Expire?

Does Shampoo Or Conditioner Expire?

Regardless of the brand or which type of shampoo or conditioner you use. There’s almost always an expiration date, which is really normal because the ingredients used within the shampoo or conditioner will also start to lose effectiveness.

Does Shampoo Or Conditioner Expire? Yes, shampoos and conditioners do expire. Almost always, there’s an expiration date on the bottle itself and it’s there for a reason. Generally speaking, a bottle of shampoo or conditioner is good for about 1 to 3 years and when unopened 3 to 4 years. However, the ingredients within the expired shampoo or conditioner will lose effectiveness, which could possibly lead to damaged hair or even worse hair loss.

A couple of years ago, I used an expired shampoo without knowing it was expired. The problem with using an expired shampoo is that the bottle itself was already opened. When I started actually using it, I didn’t notice any difference from the scent or foam.

What I did notice after 1 year is that my hair suddenly was getting worse and worse. I do personally think that it’s mainly because of the shampoo that I used after the expiration date. Like I said before, the effectiveness might be gone after using it after the expiration date.

Keep in mind that an unopened bottle of shampoo or conditioner is generally still usable after 3 to 4 years. So when the bottle is unopened, there’s shouldn’t be a problem to use it after the expiration date. However, always make sure to look at the color and smell before using it yourself.

Is It Safe To Use Expired Shampoo Or Conditioner?

It really depends on the brand of the shampoo or conditioner. You need to look at what kind of ingredients/chemicals are used within the products and maybe even ask the manufacturer of the product.

I know from my own experience that it wasn’t bad for my hair, but I noticed that there weren’t any benefits either. The shampoo itself will still clean your hair, and the conditioner will still give your hair a protectant layer but not as you first bought and used it.

So what’s important to keep in mind when buying shampoo or conditioner is to not buy 10 or 20 at once because they will expire. Buy it one at the time so you know for sure that the bottle will be empty when you are going to buy a new one.

Will Expired Shampoo Or Conditioner Damage Your Hair?

No, probably not, but the shampoo or conditioner will also lose its effectiveness. So you probably won’t get any benefits either from using the shampoo or conditioner.

You probably won’t notice it at first if the product just expired 1 or 2 weeks, but I know for sure if you let it sit for 1 year or longer. The scent will definitely change, and it’s not pleasant, I can say.

Another thing to keep in mind is when using a shampoo or conditioner is that you need to know that you can’t contact the company itself if any problems occur. They will say that you used it after the expiration date and that it’s your own problem.

Shampoos and conditioners that are expired you use at your own risk. The shampoo or conditioner could possibly become contaminated with a dangerous level of chemicals. That’s why I always advise you to throw it out and stop using it immediately.

What Should You Do After It’s Expired?

Stop using it immediately because you don’t want to risk it. If the shampoo or conditioner gets into your eyes and starts becoming very irritated. You should contact a doctor right away. The chemicals could be extremely damaging, and it should be fixed immediately.

I know that some of the people reading this will still use it and live in their own bubble. What’s important is that you are responsible for your own actions, and I want everyone to be safe at all times.

Throw the expired shampoo or conditioner away and never look back at it again. Go to the department store or an online shop to purchase a new one. Shampoos and conditioners aren’t that expensive, and everyone should be able to afford them.

A helpful general rule is to only use the opened hair products for 18 months. After the 18 months, stop using them and purchase new ones.

Does Dandruff Shampoo Expire?

Yes, almost all types of shampoos have an expiration date. Even though there are lots of different shampoo brands for different hair types. It doesn’t mean that it’s not the case for dandruff shampoo.

A general tip that I keep in mind is not to use any products after 18 months of opening the dandruff shampoo. If you there’s no expiration date on the shampoo and it’s been over 18 months, you should smell it first.

Look at how it changed from the first time you used it and if it’s still okay. Use it once or twice max. But just buy a new dandruff shampoo because you never know what possibly could be done with that shampoo.

The expired shampoo has chemicals inside, which could lead to skin irritation or even worse hair loss. If that happens to contact a doctor immediately and ask for advice.

Do Shampoo Bars Expire?

Yes, shampoo bars can also expire, but as long as you keep it in a safe place. It should be safe to use. Generally speaking, you should keep the shampoo bar in a dry place, and you can still use it. A shampoo bar is usually good for 14 months, and by then, you should have probably used it already.

The only downside is that the scent will become weaker, the longer you let it sit after the expiration date. So remember yourself that you still have a shampoo bar somewhere stocked.

When you use a shampoo bar that’s expired, it’s not dangerous as long as there aren’t any batteries on it. Look at the shampoo bar itself and see if there’s anything different from the day you bought it.

If there is, then you could scrape it off with a knife or just throw it away. It’s up to you and what you do with it. I know that some people that can’t afford new shampoo bars every month will scrape the bacteria off and just use it again.


After all, I do not recommend at all to use any hair products after the expiration date. Even if you can’t afford a new one or have no others left. To reduce the risk of any harmful things that could possibly happen, buy a new one from the department store or online.

It shouldn’t be that big of a deal to go with unwashed hair for another day. If it’s a real emergency and there’s no other option left than using the expired shampoo or conditioner. I would just use it once and then throw it away after.

After using the product, I would go immediately to the closest nearby store and buy a new one. Go back home and shampoo my hair again just in case anything has happened. But, that’s just what I would do if there’s literally no other option left.
