How Long Does Shampoo Stay Good?(Does Shampoo Expire)

We spend some of our most relaxing times lathering up inside the shower, soaking our bodies in that warm trickling water; easing the aches of the day away. But, how many times have we tried to check the things that make up our shower house?

Definitely, we are asking about those bottles of shampoo. Some bottles from several years ago are still kept around, probably for a rainy day the moment you run out? Does Shampoo actually go bad or expire? Here’s all you should have knowledge of.

Does Shampoo Expire? To be honest with you, shampoo actually does go bad. In general, a shampoo can last for between twelve months and three years as soon as it has been opened. But it can last for three to four years when it has not been opened. Although some shampoo may not last up to this said period. 

How Long Does Shampoo Stay Good?

As said earlier, shampoo does go bad; the duration is majorly determined by the amount of chemical or natural ingredients that are contained in it.

As several brands have their own unique chemical or natural ingredients, it is suggested that you do away with shampoo bottles that you do not make use of frequently between a year or two.

When you set your eyes on an expired bottle,  you should have the ability to recognize it; the odor starts to become unpleasant, or the substances in it start to separate. 

Another sign you can use in recognizing an expired shampoo is that it would not work like it used to. That is, you have to continuously make use of the product in order for you to just get the same effect that you used to.

As we generally know, there is a method you can use in determining how satisfactory your shampoo is by just checking for the place where there is a list of ingredients on the label.

An icon which looks like a spam container or jar might be there, having a number which indicates the product’s shelf life.

This may be seen as “12M” or “24M.” In which 12 indicates that it can last up to twelve months, which is equal to a year after opening, and the 24 indicating that it can last up to two years after exposure to the environment. 

Even with a seal that is ironclad, shampoos which are left to stay without heat or sunlight will still most purely expire after three to four years. There will be a degeneration of the fragrance over time, which will most likely be as a result of oxidation. This also applies to preservatives.

However, we strongly recommend that your products are kept in a cool and dark place. If you feel the product looks like it can be used even after about three years, you are free to test it at your own discretion. (To be honest, I won’t try that because three years is kind of long!)

You can also test it out if it still has the same fragrance as it used to,  and if you need to use more and more of the product to wash your hair thoroughly. If you have chosen to make use of products which have passed the three-year mark, try to quickly use them up.

Now that you know that shampoo does go bad, here are some other things you need to know about expired shampoo. You will have more knowledge about expired shampoo, and you will also be surprised by some amazing things you can do with expired shampoo.

How to Know if Shampoo Has Gone Bad?

A sure way you can use in knowing if shampoo has become bad and is ready to be disposed of is an obvious change in its constituency and color.

If a bold or sometimes slight change is noticed by you in the consistency or color (in some cases both) of your shampoo, it is probably time for you to throw it in the trash bin.

I started probably simply because the color of your shampoo can change due to it being exposed to sunlight and sometimes air.

So, if you see some kind of change in its consistency and color, yet you’ve not been with that particular shampoo for a long period of time, it’s more or less likely because of exposure. Almost all products which react in this manner to air and light normally come with a warning, so you don’t need to be worried too much about that.

Some shampoos normally fail to completely create lather after they’ve gone bad, while some others will have a very bad odor, it’ll be very difficult to ignore. When any of these changes are noticed, breathe deeply, then throw it out now and accept the fact that it is time to get a new one!

After How Long Should I Opt for Another Shampoo?

I’m sure that you know that there are several types of shampoo, and each of them has several purposes. For example, there are the shampoo for sensitive skin, volumizing shampoo, cleansing shampoo, Straightening Shampoo and even the ones which are used for co-washing.

Almost all of us are guilty of the fact that we cling to products which are very good for us, and that’d m include shampoo. While there’s no issue for you to have a shampoo you love most; when you make use of just one continuously, you may make your hair tired and dull.

Just as you are meant to change your treatment to get rid of monotony and addresses several hair needs; it is best for you to change your shampoo for this particular reason also.

To give a response to your question, your shampoo can be changed every two months or immediately the bottle you are using now gets finished. Shampoo can also be interchanged in between wash days, which is dependent on the needs of your hair. 

It doesn’t matter the way you do it, as long as you do not stay with just one shampoo for six months or more. It is possible you are giving your hair too much of just one shampoo, and as they say, it is poisonous.

When the shampoo expires, it denotes that the chemicals in the shampoo have changed.  This can be in the instance that every healing nutrients in it have died or even worse, your shampoo has switched to a mixture lf hair killing chemicals.

This would most likely result in several hair problems like your hair as mild as dryness, and other issues as severe as hair loss. I do not feel there’s anything more to include; just throw it off if it’s expired.

When your shampoo emanates a smell which is not the same with its original smell, it is a clear indication that the shampoo has gone bad.
