You might only wash and condition your hair once a week, or you might alternate between a variety of products. A bottle of shampoo or conditioner may last you for a very long period in any scenario.
This can be beneficial in some ways, but it also prompts a significant query that most people seldom truly consider: Do shampoo and conditioner have an expiration date? It turns out that both shampoo and conditioner have an expiration date, and using either product after that point is not recommended.

Do conditioner and shampoo get old?
This is an easy one to answer: Yes, both shampoo and conditioner have expiration dates. This means that you should keep an eye out for the product’s expiration date as well as any indications that it may have outlived its usefulness.
The expiration date is typically printed on the bottle or elsewhere on the packaging, though you might need to check the box it was packaged in. Try contacting the manufacturer of the product if you can’t discover that information.
To find out more about batch identification or when it expires, it would be a good idea to contact the manufacturer.
How long before they run out does shampoo and conditioner?
Though the details differ from one product to the next, most shampoo and conditioners last at least six months or longer. A shampoo or conditioner bottle that has been opened typically lasts six months to a year, but if the bottle hasn’t been opened, it could last up to two or three years.
Shampoo or Conditioner Expiration Warning Signs
Separating the components
This indicates that some of the chemical elements have split apart. When this occurs, chemicals are typically split into layers, with water components in one layer and oil components at the top. The components will likely separate in the shampoo or conditioner immediately after you pour some of it out.
Texture or colour changes
This indication of out-of-date shampoo or conditioner will probably look odd or artificial, including having a new colour or clumpy texture. You might notice a colour change or deterioration since the preservatives are probably no longer working and the product is no longer stable.
Unappealing odour
You might want to check with the brand or manufacturer if you detect an offensive or unusual odour in the product.
