Maybe you only wash and condition your hair once a week or alternate between different hair care products.

However, a bottle of shampoo or conditioner can stay in the bathroom for a long time.

This may seem practical, but an important question arises: Can shampoo and conditioner expire?

The answer is yes, shampoo and conditioner expire and it’s a bad idea to use them after they expire.

There are some signs that your shampoo or conditioner has expired:

Component separation

When certain chemical components separate, you will notice the components forming layers, with the oils on top and the water in a separate layer.

Changes in texture or color

If the preservatives are no longer effective, the product may not be stable. This may result in a change in color or discoloration of the product.

Unpleasant smell

If the product starts to smell bad or has an unnatural smell, this is a clear sign that you should throw it away.

Using expired shampoo or conditioner can cause damage to your hair and scalp, so it’s important to be careful and replace them when you notice the above signs.
