Does Shampoo Expire? How Do You Know?

Does shampoo expire? This is probably one of the most common questions that we all have in mind. The problem with most beauty products is that the manufacturer often doesn’t include the expiry date.

Skincare and beauty products have the information but not with shampoo. You may not find the information on the bottle, but rest assured that shampoo has its own expiry date too.

The Facts about Shampoo’s Expire

does shampoo have an expiration date
In general, most shampoo will expire within 12 months after purchase although the label may not say so. You see, the formula (of the shampoo) usually contains water. This makes the shampoo prone to bacterial existence and infection. Many manufacturers may include (hard) synthetic preservatives to make their products go as long as they can. But any water-based product is bound to have the fast expiry date.

What about shampoos using natural plant-based preservatives (such as radish root or rosemary oil ferment filtrate)? They even expire faster – they can only last for several months. That’s why it is always recommended to do some researches about the products you are using – how safe the products are? Do they use preservatives? If they do, what are they?
