Woman with doubts about the expiration date of the oil

  • If you use expired argan oil on your hair, what will happen is that it won’t be able to moisturize, repair, or strengthen your hair.
  • Because the expired argan oil will have lost those properties that help strengthen and moisturize your hair.
  • But beyond that, nothing bad will happen to your hair. So, if you use expired argan oil it will just be like you haven’t put anything in your hair.

Let me guess.

You were tidying up your bathroom cabinet and you found a forgotten bottle of argan oil covered in dust.

And then you start to wonder. You ask yourself:  “what happens if I use expired argan oil on my hair?” 


The truth is that nothing will happen if you use expired argan oil on your hair.  Your hair won’t suffer any damage and you won’t ruin it. 


Because the most serious thing that has happened is that the argan oil has lost its aroma and its healing properties and vitamins.

 This is because we’re talking about a natural product, which doesn’t contain chemicals that could deteriorate and cause injury or irritation. 


So, if you use expired argan oil you won’t ruin your hair or damage your scalp. And that’s completely different from using, for example, an expired hair dye.

Why is that?

It’s because the dye contains chemicals that deteriorate, including the developer. And in that case, using an expired dye or developer could damage your hair and even cause injury to your scalp.


So now the question is: does it make sense to use expired argan oil on your hair?

And that’s what we’ll talk about next.


It doesn’t make sense to use expired argan oil on your hair

 Because even though it won’t harm your hair or scalp, it won’t improve your hair’s health either. 


In other words, if you use expired argan oil on your hair to moisturize or repair it, you won’t notice any change in your hair after rinsing it out.

Because it’s likely that some of its vitamins, amino acids, and fatty acids will lose their effectiveness.

So what’s the point of using it in your hair if the oil won’t repair or moisturize it the way your hair needs?

Now, it’s also important to check the expiration date and storage conditions of the argan oil.

Let’s start with the expiration date. According to the law, all food, cosmetic, and pharmacological products must have an expiration date in order to be marketed.


Because in this way, it’s easier to control how long a product should be used once it has been opened.

So, most likely, your argan oil bottle will have an expiration date. Generally, argan oil manufacturers recommend using it within five years.

And they recommend using it before that expiration date so you can take full advantage of the product’s benefits. But if you use it after that date, your hair won’t be in any danger. Because argan oil doesn’t degrade like chemicals.


Now, it’s also a good idea to take into account the way you should store argan oil. And we’ll go into this question in more detail below.


How best to store argan oil to preserve its properties

You should always store argan oil or any other type of natural oil, such as coconut oil for example,  in a place where it’s not exposed to direct sunlight or high temperatures. 


Because argan oil is sensitive to ultraviolet rays and heat. It’s also essential you keep it in a dark glass container because that will further slow down the passage of heat and ultra-violet rays.

And it’s vital you keep the container completely closed. As the oil has a low density, it’s volatile. So if it comes into contact with air, it will start to lose its most important properties.


Now, let’s suppose you found a bottle of argan oil and you don’t remember when you bought it. The expiration date is missing or illegible.

How can you check if the oil is in good condition or is getting too old?

What you should do is put a single drop in the palm of your hand.

Then check the following:

  • Does it have a pleasant aroma?
  • Does the drop have a watery consistency?
  • Is it free of stains and mold?

If you answered yes to all these questions, you can use argan oil on your hair even if it’s out of date or you suspect it might be.

Because the worst thing that could happen is that it won’t repair or moisturize your hair.

But, personally, I think if you want to use argan oil to moisturize or repair your hair, the best thing to do is to buy a fresh bottle and store it in the right way, to get all its benefits.



If you decide to discard an expired argan oil bottle and replace it with a new one, I recommend you store it in the refrigerator. Because this way all its properties will be better preserved and it will stay fresh for more than five years.
