Explanation of What Rosemary Water Is

As you can understand from the name, rosemary water is water made of fresh rosemary leaves. As an option, rosemary essential oil can be used instead of the fresh leaves of this plant. But whether you use the oil or the leaves, it will not affect the efficiency of the final product.

Technically, rosemary water is the result of cooking rosemary leaves in distilled water. After being boiled for several hours on very low heat, the solids are then sifted out from the leaves.

During the boiling process, this herb breaks down, creating what is essentially a rich rosemary tea. This “tea” is what does tons of good things to your hair and scalp!

But since this method of making DIY rosemary water is rather time-consuming, you might want to use rosemary essential oil diluted in water to create this mix instead.

It will take you much less time compared to boiling, but the result will be the same as after using the boiled and sifted rosemary “tea”.

Importance of Knowing How Long It Lasts

How long does rosemary water last? This is probably the most common question people ask when they decide to make their own DIY rosemary water.

When you buy rosemary water at a drugstore, you already know when it expires since it’s indicated on the package. Usually, commercially made rosemary water can last for several months after you open it.

However, with the DIY mix made at home, it’s not clear when it can stop being helpful. Let’s try to figure out how long rosemary water can last, depending on where you store it and how it was made.

This way, you will know when this beneficial product may start turning unhealthy for your hair! As you probably know, natural and/or herbal essences and products often lose their beneficial properties and may work the other way if used after the expiration term!

How Long Does Rosemary Water Last Without a Fridge?

If you make your own rosemary water, note that it’s not a long-lasting product! Since it doesn’t contain any preservatives, it will expire pretty soon. Generally, homemade rosemary water doesn’t last longer than three weeks if refrigerated. But without the fridge, it may expire even faster!

Speaking of the commercially made product, its shelf life will be more extended, of course, due to the presence of preservatives in the mix. In general, rosemary water bought in a drugstore can last for a few months.

How Long Does Rosemary Water Last In the Fridge?

In the fridge, homemade rosemary water can last for up to three weeks. But no matter how tightly you seal it and properly it is stored, it must be discarded after four weeks of storage (even if you kept it in the fridge!).

How Long Does Homemade Rosemary Water Last?

If you make your own DIY rosemary water, the best place to store it is your fridge since it will slow down the degradation process. But even refrigerated rosemary water won’t last too long! Generally, this product can stay effective for a couple of weeks if it’s homemade.

Shelf Life of Rosemary Water

Knowing the product’s shelf life is essential, especially if you deal with the natural one that contains essential oils and/or other non-chemical components! Such products come with plenty of beneficial properties, but when expired, they can cause harm to your skin and/or hair! This is why, not to turn a remedy into a poison, you should always know how long it can last safely. For rosemary water, this rule of thumb works as well.

General Shelf Life

Rosemary water is generally not very long-lasting. If you have a DIY homemade product, it will last for a maximum of four weeks, but only if you keep it in the fridge! Otherwise, the lifespan of your beneficial hair care remedy will be twice shorter.

For sure, commercial rosemary water has a more extended lifespan since it often contains preservatives. Such a product can last for a few months.

Factors That Affect the Shelf Life

Rosemary water is rather demanding when it comes to storage conditions! If you want this product to last as long as possible, keep it away from heat sources and direct sunlight.

Factors That Affect the Shelf Life

Also, ensure your rosemary water is stored in a tightly sealed bottle in a cool and dark place. Heat, light, and exposure to direct sun can shorten the lifespan of rosemary water.

Storage Conditions

Rosemary water is rather sensitive, which is why proper storage conditions are mandatory. The ideal storage conditions include a dark and cool place away from any sources of heat. This is why you must keep rosemary water away from stoves, burners, heating objects, and other similar items. Also, don’t leave it in direct sunlight.

Type of Container

No matter whether you use rosemary water made of fresh rosemary leaves, or you have a product made of rosemary essential oil, it must still be kept in a tightly sealed bottle. This way, you will keep all the molecules of herbal essence in place.

To store rosemary water at home, we recommend you opt for spraying bottles with a tightly screwed top.

It’s not recommended to keep it in other containers, and moreover, you must never pour it from one container to another to use! Such frequent exposure to air will shorten the lifespan of the product!

Quality of Ingredients

The quality of ingredients used for your DIY rosemary water also matters! The higher the quality, the longer the water will last. Also, rosemary water made of high-quality ingredients will have a much stronger effect. This is why it’s recommended to use fresh rosemary leaves or rosemary essential oil of high quality from trustworthy brands.

Presence of Preservatives

Preservatives are used in cosmetics and various care products for hair and skin to extend the shelf life of all those shampoos, hair masks, creams, lotions, etc. Respectively, products with preservatives will also last longer.

But on the other hand, preservatives are chemical components, so if you strive for a non-chemical formula, opt for a DIY rosemary water that uses essential oils or a fresh rosemary herb. However, note that such a product will not last long.

Signs of Spoilage

When you use natural hair care products, it’s important to know how they look and smell if they are expired. This way, you can avoid applying a bad product to your skin or hair, which may result in irritation and other unpleasant aftermath. Below, we will explain what to pay attention to in order to figure out how your rosemary water is doing.

Signs of Spoilage

How to Tell If Rosemary Water Has Gone Bad

The easiest way to define whether your rosemary water has expired or is very close to it is to look at three essential factors:

  • smell
  • appearance/color
  • taste ( if it’s culinary rosemary water)

Read on to find out more about each of them. And note that these signs of spoilage may appear all at once or show up randomly and separately! So be attentive and cautious!


The freshly boiled rosemary water often has a light yellowy-green color. This is absolutely normal since the essential oils from the fresh leaves have just been released into the water! However, after a while, you may notice the mix turns darker red, resembling black tea (but still being translucent). This is also ok. When rosemary water goes bad, it usually turns much darker, like a very strong black tea.


Rosemary water of good quality has a rather strong herbal scent. But if you give your rosemary water a whiff and can’t sense anything, or the smell is barely there, it is very likely your remedy is already expired.


If you use rosemary water for culinary purposes or for making rosemary water to drink, and you are in doubt whether it is still safe to use, give it a try. Try a very little bit of rosemary water with your tongue to check the taste.

If it appears to be bitter, it’s most likely expired. See, the taste of good rosemary water is pleasantly refreshing and herbal!

Storage Tips

You might think that, since rosemary water is so demanding in terms of storage, it is also very challenging to keep it long-term. However, with a few simple tips, you (and your hair) can easily enjoy it longer! Below, we explain how to do it.

Proper Storage Techniques

The best thing about storing rosemary water is that it doesn’t require any complicated storage lifehacks! To keep it fresh and safe to use, simply place your rosemary water in a tightly closed container or spray bottle and keep it in your fridge between the uses.

This way, your homemade rosemary mixture should be fine for use for up to two weeks.

Tips For Extending the Shelf Life

You should realize that rosemary water won’t last forever, no matter how you try. This product (especially if it’s made of natural ingredients) is not very long-lasting. But still, with a couple of tricks, you can extend its shelf life to a couple of weeks more! This way, your rosemary water might stay useful for a whole month!

The best way to extend its lifespan is to keep the bottle/container with rosemary water away from direct sunlight. Sunrays can destroy the natural essential oils in the mix, making it absolutely useless.

Also, keep your rosemary water in a cool and dark palace. For this purpose, your fridge will be an ideal location! Finally, make sure your DIY rosemary water is kept away from heating objects like stoves and others. Heat is the same destructive for this product as sunlight.

Uses of Rosemary Water

Rosemary water is a highly beneficial product, but it can be used not only in the cosmetics and beauty industry. In fact, it is also often used in culinary and medicine! Below, we tell you more about each.

Culinary Uses

In culinary, rosemary water is used only if it’s made with natural herbs, not essential oils! For this purpose, fresh rosemary leaves and branches are used. In particular, they are added to the drinking water to infuse it with healthy elements that this herb contains.

As a result, this is not only a good way to make you drink more but also a lovely way to decorate the dining table when hosting!

In the beauty industry, rosemary has also gained respect. This herb is beneficial for hair, treating hair loss and even alopecia! Rosemary water makes your hair stronger and thicker, improving its growth.
