Everything in this life has an expiration date.

Everything has a beginning and an end.

  • Life
  • Your favorite novel
  • College
  • Even love. However, that’s a philosophical topic I’d rather not get into.


Therefore,  rosemary water also has a maximum duration. 


Rosemary water has a shelf life of three to four weeks.

To last that long,  it must be stored and kept in an appropriate place and conditions. 


And that place, in this case, is the refrigerator.

Obviously, if you prepare rosemary water for your hair, and expose it to the sun, it’ll lose its properties. As it’s a natural product, it has no preservatives.

What happens if you use rosemary water two months after preparing it?


 Most likely, nothing good or bad will happen. 


That is, your hair won’t fall out or stop growing.

But neither will you strengthen it or stimulate its growth or control oiliness.

 After two weeks, rosemary water is useless. 


What I can assure you is that your hair won’t exactly smell like roses if you apply rosemary water two months after you prepared it.

It’ll smell like decaying rosemary, to put it poetically.


So, to get the most out of the benefits of rosemary water on your hair, you need to keep two key things in mind:

  • Elaboration.
  • Conservation.

Of course, I’ll show you how to properly prepare and preserve rosemary water next.

That said, let’s move on to the proper preparation of rosemary water.


  • Rosemary could be fresh or dried
  • Three glasses of water



  • Place three cups of water in a kettle to boil.
  • Once the water reaches boiling point, remove the kettle from the heat and turn it off.
  • Add 100 grams of dried or fresh rosemary leaves.
  • Cover the kettle and let the rosemary water steep for ten minutes for the water to absorb the nutrients from the rosemary.
  • Strain the infusion and place it in a spray bottle for easy application to the hair.


 Once the rosemary water is cold, you can apply it to your scalp with a massage to help your hair follicles absorb it.

You’ll notice the changes in your hair after two weeks because it’ll be healthier, stronger, and shinier.

While it’s always recommended that rosemary water be fresh, there is no need to prepare it every time you apply it.

You can store it in a bottle to avoid bacteria, in a cool place, and not exposed to heat sources.

Therefore, my recommendation is to keep it in the refrigerator.

How do you remember when the rosemary water was made?


Appeal to an old trick we use in the salon to remember product expiration dates.

 Once you prepare the rosemary water, place a label with the date of preparation or write the date with an indelible marker on the container. 


This way, you’ll be able to control the expiration date of the rosemary water.



Rosemary water has a maximum shelf life of four weeks.

But you should keep it in a cool place, such as the refrigerator, and label the container with the date of preparation.

This way, you’ll always know when to discard old rosemary water.
