Harnessing the Power of Nature: Using Rosemary Oil for Hair Growth

All over TikTok, Instagram, YouTube, and well, all over the internet, people are raving about the hair-boosting benefits of rosemary oil. This is just one of the hair hypes at the moment, along with things such as hair botox or keratin treatment.

The claim is that rosemary oil can work to stimulate your hair follicles which results in new growth. This means your hair grows longer, faster, and appears thicker due to all the new growth.

But how does this work? And why?


The Power of Rosemary Oil: Its Impact on Hair Growth

Some studies show that rosemary oil can be as effective as for hair growth – the key ingredient in products such as Rogaine.

The benefit is that rosemary oil is cheap, readily available, and a more natural alternative to harsh chemicals.

Rosemary oil is also typically used in conjunction with a scalp massage, which is practised in many cultures as part of beauty and hair-washing routines. So many people like that it fits right in with their existing wellness practices!

You can usually buy this oil at supermarkets, beauty supply stores, health and wellness shops, or essential oil vendors.

How to Apply Rosemary Oil for Hair Growth

Want to know how to make your hair grow faster using rosemary oil? Here are three ways you can use your rosemary oil to get long, luscious locks starting now.


Massaging Rosemary Oil Directly Into the Scalp

One of the quickest and easiest methods for using rosemary oil for hair is diluting it in a carrier oil and massaging it straight into your scalp.

A carrier oil should be a neutral, moisturising oil that contains no fragrance or essential oils. Rosemary oil on its own can be a little bit too strong and irritating, so mix a few drops with almond oil, jojoba oil, coconut oil, or olive oil for a soothing concoction.

Some rosemary oils are already diluted with another oil, so check the label and make sure it’s the right mix for you.

Then, you’ll want to use your fingertips to massage the oil all over your scalp. If you have areas where you’re concerned about thinning hair, feel free to concentrate on those a little extra!

You could also use a scalp massager to really work the oil in and bring more blood flow to your hair follicles – which can also boost hair growth. 

Ideally, you want to apply a thin layer of oil all over your scalp, get the blood flowing to your follicles, and have a nice relaxing scalp massage while you’re at it.

Then, leave the oil soaking on your scalp for about 2 hours. Some people prefer to leave it longer, but it can be a bit messy and a buildup of the oil on your face can lead to breakouts.

If you do want to leave it longer, then pop on a shower cap and shampoo out!


Mixing Rosemary Oil Into your Shampoo or Conditioner

If you want to kill two birds with one stone, another option is to mix a few drops of rosemary oil into your haircare products to give them some growth-boosting properties.

Shampoo is ideal to mix a few drops of rosemary oil into because it gets massaged all over your scalp anyway! No need to dilute into a carrier oil, the straight rosemary oil can go right into your favourite shampoo and then onto your head.

However, putting rosemary oil into your conditioner isn’t the best idea… Your hair grows from the roots so that’s where you want to put the active ingredient.

Making Your Own Shampoo with Rosemary Oil

Do you love a DIY? Here’s a quick how-to on making your own rosemary oil shampoo at home!

Gather up the following ingredients:

  • 1/2 cup of liquid castile soap or mild shampoo
  • 1/4 cup of water or herbal infusion (like home-brewed rosemary tea)
  • 10-15 drops of rosemary essential oil 

In a bowl, combine the liquid castile soap and rosemary oil and stir to combine them gently.

Gradually add your water or herbal infusion to the mixture while stirring continuously. Once everything is mixed properly, pour the shampoo mixture into a clean, bottle and it’s ready to use!

The Magic of Rosemary Oil: Unveiling Its Role in Rapid Hair Growth

So, when we get down to it, what can you expect when using rosemary oil for hair growth? Here’s what you need to know in terms of results.


Can Your Hair Really Grow Faster in a Week with Rosemary Oil?

If you want to know how to make your locks grow faster in a week using rosemary oil, here’s the bottom line.

Your hair will probably grow faster than normal but not necessarily enough to be visible to your eye. 

Most people’s hair grows about ⅛ an inch a week which we don’t even see. Rosemary oil may make it grow longer and faster, but you probably won’t see results with the naked eye for a month or two.

Things to Know When Using Rosemary Oil for Hair

Now that you know of different ways to use rosemary oil for hair, here are some additional expert tips for the best results!


How Often Should I Apply Rosemary Oil to My Hair?

How often you apply rosemary oil to your scalp will depend on how oily your hair gets and how often you wash your hair.

If you wash your hair every day, you could probably use rosemary oil 2-3 times a week. But if you’re only washing your hair once a week as it is, it might be best to give your hair a break and only use rosemary oil once a fortnight.

Or, if you find your hair gets oily very often, use it as an occasional treatment to avoid clogging your scalp up.


Can I Leave Rosemary Oil in my Hair Overnight?

When you want to maximise your results, you might be tempted to let the rosemary oil stay in your hair overnight.

But it’s not necessarily the best ideaRosemary oil can be quite irritating to the scalp, and leaving it on overnight can lead to irritation and itchiness. 

Leaving any oil on your scalp overnight is also a risk for clogging the pores of your scalp and developing pimples – either in your hair or around the edges of your face.

And finally, you really don’t want to go to sleep with damp hair – oil or otherwise. It can cause a damp, dark environment that encourages mould and fungus to grow. Enough said!

So if you want to boost your hair growth in 2024, you should definitely give rosemary oil a try! And when your luscious locks are ready, Wecasa can bring a hairdresser to you to give you a new hairstyle.
