If you’re a regular TikTok scroller, chances are your FYP has been full of people waxing lyrical about a miracle product - rosemary oil. If you haven’t, don’t worry. We’re here to give you all the info. Heralded for its hair growth super powers, even for those who have suffered from hair loss, it’s also said to be a scalp care hero.

Now, we don’t want to make any heavy claims about the life-changing effects of rosemary oil, but we are going to go through exactly what it is, its benefits and how to make it yourself. Let’s go! 

What is Rosemary Oil?

As we mentioned, rosemary oil is having its turn in the spotlight thanks to TikTok. But what is it and what is it used for? Rosemary oil is an essential oil extracted from the leaves of the rosemary plant, a woody herb native to the Mediterranean region. To make the oil, the fresh leaves of the plant are typically steam-distilled (but we’ll tell you how to make it at home yourself later) and then the evaporating oil is collected. 

With its strong, herbal scent, rosemary oil is commonly used for aromatherapy and in beauty products. It’s also used in traditional medicine for muscle pain, headaches and even respiratory issues. Most recently, it’s gained popularity in the haircare world as it’s believed to stimulate hair growth and improve scalp health. Sounds like it does it all!

The Benefits of Rosemary Oil for Hair

Now you know a little bit about the wonder oil, we’re going to go into its benefits, but first, a little disclaimer. There is some scientific evidence to support the following benefits of rosemary oil and while these findings are super promising, larger and more rigorous studies are needed to confirm them. Serious stuff over, onto the benefits. 

Its main claim to fame is that it's believed to promote hair growth and thickness by stimulating blood circulation in the scalp and it encourages the delivery of nutrients to the hair follicles. Lovely stuff. This can also help to reduce hair loss and dandruff, since the scalp becomes healthier and better nourished from all that blood flow.

Not only that, rosemary oil is said to potentially reduce the appearance of grey hairs, as it has an effect on the pigmentation of hair. Now, we’re not saying that there’s anything wrong with grey hairs - if you’ve got them, we’re all for flaunting them but if you’d rather disguise them, rosemary oil could do the trick. This one might need a bit more research though. As with any essential oil, use it with caution and consult a healthcare professional before using it to treat any serious health conditions. 

How to Make Rosemary Oil for Hair

Want to make your own rosemary oil at home? It’s pretty simple, just follow this easy step-by-step guide: 

You will need: 

  • Fresh rosemary leaves 
  • A carrier oil such as olive oil or coconut oil 
  • A glass jar with a lid 
  • Cheesecloth or a fine-mesh strainer 
  • A funnel 


  1. Start by washing and drying the rosemary leaves to remove any dirt.
  2. Finally chop the leaves, or crush them with a mortar and pestle, to release their essential oils.
  3. Fill the glass jar with the carrier oil. Make sure you leave a bit of space at the top! 
  4. Add the rosemary leaves to the jar and stir to combine. 
  5. Seal the jar tightly with the lid and place it in a cool, dark place, such as a cupboard. 
  6. Leave the mixture to infuse for at least a week, shaking the jar occasionally to distribute the oils. 
  7. After a week, strain the oil through cheesecloth or a fine-mesh strainer into a clean jar or bottle. A funnel makes this part easier! 
  8. And voila! Store the rosemary oil in a cool, dark place until it’s ready to use. 

To use the rosemary oil, you can either massage a small amount into your scalp and hair, focussing on the roots, leaving the oil in for at least 30 minutes or overnight, then shampoo and condition as usual, or add it to your shampoo and conditioner to give them an extra boost. For best results, apply it once or twice a week consistently.
