The essential oil rosemary – which gets its name from the powerful concentrated plant essence it contains – has various nutrients that could offer many benefits to the scalp and hair. It’s sourced from the leaves, stalks, flowers, and flowering tops of the rosemary plant.

The oil can enhance the shine of hair strands. But beyond this, a study published in the Scientific African Journal states that rosemary is a medicinal plant known for its potential to promote hair growth. 

In this article, we’ll explore how rosemary oil can be used for hair growth. We’ll also look at its additional benefits for hair and another solution you can use alongside it.

What is Rosemary Oil & What Does it Contain?

The essential oil pure rosemary is obtained from the Rosmarinus officinalis. This belongs to the mint plant family, and its oils have been applied to hair for more than 100 years. 

Thiamine (vitamin B1), folate (vitamin B9), pyridoxine (vitamin B6), and vitamins A and C are just a few of the components of rosemary oil.

This aromatic oil also contains calcium, magnesium, carnosic acid, and rosmarinic acid. Antioxidants, vitamins, minerals, and elements such as these are known for their anti-inflammatory and anti-microbial effects on the scalp.

Yet researchers have suggested that rosemary oil and its components have plenty of additional benefits for scalp care. A study published by the University of Campinas found that rosemary oil inhibited fungal growth by 86%. Research published in the International Journal of Trichology also states that rosemary oil protects hair strands from oxidative stress.

How Does Rosemary Oil Work?

Strengthening the hair follicle and stimulating blood flow are two ways rosemary oil might work well for hair growth. Increased blood circulation or blood supply and nutrients from the roots might mean the follicles deliver the important elements for hair to thrive despite hair loss.

It’s suggested that consistency is key when using rosemary oil for hair growth. This essential oil can potentially work well after six months of use.

Advantages of Rosemary Oil for Hair

To get rid of frizz and replenish each strand’s healthy condition, this oil might help. Additionally, the following benefits could apply to hair when rosemary oil is applied:

  • Dandruff Control – Minimises dry, itchy scalp and can soothe the skin near the roots by lessening dandruff flakes.
  • Blood Flow to the Scalp – Increases blood flow and blood supply to the scalp and follicles, potentially prompting hair growth.
  • Premature Greying and Growth – Some individuals use rosemary oil as a means to prevent premature greying—some studies, such as research published in the Cureus Journal suggest that the oil can delay grey hair onset and lead to enhanced hair growth (by 46.71% on Day 90).
  • Clear Follicles – With anti-microbial elements, rosemary oil may help clear away any bacteria present on the scalp or in the follicles.
  • Moisturises and Invigorates the Hair – With nutrients such as vitamins A, B, and C, rosemary oil can moisturise and invigorate the dry and damaged hair.

Key Ways to Use Rosemary Oil to Achieve Top Hair Benefits

Carrier oil mixtures and applying the oil to the scalp are two ways to use rosemary oil for hair growth. We’ve explained these methods and more below:

  • Carrier Oil Mixtures – Five drops of rosemary oil incorporated into a carrier oil such as coconut oil or sweet almond oil can be the ideal mixture to apply to your scalp. Leave the mixture in the hair for 10 minutes before washing it out.
  • Apply the Oil to the Scalp & Massage – Massaging the rosemary oil once you have applied it can ensure the follicles get the benefits of the oil. Use a circular massaging motion and leave it for 30 minutes in total.
  • Add the Oil to Shampoo – Five drops of rosemary oil added to your shampoo create a nourishing solution. Use it to wash your hair each day, but take care not to add excessive amounts of oil to the shampoo, as this can over-concentrate the solution.
  • Add the Oil to Styling Products – Include five drops in each ounce of styling product, such as heat defence sprays or hair creams, and apply the solution as usual.

Top Tips for Selecting Rosemary Oil

With so many rosemary oil products available, it’s not always easy to narrow your choices down. Our professionals have a few tips (see below) to help you select the right rosemary oil product for your hair:

  • Stick to 100% Pure Rosemary Oil – Look for the essential oil of rosemary instead of rosemary extract or diluted rosemary, and avoid options that contain artificial chemicals. The purest options will likely have a better effect.
  • Have a Look at the Ingredients – Prioritise rosemary oil that is free from scalp-irritating preservatives or additives to ensure your scalp gains the benefits of pure ingredients.
  • Consider the Extraction Process – Pick rosemary oil products that have been steam-distilled or cold pressed—these options retain a greater amount of their beneficial properties than those oils that undergo a heat extraction process.
  • Think About Ease of Use – Ease of use is important, making it simpler to apply the oil in your preferred approach. You may want to select a bottle with a pipette to add a few drops to the carrier oil, or you may prefer a large, pre-mixed hair treatment that helps you apply the oil straight to the scalp.
  • Look into the Carrier Oil Compatibility – Consider if you would like to add the rosemary oil to a carrier oil and check whether it is compatible with options such as jojoba oil or argan oil.

How Beneficial is Rosemary Oil for Healthy Hair Growth?

Rosemary hair oil, according to a Skinmed study published in 2015, can be beneficial for hair growth. It led to an increase in hair count after six months of use during the study. Additionally, other studies, such as the more recent 2022 study cited in the introduction, suggest that solutions that contain 10% rosemary oil can encourage hair growth in animals.

Since rosemary oil also contains antioxidants that keep the follicles free from oxidative stress or damage, it could help prevent additional damage and minimise hair thinning. But more research is needed to support these findings, especially in humans.
