Rosemary Oil: The Natural Solution for Hair Growth and Health

Rosemary is well-known for its incredible flavor and aroma, but did you know it’s also good for your hair and skin? Rosemary oil extracted from the herb has been used for its cosmetic and health-promoting effects for centuries. Whether you’re dealing with hair loss, dryness, or just looking for a way to improve the appearance and texture of your tresses, rosemary oil may be just the solution you need.

Rosemary Oil is Good for Hair Growth

Rosemary oil’s effects on hair can include a remarkable ability to help it grow better and slow hair loss. The oil contains compounds that have been shown to increase blood circulation to your scalp, which in turn helps to promote hair growth. 

Rosemary oil blocks the effects of dihydrotestosterone (DHT) — a hormone implicated in baldness. DHT is essential for male health but has the side effect of causing hair loss in genetically susceptible people. By inhibiting its effects only on your scalp, rosemary may help slow male pattern hair loss without the negative side effects associated with finasteride and other DHT blockers.

Rosemary Oil Supports Scalp Health

Another benefit of rosemary essential oil is its ability to improve the health of your scalp. The oil has anti-inflammatory properties that can help soothe an itchy or irritated scalp, as well as reduce dandruff and improve the management of other conditions. 

Rosemary oil is a natural astringent that can help tighten your scalp skin and reduce excess oil production. These effects can help prevent your scalp or hair from feeling greasy and make your hair easier to style.

Rosemary Oil Soothes Dry Hair

Oil from the rosemary plant is thick and highly moisturizing, making it an ideal ingredient for dry or brittle hair. The oil can help hydrate your hair and reduce breakages, ensuring it stays strong and healthy as it grows. This hydrating ability is similar to argan oil — another popular haircare product.

Get More Manageable Hair With Rosemary

One of rosemary oil’s unique effects on hair is its ability to add extra volume and body. In contrast, castor oil and other moisturizers typically make your hair look smoother but may flatten it.

The oil can help to plump up your hair strands and add lift, allowing you to achieve a wider variety of style with ease. Additionally, rosemary oil’s fresh, woody scent can help leave your finished look smelling nice.

How Should You Use Rosemary Oil in Your Haircare Routine?

To use rosemary oil, consider adding a few drops to your shampoo, conditioner, or other hair products. You can also massage the oil directly into the scalp, but you’ll need to dilute it into a carrier oil, such as olive oil, first, as pure essential oils can be irritating. For best results, massage into your scalp in a circular motion and allow the oil to sit on your hair and scalp for at least 30 minutes before washing it out.

Rosemary is a potent ingredient, so it should be used cautiously on sensitive skin and avoided during pregnancy. Use it sparingly until you know how your hair and skin react to it.

Is Rosemary Oil Dangerous?

Rosemary oil is generally considered safe for haircare when used as directed. However, like any essential oil, it’s important to dilute it before applying it to your scalp to minimize the risk of skin irritation or other adverse reactions. 

It’s also essential to be mindful of the other ingredients in your haircare products, as some may interact with rosemary and increase the risk of skin irritation. Avoid pairing rosemary oil with drying ingredients such as alcohol for this reason.

If you have sensitive skin or are prone to allergies, it’s a good idea to perform a patch test on a small area before using rosemary essential oil more widely. If you experience any adverse reactions, such as skin irritation, redness, or itching, discontinue use.

How Often Should You Use Rosemary Oil?

It’s best to base how often you use rosemary oil on your individual needs and desired results. Generally, using it a few times a week is okay. However, some people can use it more frequently without any adverse effects, while others may need to limit their use to ensure their skin remains comfortable. 

To determine the best frequency for you, use the oil once or twice a week and gradually increase it as needed. Be aware of any skin irritation or adverse reactions, and stop using the oil if necessary.

Can You Make Rosemary Oil Yourself?

Yes, it is possible to make rosemary oil yourself. Making essential oils involves steam distillation, which separates the oil from the plant material. This process can be done at home with the right equipment, although it can be time-consuming and requires a certain level of expertise.

To make rosemary oil, you will need fresh rosemary sprigs, a still or distillation apparatus, and a heat source. Place the sprigs in the still with water and heat the mixture to produce steam. As the steam rises, it will carry the essential oil with it, which then condenses back into a liquid afterward. 

Making essential oils at home can be dangerous if proper precautions are not taken, as the process involves handling hot liquids and steam. It can also be difficult to achieve a high-quality essential oil without proper equipment and experience, so it may be better to buy rosemary oil if you’re unfamiliar with the process.

Rosemary Oil vs. Rogaine: Which One is Better for Your Hair?

When it comes to hair health and growth, rosemary oil and Rogaine are two popular options for treating hair loss or male pattern baldness. 

Rosemary oil is made from the rosemary plant and is used on the scalp to provide nourishment and boost hair health. It can improve blood flow to your scalp and block DHT, which can help improve hair growth.

Rogaine, on the other hand, is a prescription medicine containing minoxidil. When applied to your scalp, it helps promote hair growth by shortening your hair’s resting phase and encouraging it to remain in its growth phase.

So, which one is best for you? It depends on your individual hair goals and health. If you’re looking for a natural way to improve hair growth, rosemary oil may be a good choice. But if you’re experiencing significant hair loss, Rogaine may be more effective. 

See a doctor or hair loss specialist first for evaluation, as some causes of hair loss are easily reversible with proper treatment. These conditions typically require professional diagnosis and prescription medications for treatment.

Can You Use Rosemary Oil for Beard Growth?

Just as rosemary can be used for hair growth, it may also work well for beard growth. Rosemary oil’s effects on hair follicles should work exactly the same whether applied to the follicles on your scalp or chin and jawline. It’s also rich in antioxidants and other nourishing compounds that can help improve your beard’s condition and prevent the hair from becoming dry, brittle, and prone to breakage.

To use rosemary essential oil for beard growth, mix a few drops with carrier oil, such as coconut oil or jojoba oil, and massage the mixture into your beard. Leave the oil on for at least 30 minutes, or overnight, before washing it off with a gentle beard shampoo. You can repeat this process a few times a week for the best results.

It’s important to note that not everyone’s beard will respond the same way to rosemary oil. However, for many people, using rosemary oil can help promote beard growth and improve beard health.

Can Rosemary Oil Ease an Itchy Scalp?

Rosemary essential oil may be able to ease an itchy scalp. Because of its anti-inflammatory and antiseptic properties, it may help soothe an itchy scalp and reduce the symptoms of scalp conditions, such as dandruff and psoriasis.

Is Rosemary Oil Good for Low-Porosity Hair?

Low-porosity hair has cuticles that lay flat, making it difficult for moisture to penetrate the hair shaft. This can result in dry and brittle hair that is prone to breakage.

Rosemary oil is a light and non-greasy oil that can help nourish and hydrate low-porosity hair without weighing it down. The oil contains antioxidants and other beneficial compounds that can help ensure your hair feels soft and smooth.


Rosemary oil can give your hair the TLC it deserves. From reducing an itchy scalp to promoting hair growth, there are so many reasons to consider incorporating it into your haircare routine. Whether you use it as a leave-in treatment, add it to your shampoo or conditioner, or mix it with carrier oil, there are plenty of ways to make rosemary oil work for you. So, why not try it and see the difference it can make for your hair?
