Can Rosemary oil treat hair fall and hair loss?

The belief that Rosemary oil encourages hair regrowth may come to light owing to the general health benefits of Rosemary. This plant boasts of having anti-inflammatory properties, improving blood circulation, and promoting nerve growth.

Similar to peppermint or castor oil (both known to promote hair regrowth), Rosemary oil also strengthens blood circulation in your scalp. This, in turn, provides sufficient blood supply to the hair follicles preventing hair damage and loss. Rosemary oil can also prevent dry, itchy scalp, dandruff, and premature graying.

Can I directly apply Rosemary oil to my hair?


Essential oils in their pure and raw form are very concentrated. They may quickly irritate your hair scalp. So it is advisable to opt for the mix n match method, a.k.a. DIY.

The hair experts recommend that you first dilute the Rosemary oil by using a carrier oil, like coconut oil, pumpkin seed oil, or grapeseed oil. Conversely, you can use other products, like shampoo, rather than applying the oil directly to your scalp and hair.

DIY Rosemary oil and carrier oil -

As per the Trichologists, use this thumb rule when diluting the Rosemary oil - pour fifteen drops of Rosemary oil with six teaspoons of your choice of carrier oil (coconut oil, olive oil, jojoba oil, argan oil, etc.). Mix it in a bowl, then apply it to your scalp and hair and massage it. Leave the oil for at least ten minutes and wash it out.

DIY Rosemary oil and shampoo -

If you want to mix the oil with your shampoo, our Trichologists advise adding a couple of drops of the Rosemary oil to an almond-sized amount of your shampoo. Pour it on your hair and massage for at least five minutes before washing.

iv. You can also make a Rosemary oil solution at home - simply dilute your Rosemary oil by mixing a couple of drops with a carrier oil. Apply it to your scalp and leave it overnight.

v. You can also make a Rosemary concentrate at home - add a handful (or two) of dried Rosemary leaves to a quarter of boiled distilled water. Allow this mixture to steep for a minimum of five hours. Longer the steeping time, the higher the concentrations. You can use this mixture either by fusing it in your shampoo (take thee times the amount of shampoo than the concentration) or by applying a few drops directly to your scalp. Make sure the mixture is at room temperature before you use it. Also, do a test patch to determine any reaction or sensitivity.

Can I use Rosemary oil for hair every day - is it safe?


If you want to use Rosemary oil for hair on a regular basis, make sure you dilute the oil by mixing it with a carrier oil - it is an easy DIY process but a mandatory one. Make sure to wash your hair frequently so that the oil mixture does not clog your hair follicles. You can also (alternatively) use a Rosemary oil serum to treat your scalp.

Trichologists believe the quality that makes Rosemary oil for hair stand out from other such carrier oils is its hair health benefits. Meaning - it promotes blood circulation to your dry, itchy scalp, thus, strengthening your overall hair and preventing further hair loss. While other oils merely talk about hair regrowth.

Also, Rosemary oil is slightly more concentrated than other essential and carrier oils. So, you must use it wisely, or it may cause irritation in your hair or skin.

What are the health benefits of Rosemary oil for hair?


1. Rosemary is a popular medicinal plant that has been useful (for ages) to treat many ailments, including hair loss and skin irritation.

2. It has powerful anti-inflammatory properties that help in promoting skin and scalp health.

3. Vasoconstriction and Vasodilation properties: Rosemary oil improves blood circulation and acts as a vasodilator. It means that it can open and dilate the blood vessels to encourage the blood to flow easily through the veins. This, in turn, provides a number of health benefits to both the scalp and hair strands.

4. Regular application of Rosemary oil aids in promoting hair growth (not yet scientifically proven, though)

5. Strengthens hair: Rosemary oil tends to protect your hair from breakage and damage, therefore reducing further hair loss. With proper and regular usage, your hair may start appearing thicker, stronger, fuller, and shinier.

6. Alleviates irritating scalp: One of the key ingredients in Rosemary oil is carnosic acid, which is known for its skin and tissue restorative quality. This can improve scalp itchiness, irritation, and overall scalp health.

7. Preventing loss of hair: The quality of Rosemary oil to prevent hair loss comes into the picture owing to its improvement of the scalp and prevention of hair breakage by regulating proper blood flow.

8. Heals dry scalp and eliminates dandruff: Rosemary oil can reduce dandruff and dry scalp-related problems by acting as an anti-fungal and anti-bacterial agent. This, in turn, also leads to improved hair growth if the hair damage was a result of any bacterial or fungal issue.



For decades, Rosemary oil has been known for its medicinal and culinary properties. However, recent studies say that using Rosemary oil for hair can help promote hair regrowth.

Science and several peoples' experiences together suggest that any essential oil (for that matter) does not fully protect against hair loss, especially if it is female or male hereditary baldness. Having said that, Rosemary oil is in itself a simple remedy that you can easily use at home with no dangerous side effects known. Conversely, it is actually quite safe when you use it correctly and DOES enhance the overall texture of your hair.
