If you are interested in the best ways to use diluted rosemary oil for hair growth, you are likely one of the 85% of men or 55% [1][2] of women to experience hair loss during their lifetime. Fortunately, you are on the right track, since rosemary oil has been proven to be one of the best essential oils for hair growth.

Several studies have shown that diluted rosemary oil (rosmarinus officinalis leaf oil) is quite effective in reducing hair thinning produced by androgenetic alopecia, with results comparable to those of popular hair growth drug Minoxidil [3]. At the same time, there is early research that indicates it may also play a role in restoring alopecia areata hair loss when combined with other oils.

What is diluted rosemary oil?

The flavourful rosemary plant found in most kitchens is not only delicious when cooked, but it can also help stimulate your hair growth. The essential oil extracted from it is a natural DHT blocker, which makes it effective in reducing hair loss associated with male pattern baldness and increasing hair density, making hair thicker.

  • Oxygenated monoterpenes (44%)
  • Monoterpenes (28%)
  • Camphor (23.9-35.8%)

Why does rosemary oil need to be diluted?

Like most essential oils, pure rosemary essential oil should not be used on your skin in its natural concentration, because it can lead to unwanted side effects [4], such as:

That is why it is recommended to dilute it in a carrier oil, such as jojoba oil, coconut oil or grapeseed oil before applying it to your scalp and hair.

Is diluted rosemary oil good for hair growth?

Diluted rosemary oils are some of the most effective essential oils for hair growth, with scientifically proven results against male pattern baldness.

One study performed in 2015 on 100 men with androgenetic alopecia revealed that patients treated with a diluted rosemary oil treatment experienced a similar increase in hair count as those treated with Minoxidil 2% (one of the most prescribed hair growth medications), both after 3 and after 6 months of clinical trial [3].

One small study also found evidence that when mixed with lavender oil, cedarwood oil, thyme oil and coconut oil, it can reduce hair loss by 44% in alopecia areata [8].

How do you use diluted rosemary oil for hair growth?

The easiest way to use diluted rosemary oil for hair growth is to apply a few drops on your scalp and gently massage it in. You can also use a wide-toothed comb to spread it on the entire length of your strands, so you can get its moisturising and conditioning benefits. Feel free to leave it in for as long as it feels comfortable to you before washing your hair.

For enhanced hair benefits, you can also mix your diluted rosemary oil with a multitude of other essential oils, such as lavender, peppermint, tea tree, thyme, or lemongrass and use the mixture as a hair mask.

How long can you leave diluted rosemary oil in your hair?

There is no specific time limit for how long you should leave diluted rosemary oil in your hair, as it is generally safe and well tolerated. You can leave it on for 30 minutes, overnight or even for the entire day, as long as you are not experiencing sensitivity to it or an allergic reaction.

If you find that your scalp gets itchy or irritated from leaving the diluted rosemary oil on your hair, simply reduce the amount of time you leave it on to a comfortable duration.

However, please be aware that while diluted rosemary oil is safe and has multiple hair benefits, it is still an oil, which means it can build up on your scalp and cause greasiness unless you wash your hair regularly.

Should I mix rosemary oil with water for hair growth

Should I mix rosemary oil with water for hair growth?

Oil does not mix well with water, so while some websites endorse diluting rosemary oil with plain water, it is generally not recommended. Using carrier oils does not only work better to dilute your essential oils, but it can also provide additional moisturising, conditioning, antioxidant and nutritional benefits for your hair and scalp, depending on the blend you choose.

Alternatives to diluted rosemary oil for hair growth

While rosemary oil can have good results for hair growth in some people, it may not necessarily work for you. If that happens, you might want to try one of the following scientifically proven hair growth treatments (please see a trichologist for a safe and effective recommendation for your specific condition):

  • Finasteride – the most prescribed medication for the treatment of male pattern baldness. It efficiently inhibits excessive DHT production, limiting follicle miniaturisation and hair loss (not recommended for premenopausal women).
  • Minoxidil – usually applied topically, Minoxidil dilates the blood vessels in your scalp, allowing for better blood flow and thus, helping more nutrients to reach your hair follicles.
  • Steroid creams – whether you are experiencing alopecia areata or a common scalp problem such as scalp psoriasis, applying topical steroids can help reduce inflammation and hair loss.
  • Derma rolling for hair growth – also known as microneedling, this therapy involves creating very small puncture wounds in your scalp which trigger a healing response that can help with hair growth. Furthermore, the punctures also help topical medication penetrate your scalp, increasing their effectiveness.
  • Low-level light therapy for hair loss – this therapy uses low-powered lasers to focus a specific frequency of light onto your scalp, which stimulates cell metabolism and blood flow, promoting hair growth.
  • Hair transplant – effective, natural-looking and permanent hair restoration can be achieved by harvesting hair follicles from some healthy areas of your scalp and reimplanting them in balding ones.

Are you concerned about hair loss?

If you are worried you may be experiencing hair loss, it is best to book a consultation with a trichologist for the first signs of hair thinning and balding. They can provide you with a timely and accurate diagnosis and recommend the best treatment for your particular hair and scalp condition.

Since some types of alopecia can progress if left untreated, waiting too long to see a specialist can render hair growth medication and therapies ineffective on their own. If that happens, your best chance at recovering your once luxurious locks may be a hair transplant.

However, if it turns out that hair restoration surgery is the best solution for you, there is no need to worry. More and more people, including many celebrities, are getting hair transplants nowadays, with great results. That is because the procedure is simple, fast and effective and the best hair transplant clinics have a 97-100% success rate, regardless of whether you opt for an FUE or FUT type surgery.  Moreover, a hair transplant is permanent, so it is an investment you make in your appearance for years to come.

If you have any doubts about whether it is possible to get a natural-looking hair transplant, all you have to do is take a look at our before and after hair transplant gallery.
