Given its increasingly viral status, rosemary oil for hair growth has become somewhat synonymous with thick, shiny hair and healthy re-growth. So, if you've been wanting to try it out yourself to see if the rave reviews live up to expectations, now's your chance to do so at a dramatically reduced price, all thanks to Amazon Prime Day.
We've spotted the bestselling Nature Spell Rosemary Oil For Hair & Skin is discounted by 35% right now, bringing the overall price down to just £6.50. So when we say: run, don't walk – we mean it. Yet the question still stands: does rosemary oil for hair growth actually work?
Let’s start with the basics: rosemary (known officially as rosmarinus officinalis) is a herb native to the Mediterranean region, and its oil, which is pale in colour and has a woody aroma, is also widely used in aromatherapy and various skincare products – as well as haircare.
Having amassed well over 500 million views (and counting) on TikTok, the impressive ‘before and after’ videos tagged with #rosemaryhairgrowthoil are certainly hard to ignore, especially since some showcase just how effective rosemary oil can be when it comes to hair loss – something that, according to the NHS, 8 million women experience in the UK.

But considering how many different oils are used in haircare products – including jojoba oil, castor oil, almond oil, coconut oil, argan oil and various seed oils – what makes rosemary oil so special, you ask? While research is limited, “studies have demonstrated that rosemary oil can indeed stimulate hair growth by improving blood circulation to the scalp and promoting the proliferation of hair follicle cells,” says Dr Nick Fisherman, trichologist at Watermans Hair.

To delve deeper, we’ve asked several experts to shed light on everything there is to know about rosemary oil, its benefits and advice on how to use it to achieve the best results. We've also put together a few tried-and-true recommendations for you to consider adding to your haircare routine. Read on and enjoy.
What are the benefits of rosemary oil for hair?
Improves hair growthOne 2015 study comparing rosemary oil to minoxidil (a popular active ingredient in topical hair regrowth treatments) found that after six months both groups had similar results with a significant increase in hair growth. “Although this study suggested it may be beneficial, there is currently a lack of clinical evidence to recommend rosemary oil as a hair loss treatment,” notes Zoë Passam, consultant trichologist at Philip Kingsley.
Soothes scalp irritation“The oil has also been found to possess anti-inflammatory properties, which can help soothe the scalp and reduce irritation and itching,” adds Fisherman. Essentially, when used as a scalp treatment, rosemary essential oil can help create a healthy environment for optimum hair growth. Oh, and in the same study mentioned above, the group using rosemary oil reported less itchiness than those using minoxidil.
May help prevent dandruff“Rosemary oil can also help to restore the scalp's microbiome balance due to its antimicrobial properties,” explains Dr Bhavjit Kaur, medical aesthetic practitioner. “Since dandruff usually occurs due to an excess of skin fungus (malassezia), the antimicrobial properties of rosemary may help.”

How long does it take to see results?
The science suggests that it may work but as with anything there is a catch, rosemary oil needs to be applied in the right quantities, over a long period of time to see results. “There is limited evidence for rosemary oil as a hair loss treatment, but seeing results from any hair loss treatment takes time, due to the average rate of hair growth, typically 1-1.5cm per month,” says Passam. The experts agree that it takes six months (at least) to see results.
It's also important to note that hair growth can also be influenced by a variety of factors, including genetics, nutrition, stress, and hormonal changes, and the use of rosemary oil alone is unlikely to be the panacea for all hair growth.
Why the Indian ritual of hair oiling could be the secret to better hair Gallery7 PhotosHow can I use rosemary oil for hair?
According to Fisherman, “when applying rosemary oil to your hair and scalp, it's important to dilute it with a carrier oil such as jojoba, coconut, or olive oil. This helps to prevent skin irritation and ensures that the oil is evenly distributed throughout your hair." Then leave the oil on your hair for at least 30 minutes before rinsing it off with shampoo and water. “Because rosemary oil can cause skin irritation, avoid using on inflamed or broken skin,” adds Passam.

After applying diluted rosemary oil, Viviscal Ambassador and trichologist Hannah Gaboardi recommends using a scalp massager. "Scalp massaging increases hair thickness by stretching the cells of hair follicles. This then stimulates the follicles to produce thicker hair. So using it in conjunction with rosemary oil would be very effective’’.
Hair Oil Root Comb ApplicatorGrow Gorgeous Scalp Massage Tool“Using rosemary oil directly on your hair strands can provide additional benefits such as improving hair texture, reducing split ends, and enhancing shine. To apply rosemary oil directly to your hair strands, you can add a few drops of the oil to your regular shampoo or conditioner, or create a hair mask by mixing the oil with a carrier oil and leaving it on for 20-30 minutes before rinsing. However, it's important to note that using too much rosemary oil directly on your hair can lead to dryness and irritation, so be sure to use it in moderation and dilute it properly with a carrier oil,” Fisherman warns.
Can rosemary oil help with hair loss caused by alopecia?
Alopecia is a medical condition that can cause hair loss and baldness that can affect any body part – there is no known cure for it yet, though there are experts who can help. Rosemary oil has been reported to help with hair loss caused by alopecia, but only anecdotally, since rosemary oil stimulates hair follicles and improves circulation to the scalp. Fisherman believes that rosemary oil alone is not the cure for alopecia, and it may not be the most effective hair treatment. However he adds: “incorporating rosemary oil into your hair care routine may still have beneficial effects on hair health and growth, and it may be worth discussing with a healthcare provider or board-certified dermatologist as part of a comprehensive treatment plan.”
What are the side effects of using rosemary oil for hair?
Rosemary oil is known to have little-to-no side effects and is safe for all hair types, including coloured hair. “Like other essential oils, however, pure rosemary oil has active components and can result in scalp irritation,” flags Kaur. This is why it should always be diluted with a carrier oil. Also, it's a good idea to do a patch test with several drops of rosemary oil before applying it more liberally – “if there is irritation, stop using it immediately.”
