Rosemary oil for hair growth, does it live up to the hype?

Updated: May 16, 2023

Whilst it’s more commonly associated with a classic Sunday roast, surprisingly, Rosemary has also been linked with endless health and beauty benefits. It is suggested that this little bottle of magic has been known to delay the onset of premature grey hairs and improve circulation. According to popular opinion, it’s the miracle that you never knew you needed.

Intrigued? You should be!

Guys and gals, this stuff is a game-changer!

First up, what is it?

Rosemary essential oil is made from the rosemary shrub or Rosmarinus officinalis L. (if we’re being fancy). It’s usually found growing in Mediterranean countries with Spain and Tunisia being the largest producers of this wonder herb. Rosemary oil is commonly used in the beauty industry, particularly in aromatherapy, hair and skin products. Prized for its antifungal, antimicrobial and antioxidant properties (removes gunk to you and me) this potent product packs a punch when it comes to flare-ups and irritation.

Whilst most things on Tik Tok and Insta are super hyped up with minimal supporting evidence (such as hair growth gummies) this little beauty hack deserves some serious credit.

Show me the Science!

Rosemary oil is believed to stimulate the scalp and help promote hair growth. It helps to increase blood circulation to the scalp, which in turn helps to nourish the hair follicles and encourages new hair growth.

According to leading MD, FAAD board-certified dermatologist Marnie Nussbaam;

“The rosemary plant contains carnosic acid, which is known to heal nerve damage, tissue damage and improve cellular turnover, therefore, it encourages nerve growth and improves blood circulation. The reason blood circulation is so important to hair growth is that without a proper blood supply, the follicles do not get the nutrients they need to grow the hair, and they can die off.”

If we’re being honest, the options for non-surgical hair loss treatments are pitiful. Is this the much-needed revolution? Apparently so. In a 2015 study, Rosemary oil was tested against minoxidil (a drug-based treatment used in products like Regaine) in a clinical study. The study concluded that Rosemary oil was just as effective as minoxidil after just six months of continued use. What’s more, the study suggests that negative side effects were significantly less prevalent when using Rosemary oil as opposed to its chemical counterpart. Some side effects that commonly occur when using minoxidil are skin irritation, dryness, itchiness and in more extreme cases, palpitations.

I’ll pass on those thanks.


If re-growing hair whilst swerving side effects wasn't impressive enough, it’s been demonstrated that Rosemary oil also:

Reduces Dandruff: Rosemary oil has antifungal properties that can help reduce dandruff and other scalp issues, in addition to helping combat scalp infections and break the cycle of scalp irritation.

Protects Hair: Rosemary oil helps to protect the hair from environmental damage caused by free radicals in addition to keeping the hair well-nourished, which helps to reduce breakage.

Improves the Scalp: Rosemary oil helps to improve the scalp's overall health by reducing inflammation and relieving itchy and flaky scalps. This little wonder also helps to combat bacteria and fungi that can lead to scalp conditions such as psoriasis and eczema.

If you’re looking to improve the fullness of your hair, you might be questioning how long you need to wait until you see a transformation. In short, everybody will see results at a different rate. Rome wasn’t built in a day, right? Based on current studies, it’s suggested that continued use over a minimum six-month period is best. If you're looking for longer, more luscious locks then stick with it for as long as required.


How do I use it?

  • Add a few drops of it to a carrier oil like coconut or jojoba oil ( it’s important to dilute the potency of the rosemary oil to prevent irritation.)

  • Massage into the scalp to increase the blood flow and stimulate the scalp.

  • Leave on for up to thirty minutes

  • Shampoo and condition the hair as normal.

  • Repeat up to twice weekly.

Is it for any hair type?

Good news! Rosemary oil does not discriminate, it's suitable for all hair and scalp types. If you have naturally oily hair, you may find that you need to repeat the cleansing step to ensure all traces of the carrier oil are removed as these can tend to be a little heavy on the hair.

I’m in, any recommendations?

There are endless Rosemary oil options on the market but here are my personal favourites based on quality and performance.

Centred En-Root Scalp Oil

My ultimate go-to is En-root Scalp oil from Centred. According to Kieron Tudor (Co-Founder of Centred)

“You can use En Root Scalp Oil without any residue thanks to its unique formula specifically designed to emulsify when rinsed with water which allows the oil to transform from an oil into milk and be rinsed free from the hair leaving no residue”

This beautiful oil not only smells incredible; the nourishing formula is super gentle yet incredibly effective and the no-fuss nozzle makes application ridiculously easy. This one’s a keeper!

It’s free from synthetic fragrances, colours and preservatives as well as mineral oil-based raw materials and is vegan friendly. Weleda's oil is slightly kinder to the pocket than the oil from Centred and is a great starter oil to begin your hair revamp journey.
