rosemary for hairYou’ve got good instincts for wanting to try rosemary oil for your hair. With over 600 million views on TikTok, this natural remedy is gaining major traction. But before you get swept up in social media hype, let’s take an objective look at the science.

As a board-certified dermatologist passionate about solving hair loss and growth challenges, I’ve extensively researched botanical extracts like rosemary.

Rosemary oil can indeed nourish your scalp and follicles when used properly. By increasing circulation, reducing inflammation, and removing follicle-clogging buildup, rosemary may support stronger, faster hair growth for some.

For best results, incorporate rosemary oil into a comprehensive hair care plan that can be customized just for you. Together, we’ll get to the root of what your hair needs to look its healthiest and fullest.

Key Takeaways

  • Rosemary oil can help stimulate hair growth and circulation when massaged into the scalp or added to shampoo.
  • Making homemade rosemary water or shampoo allows for the natural hydration and cleansing of hair follicles.
  • While rosemary may offer benefits, its effects can vary based on genetics, hair health, and preparation methods.
  • It is important to keep realistic expectations when using rosemary, as there are no quick fixes for hair loss.

What is Rosemary Water?

What is Rosemary Water
You’ve heard of steeping rosemary leaves in water, but are unsure if this DIY hair rinse really works. Rosemary water is made by steeping fresh or dried rosemary leaves in hot water for several hours, then straining out the leaves.

The fragrant, herbal-infused water may seem intuitively beneficial for hair and scalp health, but its true effectiveness is questionable.

The recent TikTok trend has amplified interest in rosemary water, yet scientific research hasn’t confirmed its benefits.

While anecdotal use suggests rosemary water can support hair growth and shine, quality ingredients are key. Sourcing high quality, organic rosemary leaves and using pure, filtered water provides the best chance for hair benefits.

Without oils, rosemary water lacks inherent hydrating qualities, so conditioner may optimize moisturization. Overall, rosemary water’s impacts likely depend on individual hair health and genetics.

Without scientific backing, it’s wise to temper expectations of dramatic results from this DIY hair rinse.

Benefits of Rosemary for Hair

Benefits of Rosemary for Hair
You may have heard that rosemary oil can help promote hair growth and treat issues like dandruff or an itchy scalp. Research indicates rosemary’s circulation-boosting properties may stimulate follicles, while its antiseptic qualities could support scalp health.

The aromatic herb’s anti-inflammatory and antioxidant characteristics may also counteract damage from free radicals and environmental stressors. Some small studies reveal rosemary oil’s potential to increase hair count in people with various degrees of alopecia.

While more research is still needed, adding a few drops of rosemary essential oil to shampoo or massaging diluted oil directly onto the scalp appears unlikely to cause harm and may offer benefits. As with any supplement or essential oil, consult your doctor before use if pregnant, nursing, or being treated for a medical condition.

May Promote Hair Growth

Though some evidence shows rosemary oil may support hair growth, more research is needed to confirm if rosemary water provides the same benefits for your luxurious locks. Rosemary research indicates compounds like carnosic acid may promote healthier hair and scalp.

However, the TikTok trend lacks scientific backing on rosemary water specifically. Treat your tresses with care and love. Consult a trichologist before trying new products, especially if you are experiencing hair loss or scalp issues.

Weigh the potential rosemary benefits against the risks. Focus on your unique hair goals with professional support.

May Improve Scalp Health

While limited, research suggests rosemary oil may help combat scalp itching and dandruff. A gentle scalp massage with rosemary essential oil can increase blood flow to hair follicles, hydrating your scalp while soothing any irritation.

Adding a few drops to your shampoo can help cleanse the scalp, reducing flakiness. Always dilute essential oils and test for sensitivity first. With its anti-inflammatory and antimicrobial properties, rosemary oil shows promise for improving scalp health when utilized properly.

Provides Temporary Shine

Boy, that rosemary oil makes your hair shinier than a freshly waxed car!

  • Improves reflectivity of hair cuticle
  • Contains antioxidants that add luster
  • Hydrates scalp and hair follicle
  • Provides instant, albeit temporary, radiance

Rosemary oil can impart an instant, but fleeting boost in hair shine when applied directly. The hydrating properties provide a temporary glow by smoothing the hair cuticle. However, rosemary does not deeply moisturize hair or have long-lasting effects on shine.

Diluting essential oils and combining them with carrier oils will maximize benefits.

How to Use Rosemary Oil for Hair

How to Use Rosemary Oil for Hair
There are a few simple yet effective ways you can incorporate rosemary oil into your hair care routine. To help stimulate growth and circulation, try massaging rosemary oil directly onto your scalp, mixing it into your regular shampoo, or adding it to homemade shampoo recipes.

You could massage a few drops of rosemary oil into your scalp before washing your hair. Alternatively, add a few drops of the essential oil to your store-bought or homemade shampoo and wash your hair as normal.

For a more concentrated treatment, try making a rosemary oil hair rinse by combining it with water in a spray bottle. Apply the rinse after shampooing, let it sit for 5-10 minutes, then rinse out. Using rosemary oil consistently can help increase blood circulation to the scalp and may stimulate new hair growth over time.

Massage Into Scalp

You can massage some rosemary oil into your scalp and let it sit before washing it out for optimal nourishment. Gently rub a few drops into your scalp for several minutes to boost circulation, which delivers nourishment that may encourage new growth and shine.

Those with sensitive skin should dilute rosemary essential oil with a carrier oil to avoid irritation. Pregnant women should use caution with essential oils or consult their doctor, since safety is not fully established.

Massaging rosemary oil into the scalp before washing may help maximize absorption for improved scalp health.

Mix With Shampoo

Stir a couple drops of rosemary oil into your shampoo before lathering it in your hair. This simple method lets the active compounds, like carnosic acid, penetrate your scalp and follicles. Gently massage the diluted shampoo thoroughly over your head. Allow it to soak for a few minutes before rinsing.

Doing this regularly may stimulate circulation, nourish follicles, and curb thinning.

Add to Homemade Shampoo

Adding rosemary oil to a homemade shampoo is ideal for those wanting natural hydration. Infusing rosemary leaves or rosemary essential oil into your homemade shampoo provides hydrating, nourishing benefits without harsh detergents.

For best results, allow rosemary leaves to steep in the water portion of your shampoo recipe. The rosemary infusion naturally cleanses hair follicles while imparting shine. When using rosemary essential oil, incorporate several drops per ounce of shampoo.

This customizable DIY method enables you to reap rosemary’s hair restorative effects in a simple way.

Rosemary Water Trend on TikTok

While the TikTok trend hypes rosemary water for lustrous locks, the scientific evidence supporting its effectiveness remains cloudy. Do not get swept up in the latest social media hair hack without scrutinizing the facts.

As a dermatologist, I believe knowing your unique hair and scalp needs is key before experimenting with DIY concoctions.

Certainly, natural remedies have their place and rosemary does offer beneficial compounds. However, creating your own rosemary water at home provides no guarantees. The quality and potency depend enormously on the plant material and preparation method.

Store-bought rosemary essential oil gives more consistent dosing than homemade infusions.

Look at your family history and consult a trichologist if hereditary hair loss is suspected. They can provide professional advice tailored to your situation. While some may find rosemary water temporarily boosts shine or soothes a dry, itchy scalp, those with underlying conditions should take caution.

For optimal results, integrate rosemary water with balanced nutrition, low stress, and proper hair care techniques.

Should You Try Rosemary for Hair?

Should You Try Rosemary for Hair
You’ve likely seen rosemary recommended for hair growth and health, especially with its recent popularity on social media.

While some initial research shows promise, clinical evidence for rosemary’s effects on hair is limited. Potential benefits like increased circulation, anti-inflammation, and tissue repair may support hair follicles and stimulate growth.

Rosemary essential oil or water may provide some scalp and hair advantages, but effectiveness depends on factors like:

  1. Quality of ingredients
  2. Proper use and dosage
  3. Existing hair and scalp health
  4. Possible sensitivities

To maximize potential gains while minimizing risks, consult a trichologist or dermatologist, especially if you have allergies, are pregnant, breastfeeding, or taking medications. With professional guidance, rosemary may complement your hair care regimen. But manage expectations, as results are highly individualized.

Focus on hair health fundamentals like a balanced diet, hydration, and reduced stress first.


As a dermatologist, I encourage you to keep realistic expectations if trying rosemary for hair. While some preliminary research shows potential, robust clinical data is lacking. The majority of evidence is anecdotal. Experiment carefully, as essential oils can irritate.

Monitor for redness or itching. And remember—there is no one quick fix that treats hair loss. Adopting healthy hair care habits, reducing stress, improving nutrition, and addressing underlying conditions holistically will support your hair’s health more than any singular product alone can.

However, incorporating rosemary as part of a natural hair care regimen likely cannot hurt.
