Rosemary Oil: The Many Faces Of Rosemary
Rosemary (Salvia rosmarinus, formerly Rosmarinus officinalis) is much more than a familiar culinary herb. Its strongly aromatic leaves have also been incorporated into traditional herbal preparations, hair and scalp routines, skincare products, and aromatic blends.
But when someone mentions rosemary oil, they may be talking about two very different preparations: concentrated rosemary essential oil or rosemary-infused carrier oil.
Understanding the difference matters because these products are made differently, used differently, and require different safety considerations.
In this beginner-friendly guide, you’ll learn about the different types of rosemary oil, their traditional and everyday uses, what research says about rosemary and hair care, and how to make a simple rosemary-infused oil at home.
What Is Rosemary Oil?
Rosemary oil can refer to more than one herbal preparation. Two of the most common are rosemary essential oil and rosemary-infused oil.
Rosemary Essential Oil
Rosemary essential oil is a highly concentrated aromatic oil, typically obtained through steam distillation of rosemary plant material.
Because essential oil is concentrated, it generally shouldn’t be applied directly to the skin without appropriate dilution.
Rosemary-Infused Oil
Rosemary-infused oil is made by allowing rosemary to infuse into a carrier oil such as olive, jojoba, sunflower, or another suitable oil.
The carrier oil extracts some of the oil-soluble constituents and aroma of the herb.
This preparation is considerably different from distilled rosemary essential oil.
Rosemary Oil Benefits & Traditional Uses
Rosemary has a long history of culinary, aromatic, and traditional herbal use. Today, rosemary essential oil and rosemary-infused preparations are commonly incorporated into personal-care routines, particularly products intended for the hair, scalp, skin, massage, and aromatherapy.
Some uses have received scientific study, while others are based primarily on traditional practice or cosmetic use. These shouldn’t be treated as equivalent evidence.
Hair & Scalp Care
Rosemary preparations are frequently incorporated into scalp oils, shampoos, conditioners, and other hair-care products.
Massage & Body Oils
Properly diluted rosemary essential oil can add its characteristic herbaceous aroma to massage oils, while rosemary-infused oil can serve as a botanical body oil.
Skin & Body Care
Rosemary-infused oils can be incorporated into homemade salves and other topical preparations when appropriate for the individual.
Aromatic Use
Rosemary essential oil’s strong herbaceous aroma makes it popular in diffusers and aromatic blends.
What Does Research Say About Rosemary Oil for Hair?
Rosemary oil has attracted considerable attention as an ingredient in scalp and hair-care routines.
One randomized comparative study followed people with androgenetic alopecia for six months and compared rosemary oil with 2% minoxidil. Hair counts didn’t significantly increase in either group after three months, but increases were observed in both groups after six months. The study did not find a significant difference in hair count between the two groups.
That’s interesting preliminary evidence, but it doesn’t mean rosemary oil has been proven to work for every type or cause of hair loss, nor should rosemary oil automatically be considered a replacement for medical treatment.
Hair loss has many possible causes. Sudden, unexplained, patchy, or persistent hair loss deserves evaluation by an appropriate healthcare professional.
How to Use Rosemary Essential Oil for Hair
Add It to a Carrier Oil
Rosemary essential oil can be appropriately diluted in a skin-compatible carrier oil and used as part of a scalp-care routine.
Possible carrier oils include:
Jojoba oil • Argan oil • Grapeseed oil • Fractionated coconut oil
Rather than giving readers a universal number of drops, tell them to follow the dermal-use guidance for the specific rosemary essential oil product they’re using.
Add It to Hair Products
An appropriately formulated rosemary product can also be incorporated into a hair-care routine through shampoos, conditioners, scalp oils, or commercially prepared products.
Rosemary-Infused Hair Oil
For readers who prefer a less concentrated herbal preparation, homemade rosemary-infused oil is another option.
How to Make Rosemary-Infused Oil at Home
This should become one of the centerpiece sections of the article.
You’ll Need
- Dried rosemary
- Clean, completely dry glass jar
- Carrier oil of your choice
- Fine-mesh strainer or cheesecloth
- Clean storage bottle
- Label
Beginner Tip: I recommend dried rosemary rather than fresh rosemary for a beginner oil infusion because introducing water from fresh plant material can increase spoilage concerns.
Ways to Use Rosemary-Infused Oil
Hair & Scalp Oil
🌿
Use your rosemary-infused oil as part of a hair and scalp-care routine if its ingredients are appropriate for your skin.
Massage Oil
🌿
The finished infusion can serve as a botanical massage or body oil, depending on the carrier oil selected.
Herbal Salves
🌿
Use rosemary-infused oil as the oil portion of a homemade herbal salve.
DIY Body-Care Recipes
🌿
Experiment with the infused oil in simple topical preparations where an oil-based ingredient is appropriate.
What About Rosemary Hydrosol?
Rosemary hydrosol is the aromatic water produced during the steam-distillation process used to make rosemary essential oil.
Hydrosols contain water-soluble aromatic compounds and very small amounts of volatile components, making them distinctly different from concentrated essential oils.
Rosemary hydrosol is commonly incorporated into cosmetic formulations, facial or body mists, and hair-care preparations.
Because hydrosols are water-based products, their storage and microbial-safety considerations are also different from those of essential oils or properly prepared oil infusions.
Rosemary Oil Safety
Rosemary essential oil is highly concentrated and should be used thoughtfully.
For topical use: Dilute essential oils appropriately and follow product-specific dermal safety guidance. Stop using a preparation if irritation or another reaction develops.
Don’t ingest rosemary essential oil simply because rosemary itself is a culinary herb. The essential oil is a much more concentrated preparation.
Keep essential oils away from the eyes and mucous membranes and store them securely away from children and pets.
People who are pregnant or breastfeeding, have medical conditions, take medications, have a history of seizures, or are considering essential-oil use for a child should seek individualized professional guidance when appropriate.
