Rosemary: The Ultimate Herb for Hair and Skin Health


Rosemary, or Rosmarinus officinalis, is a woody perennial herb native to the Mediterranean region. With its fragrant, needle-like leaves and blue flowers, rosemary has been cherished for centuries for its culinary and medicinal properties. Traditionally, it has been used to enhance memory, improve digestion, and relieve muscle pain. But rosemary also has impressive benefits for skin care, making it a versatile ingredient in the beauty industry.

The History of Rosemary Use in Skin Care and Hair Care

Ancient Civilizations

The ancient Egyptians were among the first to use rosemary in cosmetics and beauty treatments. They included rosemary oil in their skincare regimens and used it for its aromatic and preservative properties. Rosemary was often combined with other herbs and oils to create embalming mixtures and skin salves, too.

Greeks and Romans

Both Greeks and Romans utilized rosemary in their bathing and beauty routines. They infused bathwater with rosemary to rejuvenate the skin and used rosemary oils to condition their hair and scalp. Rosemary was believed to promote hair growth and add shine.

Medieval Europe

During the Middle Ages, rosemary was used in various beauty concoctions. Women used rosemary-infused water as a facial toner to refresh and cleanse their skin. It was also common to create hair rinses with rosemary to improve scalp health and hair quality.

Early Modern Periods

The Renaissance saw a revival of herbal medicine and cosmetics, and rosemary became a popular ingredient in beauty products. It was incorporated into creams, lotions, and perfumes. The herb’s natural antiseptic and anti-inflammatory properties made it suitable for skincare formulations aimed at treating acne and other skin conditions.

16th and 17th Centuries

During these centuries, herbalists like Nicholas Culpeper documented the use of rosemary in beauty treatments. Rosemary water was distilled and used as a facial cleanser and toner. It was also added to pomades and hair oils to enhance hair health and appearance.

18th and 19th Century

In the 18th century, the production of beauty products became more refined, and rosemary continued to be a popular ingredient. Rosemary-infused oils and waters were marketed for their purported benefits in improving skin texture and complexion. Victorian women used rosemary hair rinses to achieve glossy, healthy hair, and rosemary perfumes were valued for their fresh, invigorating scent.

20th and 21st Century

The early 20th century saw the industrialization of cosmetic production. Rosemary became a staple ingredient in shampoos, conditioners, facial creams, and toners due to its antiseptic, anti-inflammatory, and aromatic properties. Today, rosemary is widely used in the beauty and personal care industry. It is found in a variety of products, including skin care, hair care, and spa treatments.

What are the Active Compounds in Rosemary?

Rosemary is rich in notable skin benefitting compounds. Here are some of the most significant compounds found in rosemary:

Carnosic Acid

Carnosic acid is a powerful antioxidant that protects the skin from free radical damage. It helps reduce inflammation and prevents oxidative stress, which can lead to premature aging.

Rosmarinic Acid

Rosmarinic acid is another strong antioxidant and anti-inflammatory agent. It helps soothe irritated skin, reduce redness, and combat the effects of UV exposure.


Carnosol has anti-inflammatory and anti-tumor properties. It works by interfering with inflammation signals in the skin, reducing skin inflammation and promoting healing.

Ursolic Acid

Ursolic acid is known for its anti-inflammatory and antimicrobial properties. It helps protect the skin from infections and can reduce the appearance of acne and blemishes.

1,8-Cineole (Eucalyptol)

1,8-Cineole is an essential oil component with antimicrobial and anti-inflammatory properties. It aids in clearing pores and reducing acne, making it an excellent addition to skin care products.

Fatty acids 

Rosemary is rich in various hydrating and anti-inflammatory fatty acids such as linoleic acid, palmitic acid, oleic acid, and stearic acid. Each of these fatty acids plays a role in skin moisturizing and preventing transdermal water loss.

How Does Rosemary Benefit Skin Health and Appearance?

1. Antioxidant Properties

Free Radical Protection: Rosemary is rich in antioxidants like rosmarinic acid and carnosic acid, which help protect the skin from damage caused by free radicals. Free radicals can accelerate the aging process and lead to the formation of fine lines, wrinkles, and age spots.

Anti-Aging Effects: By neutralizing free radicals, rosemary can help slow down the signs of aging, making the skin look younger and more vibrant.

2. Anti-Inflammatory Effects

Reduces Inflammation: The anti-inflammatory properties of rosemary can help reduce skin inflammation, making it beneficial for conditions like acne, eczema, and rosacea.

Soothes Irritated Skin: It can soothe irritated and sensitive skin, providing relief from redness and swelling.

3. Antimicrobial and Antibacterial Properties

Fights Bacteria: Rosemary has natural antibacterial properties that help fight acne-causing bacteria, reducing the occurrence of pimples and breakouts.

Prevents Infections: It can help prevent minor skin infections and promote faster healing of cuts and wounds.

4. Improves Circulation

Enhances Blood Flow: Rosemary can stimulate blood circulation when applied topically, which helps deliver more oxygen and nutrients to the skin. This can improve overall skin tone and health.

Revitalizes Dull Skin: Improved circulation can revitalize dull and tired-looking skin, giving it a more radiant appearance.

5. Astringent Properties

Tightens Pores: Rosemary acts as a natural astringent, helping to tighten and tone the skin. This can reduce the appearance of large pores and make the skin look smoother.

Controls Oil Production: Its astringent effects also help control excess oil production, making it suitable for oily and acne-prone skin types.

6. Hydration and Moisturization

Retains Moisture: Rosemary helps the skin retain moisture, preventing dryness and flakiness. This makes it beneficial for maintaining healthy and hydrated skin.

Balances Skin: It helps balance the skin's natural oils, ensuring that the skin is neither too oily nor too dry.

7. Improves Skin Texture

Exfoliation: Rosemary can help gently exfoliate the skin, removing dead skin cells and promoting cell turnover. This leads to a smoother and more even skin texture.

Promotes Healing: Its healing properties can aid in the repair of damaged skin, reducing the appearance of scars and blemishes.

How Does Rosemary Benefit Hair Health and Appearance?

1. Stimulates Hair Growth

Improves Circulation: Rosemary oil can improve blood circulation to the scalp, ensuring hair follicles receive more nutrients and oxygen. This can stimulate hair growth and help prevent hair loss.

Reduces Hair Loss: Studies have shown that rosemary oil can be as effective as minoxidil, a common hair growth treatment, in reducing hair loss, particularly in cases of androgenetic alopecia.

2. Strengthens Hair

Prevents Hair Breakage: The nutrients in rosemary, including iron, calcium, and vitamins, help strengthen hair strands and prevent breakage and split ends.

Enhances Hair Thickness: Regular use of rosemary oil can improve hair thickness and density, making hair look fuller and healthier.

3. Improves Scalp Health

Antimicrobial Properties: Rosemary has natural antimicrobial properties that help keep the scalp clean and free from infections. This can help prevent conditions such as dandruff and scalp acne.

Reduces Dandruff: Its anti-inflammatory and antifungal properties can help reduce dandruff and flaky scalp conditions. Rosemary can help soothe the scalp and reduce itchiness associated with dandruff.

4. Conditions and Adds Shine

Natural Conditioner: Rosemary can be used as a natural conditioner to make hair softer and shinier. It helps in locking moisture into the hair, preventing dryness and frizz.

Adds Shine: By smoothing the cuticles of the hair, rosemary helps to enhance the natural shine of the hair, making it look healthier and more vibrant.

5. Prevents Premature Graying

Antioxidant Protection: The antioxidants in rosemary can help protect hair from damage caused by free radicals, which can contribute to premature graying. While it won’t reverse gray hair, it can help slow down the process.

6. Balances Oil Production

Regulates Sebum Production: Rosemary helps balance the scalp's oil production, which is beneficial for both oily and dry scalps. For oily scalps, it reduces excess oil, and for dry scalps, it helps maintain adequate moisture levels.

What Skin Concerns Does Rosemary Target?

1. Acne and clogged pores

Rosemary’s antimicrobial properties make it effective in treating acne and preventing future breakouts. It helps reduce the bacteria that cause acne and soothes inflamed skin.

2. Eczema and Dermatitis

The anti-inflammatory compounds in rosemary can help manage symptoms of eczema and dermatitis by reducing redness and irritation through its beneficial, soothing fatty acids.

3. Oily Skin

Rosemary helps balance sebum production, making it beneficial for those with oily skin. It helps reduce excess oil without stripping the skin of its natural moisture. That said, if you have extremely oily skin, it is usually a good idea to add even more oils. Instead of a creamy cleanser (where you might find rosemary), a foaming cleanser is typically better for oily skin.

What Hair Concerns Does Rosemary Target?

1. Thinning Hair

By repairing the skin barrier on the scalp and penetrating into the individual hair strands, rosemary can facilitate healthier hair growth. Hairs can be damaged from dryness or excess oils just like your face can be.

2. Dandruff

Its antimicrobial properties help combat dandruff by keeping the scalp clean and free from fungal infections. If your dandruff is from dryness instead of a fungus, rosemary can also help; hydrating the scalp and repairing it’s barrier can also keep dandruff at bay.

3. Damaged and Brittle Hair

Regular use of rosemary oil can strengthen hair, reduce breakage, and prevent split ends. This is because rosemary is able to absorb into individual hair strands and strengthen them with its various beneficial compounds.

4. Dull and Lackluster Hair

Rosemary is an emollient, meaning it reflects light off the face (not UV rays, but visible light), creating a shine on the skin.


Rosemary is a versatile and powerful ingredient in both skin and hair care. Its rich array of bioactive compounds offers numerous benefits, from anti-aging and anti-inflammatory effects to acne treatment and hair growth stimulation. While it’s generally safe for most skin types, always perform an allergy test or consult with a dermatologist if you have specific skin concerns or conditions. Embrace the natural goodness of rosemary! Seasoning for the skin.
