How to Dilute Rosemary Oil and Usage Tips for Hair Growth

Rosemary Oil is a plant-derived essential oil that has gained popularity as an all-natural treatment for hair growth. It is an essential oil with various beneficial effects, including anti-inflammatory and antioxidant properties.

Due to its concentrated nature, Rosemary Oil must be diluted with a gentle carrier oil or another base prior to applying it to the skin, scalp, or hair. Proper dilution ensures safe application, adequate absorption, and even distribution of the product. 

In this article, we will explain what Rosemary Oil is, its benefits, and the correct way to dilute the oil, and we will also answer some commonly asked questions about the oil for optimal results.

What Is Rosemary Oil?

Rosemary is a beautiful evergreen shrub originally grown in the Mediterranean region and cultivated worldwide. This perennial plant has unique aromatic characteristics, thanks to its citrus-like, herbaceous scent. Due to its fragrance, parts of the rosemary plant are used as a spice in many culinary dishes around the globe. 

In the past, Rosemary Oil has been used as a natural remedy to alleviate nervous system disorders and depression, and for its potential antinociceptive and analgesic properties. Research studies have revealed that inhaling Rosemary Oil may have an impact on central nervous system receptors, which can help to regulate and influence mood. These findings suggest that Rosemary Oil may serve as an effective and accessible natural treatment option for those seeking to improve their mental and emotional well-being.

The presence of phytochemical compounds, specifically in the leaves of the rosemary plant, can be utilized by extracting Rosemary Essential Oil from the leaves. The leaves can be dried or fresh prior to steam distillation, which is a type of extraction method. 

For steam distillation, the leaves can be freeze-dried or oven-dried, among other methods, and then subject to heat. Once the plant material is heated, the oil is collected during the condensation process. This method yields a highly concentrated oil that has beneficial properties, including antioxidant and anti-inflammatory effects, that may promote hair growth. 

Due to its potency, it is recommended to mix it with a carrier oil, such as grapeseed oil, to avoid skin irritation and adverse reactions. Diluting Rosemary Essential Oil before use also helps to enhance its therapeutic benefits. When mixed with a carrier oil, the blend can be applied topically to possibly promote hair growth and soothe skin irritation.

Benefits of Rosemary Oil

Rosemary Oil has been used for centuries for its possible medicinal properties; it contains bioactive compounds that contribute to its therapeutic effects. These compounds have been found to have anti-inflammatory, antimicrobial, and antioxidant properties, making it a powerful natural treatment for topical ailments.

One of the benefits of Rosemary Oil is its potential to promote hair growth. Androgenetic alopecia is a hair loss disease that affects men and women. This type of hair loss is caused by a hormone called dihydrotestosterone (DHT), which shrinks hair follicles and shortens the lifespan of hair. 

The major constituents of Rosemary Oil include 1,8-cineole, α- and β-pinene, rosmarinic acid, and camphor. These compounds contribute to the beneficial properties of Rosemary Oil. The compound 1,8-cineole has been found to have anti-inflammatory and analgesic effects, which could help decrease scalp inflammation and pain. α- and β-pinene are known for their antimicrobial properties, which may help to combat bacteria and fungi that can contribute to scalp infections. 

Rosmarinic acid is a potent anti-inflammatory that may relieve scalp irritation and redness. In addition, camphor may promote blood flow to the scalp, which could improve hair growth. Together, these compounds work to nourish the scalp, reduce inflammation, fight infections, protect against oxidative stress, and promote blood flow to the scalp, all of which may contribute to increased hair growth. One study showed that Rosemary Oil has spasmolytic activity, which may relax the scalp muscles to enhance blood flow and contribute to hair growth.

The antioxidant activity of Rosemary Oil may also help with hair loss, as oxidative stress is associated with alopecia. The scavenging of free radicals may reduce the severity of the oxidative stress, ultimately decreasing the amount of hair loss. Rosemary Oil also has nourishing properties that can lead to smooth hair.

How to Dilute Rosemary Oil

Essential oils are very concentrated natural oils that contain varying amounts of phytochemicals. While these compounds have beneficial properties, the potency of the oil could possibly irritate your skin if used directly. Some of the negative effects of using essential oils directly onto the skin include:

• Skin irritation: Essential oils, when undiluted, can cause irritation and redness on sensitive skin.
• Sensitivity to sunlight: Some essential oils, such as citrus oils, may increase sensitivity to sunlight, leading to sunburn or pigmentation issues.
• Allergic reactions: Individuals may experience allergies to specific essential oils, resulting in symptoms like itching or rash upon contact.
• Chemical burns: Direct application of undiluted essential oils can cause chemical burns, especially in areas with thin or sensitive skin.
• Skin dryness: Certain essential oils, if not properly diluted, may contribute to skin dryness and exacerbate existing dry skin conditions.

To dilute essential oils, you first have to choose a base to blend the oils with. This base can be a carrier oil or a gentle cosmetic formulation. Below is a list of bases to choose from.

Carrier Oils to Use With Rosemary Oil

• Jojoba Oil: This oil has a lightweight texture and is best for those with sensitive or oily skin.
• Sweet Almond Oil: Rich in antioxidants and fatty acids, this carrier oil will nourish and moisturize the skin and scalp.
• Grapeseed Oil: With a high concentration of linoleic acid, this oil is ideal for blemish-prone or oily skin. 
• Coconut Oil: This carrier oil makes a great pair with Rosemary Oil, as it has been shown to penetrate the hair shaft to nourish the hair strands.
• Argan Oil: This oil is highly nourishing and has anti-inflammatory compounds to soothe irritation and sensitive skin.
• Calendula Oil: The floral and earthy aroma of this oil can create a relaxing blend when paired with Rosemary Oil.
• Batana Oil: The oil may strengthen hair and improve scalp health. 

Shampoo

A simple way to incorporate Rosemary Oil into your hair care routine is to combine it with your shampoo. Add 2-3 drops of the Rosemary Oil to a teaspoon of your regular shampoo to enhance its hair growth properties and nourish your hair from the roots. Rosemary Oil may help to improve blood circulation to the scalp, which has the potential to stimulate hair growth. It also has antimicrobial properties that could possibly help prevent dandruff and other scalp concerns.

Other Cosmetic Bases

• Moisturizer: Mixing a few drops of Rosemary Oil with a soothing moisturizer is great for sensitive skin.
• Serum: Adding some Rosemary Oil to your favorite serum can enhance its anti-inflammatory and skin-moisturizing properties.

To properly dilute Rosemary Oil for safe use, a common recommendation is to add around 5-10 drops of Rosemary Oil per 30 mL of carrier oil or cosmetic base. To create the mixture, simply combine the specified amount of Rosemary Oil with the carrier oil or base in a clean, dry container. Stir the blend to ensure it is evenly distributed.

To store the diluted Rosemary Oil, use a dark glass bottle to protect the mixture from light exposure, as light can degrade the quality of essential oils. Ensure the bottle is sealed well to prevent air from entering and potentially oxidizing the oil. Store the blend in a dry, dark place, far away from any heat or sunlight. Always label the bottle with the date of preparation and the ingredients used.

Rosemary Oil Frequently Asked Questions 

If you are planning to use Rosemary Oil for hair growth, keep a few things in mind to get the best results. Whether you are using it to prevent hair loss, promote hair growth, or need application tips, the following answers to commonly asked questions about Rosemary Oil will help you use it effectively and safely.

How Often Should I Use Rosemary Oil for Hair Growth?

The frequency of use of Rosemary Oil on the scalp will vary depending on individual preferences. For example, this study instructed patients to apply diluted Rosemary Oil twice daily for 6 months; however, this method caused scalp itching and minor irritation in some participants, according to the results of the study. 

Therefore, it's important to start with a lower frequency and gradually increase it based on your individual needs and preferences. For some people, applying Rosemary Oil once a week may be sufficient to promote hair growth, while others may find that they benefit from using it more frequently. Continue to monitor your scalp and hair thickness and make adjustments accordingly. It's always a good idea to complete a patch test prior to applying any oils to your scalp to ensure that you don't experience any adverse reactions.

In terms of the length of use, it's generally recommended to use it consistently over a period of a few months to see noticeable results. While some people may experience immediate benefits after using the oil, it is important to remember that the effects of natural remedies can vary from person to person depending on their individual health and lifestyle factors. 

Can I Leave Rosemary Oil In My Hair Overnight?

If you want to use Rosemary Oil to improve your hair health, leaving it in your hair overnight can be a great option. However, it is important to use it carefully and safely.

Before leaving Rosemary Oil in your hair overnight, ensure that it is adequately diluted. This will help to prevent skin redness, irritation, or burning sensations. Once you have diluted the oil, apply it evenly to your hair and scalp, massaging it in thoroughly. You can dilute a fresh batch of the oil and add it to a comb bottle that squeezes out the mixture for easy application. Alternatively, you can use your fingertips to apply the mixture to the scalp. You can also cover your hair with a bonnet or shower cap to prevent staining your pillowcase while you sleep. 

In the morning, rinse your hair thoroughly with a mild shampoo and conditioner. You can repeat this process 1-2 times per week for best results. Always remember to complete a patch test before using Rosemary Oil to ensure that you are not allergic to it.

Can I Use Rosemary Oil Directly On My Hair?

As mentioned, Rosemary Oil is highly concentrated and contains potent chemical compounds that can harm the skin if used directly. This is also true when used directly on hair strands. The strands of hair are made primarily of fatty acids and protein, and contain a cuticle that provides a barrier to the external environment. 

When the hair comes into contact with undiluted essential oils, the oil may strip the cuticle and affect the protein content of the hair strands, damaging the physical and chemical structure of the hair. This damage can lead to breakage of the hair and split ends which can be difficult to treat. Therefore, it's always recommended to dilute Rosemary Oil before using it on hair or skin to avoid any potential damage.

How Do I Apply Rosemary Oil to the Scalp?

Applying Rosemary Oil to the scalp is a simple process that first requires you to dilute the Rosemary Oil. Once diluted, complete a patch test by adding a small amount of the mixture to the inside of your wrist, and monitoring the site for 24 hours to ensure no adverse reactions. 

When you're ready to apply the rosemary oil to your scalp, start by sectioning your hair into multiple pieces using a hair clip. This technique will enable even distribution of the blend across the scalp. You can use either a comb applicator or your fingertips to apply a small amount of oil to each section of the scalp. Massage the oil in circular motions using the pads of your fingers to promote hair growth.

After applying the Rosemary Oil to your scalp, leave it on for at least 30 minutes or even overnight. Then, rinse the oil off with shampoo and finish with conditioner to ensure that your hair is clean and moisturized.

Can Rosemary Oil Cause Hair Loss?

Rosemary Oil is a natural, plant-derived product free of synthetic chemicals, additives, and fragrances. It is safe to use on the skin, scalp, and hair and is generally well-tolerated by most people. However, it is important to note that individual sensitivity levels may vary, and patch testing is recommended before using this oil. 

With that said, there is currently no evidence suggesting that Rosemary Oil can cause hair loss. In fact, a study has shown that it yields comparable results to Minoxidil treatment, which is an FDA-approved hair loss treatment for androgenetic alopecia.
