There are so many benefits of rosemary oil for hair growth! learn step-by-step how to prevent hair loss with the best rosemary oil tips!


Factors for Hair Loss / Hair Thinning

Hair loss and hair thinning can be distressing, but understanding the root causes can help you address the problem effectively. Here are some key factors that can lead to hair loss or thinning:


One of the primary factors behind hair loss is genetics. If your family has a history of hair loss, you might be more prone to experiencing it as well. This type of hair loss is often referred to as androgenetic alopecia.


As you age, your hair naturally becomes thinner and more prone to falling out. The hair growth cycle slows down, and the hair follicles shrink, leading to finer hair and more scalp visibility.


High levels of stress can significantly impact your hair health. Stress can trigger conditions like telogen effluvium, where hair follicles enter a resting phase, causing hair to fall out more easily.


Certain hairstyles that pull tightly on your hair, like ponytails, braids, and buns, can cause traction alopecia. This condition occurs when the hair is constantly under tension, leading to hair loss.

Oily Scalp

An overly oily scalp can clog hair follicles, preventing new hair from growing. It can also lead to dandruff and scalp infections, which further contribute to hair loss.

Scalp Conditions

Scalp conditions such as psoriasis, eczema, and fungal infections can cause itching, inflammation, and damage to hair follicles. These conditions often lead to hair thinning and loss.

Rapid Weight Loss

Losing weight too quickly can result in nutritional deficiencies, which impact hair health. Your body might not get enough essential nutrients needed for hair growth, causing your hair to become weak and fall out.

Nutritional Deficiencies

A diet lacking in essential vitamins and minerals, such as iron, zinc, and vitamin D, can lead to hair thinning. Your hair needs these nutrients to grow strong and healthy.

Illness: Thyroid Disease, Autoimmune Disease

Certain illnesses like thyroid disease and autoimmune diseases can disrupt the normal hair growth cycle, leading to hair loss. These conditions often require medical treatment to manage hair loss effectively.


Some medications, including those for cancer, arthritis, depression, heart problems, and high blood pressure, can have side effects that include hair loss.


Postpartum hair loss is common among new mothers. Hormonal changes after childbirth can cause significant hair shedding, but this is usually temporary, and hair growth typically resumes within a few months.


Benefits of Rosemary Oil for Hair?

Rosemary oil is gaining popularity as a natural remedy for various hair problems. Its numerous benefits are supported by both traditional uses and modern research. Let's explore how rosemary oil can help with your hair:

Promote Hair Growth

Rosemary oil for hair growth is one of the most talked-about benefits. Studies have shown that rosemary oil may help stimulate hair follicles, encouraging new hair growth. Applying rosemary essential oil to your scalp can increase blood circulation, bringing more nutrients to your hair follicles. This can lead to thicker, longer hair over time.

Reduce Hair Loss

Using rosemary oil can also help to prevent hair loss. Research has indicated that rosemary oil was as effective as certain medical treatments for reducing hair loss. It works by inhibiting the hormone dihydrotestosterone (DHT), which is responsible for shrinking hair follicles. Regular use of rosemary oil can help maintain the strength and health of your hair, thereby reducing hair fall.

Improve Scalp Health

A healthy scalp is crucial for healthy hair, and rosemary oil excels in improving scalp conditions. It has anti-inflammatory and antimicrobial properties that can alleviate scalp issues such as dandruff, psoriasis, and eczema. By applying rosemary oil to your scalp, you can reduce irritation and create an environment conducive to hair growth. Additionally, the oil helps in balancing the natural oils on your scalp, preventing excess oiliness or dryness.

Thicken Hair Strands

If you are looking to add volume to your hair, rosemary oil can be beneficial. It helps in thickening hair strands by strengthening the hair shaft. The nutrients in rosemary oil penetrate deep into the hair, fortifying it from the inside out. This not only makes your hair look fuller but also makes it less prone to breakage.


How to Use Rosemary Oil for Hair Growth? Your Hair Care Guide

Now that you know the benefits of rosemary oil for hair growth, here’s a detailed step-by-step guide on how to use it effectively.

Wash Hair and Exfoliate Scalp

Start by double shampooing to thoroughly clean your hair and scalp. This process ensures that any product buildup, oil, and dirt are completely removed. Using an exfoliating shampoo can further help to slough off dead skin cells and unclog pores. This creates a healthy environment for hair growth. For an extra boost, use a manual scalp massager. Simply squeeze some shampoo onto your wet hair and scrub your head with the massager in small circular motions. The stimulation from the massager not only enhances blood circulation, which can activate hair growth, but also provides a relaxing experience. Depending on how oily your scalp is, you should wash your hair like this every 1 to 3 days. Over-washing can strip your hair of natural oils, so it's essential to find the right balance.

Use Conditioner, Hair Mask or Similar Hair Products

Using a hair conditioner is essential for maintaining hair health. Select a conditioner that suits your specific hair needs. For instance, if hair loss is a concern, choose a hair growth conditioner enriched with ingredients like biotin and keratin to strengthen hair strands. For other needs, opt for a moisturizing conditioner if you have dry hair or a color-keeping conditioner to preserve dyed hair. For bleached or damaged hair, a hair mask can be a lifesaver. Some masks can be used in the shower and washed off after 5 to 15 minutes, while others should be left in overnight for deeper nourishment. When applying thick or creamy products, focus on the mid to end sections of your hair to avoid making your scalp oily and clogging hair follicles, which can hinder hair growth.

Dry Your Hair Properly

Proper drying techniques are crucial to prevent hair damage. After washing, gently squeeze out excess water from your hair using your hands. Towel-dry your hair until it's about 70% dry, but avoid rubbing your hair with the towel as this can cause frizz and breakage. Instead, use a microfiber, satin, or soft cotton towel to gently pat your hair dry. These materials are softer on your hair and help to minimize damage and frizz.

Dilute Rosemary Oil for Hair and Scalp Massage

Rosemary oil is highly concentrated and should not be applied directly to your scalp and hair. It can cause irritation or even damage hair follicles if used undiluted. Dilute rosemary oil with a carrier oil like jojoba oil or coconut oil. For those with oily scalps, lighter carrier oils like grapeseed oil or almond oil are preferable as they are less likely to clog pores. Mix 15 drops of rosemary oil with 1.5 tablespoons of carrier oil and massage the mixture into your scalp and hair from roots to ends for about 15 minutes. This massage not only helps the oil penetrate deeply but also stimulates blood flow to the scalp, which can encourage hair growth.

Gently Pat Away Excess Rosemary Oil In Your Hair

After the massage, excess oil can make your hair greasy and limp, and clogging your hair follicles can affect hair growth. Use the same gentle drying technique to remove any excess rosemary oil from your hair and scalp. Pat your hair gently with a soft towel to soak up the excess oil without disturbing the scalp.

Rinse / Leave Rosemary Essential Oil On

Depending on your hair type, you can decide whether to leave the rosemary oil on overnight or rinse it out. For dry or damaged hair, leaving the oil on overnight can provide deep conditioning and repair. For normal or oily hair, it’s better to rinse it out with lukewarm to cool water after 30 minutes to an hour. Avoid leaving the oil in if you’ve used too much, as indicated by greasy hair, as it can weigh down your hair and make it look flat.

Blow-Dry Your Scalp and Hair

Blow-drying your hair correctly can prevent heat damage. Use the cool setting on your hair dryer to avoid high temperatures that can damage hair strands. Before blow-drying, apply a heat protectant spray, lotion, or gel from roots to ends. Choose products without silicon to prevent clogging hair follicles. Hold the dryer at a forearm-length distance from your hair while drying to distribute the heat evenly and avoid focusing too much on one spot, which can cause heat damage.


Potential Side Effects of Using Rosemary Oil for Hair Loss

While rosemary oil offers numerous benefits for hair, it's important to be aware of potential side effects. Here are some of the issues you might encounter:


Rosemary oil is potent and can cause irritation if applied directly to your scalp. This is particularly true for individuals with sensitive skin. Symptoms of irritation include redness, itchiness, and a burning sensation. To avoid these issues, always dilute rosemary oil with a carrier oil such as jojoba oil or coconut oil before application.

Allergic Reaction

Although rare, some people may experience allergic reactions to rosemary oil. Symptoms of an allergic reaction can include rashes, hives, and difficulty breathing. It’s crucial to do a patch test before using rosemary oil extensively. Apply a small amount of the diluted oil to a patch of skin on your arm and wait 24 hours to see if any reaction occurs. If you notice any signs of an allergic reaction, avoid using rosemary oil on your scalp.


Rosemary oil may increase your scalp’s sensitivity to the sun. This condition, known as photosensitivity, can lead to sunburns or other skin damage when your scalp is exposed to sunlight. To protect your scalp, make sure to wear sunscreen or a hat when spending time outdoors after applying rosemary oil. This precaution helps prevent potential sun damage and maintains the health of your scalp.

Interaction with Medications

Rosemary oil may interact with certain medications, particularly those affecting blood pressure or blood thinning. If you are taking medications such as anticoagulants or antihypertensives, consult your doctor before using rosemary oil. This is to ensure that the oil does not interfere with your medication regimen and cause adverse effects.

What Else to Know Before Using Rosemary Oil: Who Should Not Do So?

While rosemary oil can be highly beneficial for many, there are certain groups of people who should avoid using it on their hair and scalp. Here's who should be cautious:

People with Allergies to Rosemary or Essential Oils

If you have a known allergy to rosemary or other essential oils, it's best to avoid using rosemary oil on your hair and scalp. Allergic reactions can range from mild irritation to severe symptoms like difficulty breathing.

Individuals with Sensitive Skin

Those with particularly sensitive skin might find rosemary oil too harsh, even when diluted. Symptoms like redness, itchiness, and irritation may occur. If you have sensitive skin, it's wise to perform a patch test or consult a dermatologist before incorporating rosemary oil into your hair care routine.

Pregnant or Breastfeeding Women

Although rosemary oil is generally considered safe, its potent nature means it should be used with caution during pregnancy and breastfeeding. Essential oils can have powerful effects, and it's best to consult with a healthcare provider to ensure that rosemary oil won't pose any risks to you or your baby.

Individuals with Epilepsy or Seizure Disorders

Rosemary oil contains compounds that might trigger seizures in individuals with epilepsy or other seizure disorders. If you have a history of such conditions, it's crucial to consult your doctor before using rosemary oil.

People on Certain Medications

As mentioned earlier, rosemary oil can interact with medications, especially blood thinners and those affecting blood pressure. If you're taking such medications, seek medical advice before adding rosemary oil to your hair care regimen.


Children have more sensitive skin compared to adults, and the concentrated nature of rosemary oil can be too harsh for their scalps. It's generally recommended to avoid using essential oils on children unless advised by a healthcare professional.
