Is rosemary oil good for your hair?
Rosemary oil is believed to stimulate hair growth, improve circulation to the scalp, and help with conditions like dandruff.
Dr. Aditi Shende, board-certified dermatologist says that although many people use rosemary oil as a natural remedy for hair care, there is a lack of scientific evidence supporting its effectiveness. Some small-scale studies suggest that rosemary oil may indeed have positive effects on hair growth, but more research is needed to confirm these findings conclusively.
Overall, Dr. Shende says that rosemary oil is considered safe for topical use on the hair and scalp, knowing that individual results may vary. She recommends doing a patch test before using any new essential oil or hair product to check for potential allergic reactions or sensitivities.
Additionally, if you are experiencing considerable hair loss, Dr. Shende says it is best to consult with a dermatologist who can provide you with a diagnosis and treatment plan. With male or female androgenetic alopecia and alopecia areata, the early intervention and treatment can make a big difference on your hair growth results.

However, there is a lack of scientific evidence to support its effectiveness in hair growth.
Why does rosemary oil make hair grow?
It is believed that rosemary can stimulate hair growth due to the carnosic acid, a compound abundant in sage and rosemary, both widely utilized in traditional medicine. Over the past decade, research indicates that carnosic acid exhibits some bioactive properties, including antioxidant, anti-inflammatory, and anticancer activities, among others.It also increases scalp microcirculation which facilitates hair growth.
Are there any rosemary oils for hair growth studies?
Yes, there are a few research studies on a small scale that seem to support the fact that rosemary oil stimulates hair growth.

These are safe for women and can be used long-term.
Should I use rosemary oil or a prescription medication for hair loss?
Dr. Shende says hair loss can have multiple causes. It is advisable to always consult a board-certified dermatologist for hair loss before starting any treatment. If you’re seeking faster and clinically proven results, prescription medication like minoxidil or finasteride might be more suitable. However, if you prefer a natural approach and are willing to wait for potential benefits, rosemary oil could be an option. Dr. Shende says that the decision between using rosemary oil or a prescription medication depends on the amount of hair loss you are experiencing and the way this hair loss is occurring.
If you are experiencing a few more hairs falling on the shower or hair brush, you may want to give rosemary oil a try, however, if your scalp has some bald patches or you have lost a considerable amount of hair is better to seek help from a dermatologist and get a professional diagnosis and treatment as the early intervention and treatment are always the best way to fight hair loss.
What is the best rosemary oil for hair growth?
Dr. Shende says that determining the “best” rosemary oil for hair growth can be subjective and depends on individual preferences, such as scent, purity, and personal experience.
However, when choosing rosemary oil for hair growth, consider the following factors:
- Purity: Look for 100% pure rosemary essential oil without any additives or dilution. High-quality, pure oils are more potent and effective.
- Organic Certification: Opt-in for organic rosemary oil to ensure it’s free from pesticides and harmful chemicals, which can potentially affect its efficacy.
- Extraction Method: Cold-pressed or steam-distilled extraction methods preserve the oil’s natural properties. Avoid oils extracted using harsh chemical solvents.
- Reputation and reviews: Research reputable brands with positive reviews from customers who have used the oil for hair growth purposes.
- Price: While price isn’t always an indicator of quality, extremely low-priced oils may be of lower quality or diluted with carrier oils.
Rosemary oil benefits for hair
Although there is a lack of scientific evidence that supports this, rosemary oil is believed to have the following benefits for the hair and scalp.
Reducing dandruff
Rosemary oil has antimicrobial properties that can help combat dandruff-causing fungi and bacteria when applied to the scalp.
Improving scalp health
Massaging rosemary oil into the scalp can improve circulation, help soothe irritation, reduce inflammation, and moisturize dry or itchy scalp conditions.
Strengthening hair
Rosemary oil contains antioxidants that may strengthen hair follicles, prevent damage from environmental stressors, and promote healthier, more resilient hair.
Enhancing shine
Regular use of rosemary oil can impart a natural shine to the hair, making it look healthier and more vibrant.
Masking odors
The pleasant aroma of rosemary oil can help mask unpleasant odors from the scalp and hair, leaving a refreshing scent.
How to use rosemary oil for hair growth?
Before using rosemary oil it is essential to know that it is a natural product. The FDA does not regulate it, hence, thorough research on the brand and quality is important before use. It may be unsafe for use by some. It is a highly concentrated oil, therefore, using excessive amounts may damage the hair follicles rather than causing hair growth.
People with allergic tendencies should use rosemary oil cautiously as it can cause allergic reactions or worsen existing skin conditions.
Dilute the rosemary oil
Do a patch test before using rosemary oil. Start by diluting rosemary oil with a carrier oil such as coconut, jojoba, or olive oil. Mix a few drops of rosemary oil with a tablespoon of carrier oil. This helps to prevent irritation and ensures even distribution. Avoid oils containing onion and garlic as they can lead to contact dermatitis.
Massage into the scalp
Once diluted, gently massage the oil mixture into your scalp using your fingertips. Focus on areas where you want to stimulate hair growth or where you experience thinning or hair loss.
Leave it on for 30 minutes
Leave the oil on your scalp for at least 30 minutes to allow the nutrients to penetrate the hair follicles.
Wash your hair
After the desired time, wash your hair as usual with a mild shampoo to remove the oil. You may need to shampoo twice to ensure all the oil is rinsed out.
How often should I put rosemary oil in my hair?
For best results, use rosemary oil 2-3 times a week.
Is it safe to leave rosemary in my hair overnight?
While rosemary oil itself is safe, Dr. Shende advises against leaving it in your hair overnight because it can disrupt the scalp’s microflora which may lead to itchiness and redness, and the same applies to all oils, not just rosemary oil.
How much rosemary oil should I use for hair growth?
There is a lack of standardized dosing and percentage of rosemary oil. However, the amount of rosemary oil you should use for hair growth depends on several factors, including your hair length, scalp sensitivity, and personal preference.
As a general guideline, Dr. Shende says you can start with a small amount and adjust as needed.
- It is essential to dilute rosemary oil with a carrier oil to prevent irritation and ensure even distribution. A common dilution ratio is around 2-3% rosemary oil to carrier oil. For example, if you’re using 1 tablespoon (15 mL) of carrier oil, you can add 4-6 drops of rosemary oil.
- Focus on applying the oil mixture to your scalp rather than saturating your hair strands. The goal is to massage the oil into your scalp to stimulate hair follicles.
- Start with a conservative amount of rosemary oil and observe how your scalp reacts. If you do not experience any adverse effects, you can gradually increase the amount if desired.
- Consider how often you plan to use rosemary oil for hair growth. If you’re using it multiple times a week, you may use a smaller amount each time compared to using it less frequently.
When will I start seeing any results from using rosemary oil for hair growth?
Since there is a lack of evidence whether rosemary oil consistently works for hair growth it is hard to tell. However, if you do not notice any new hairs in three months time, you can discontinue using the oil and consult an online dermatologist to get adequate treatment.
What else can you do?
A few studies show that using a derma roller and topical minoxidil can also stimulate hair growth, so you can try that to see if it works.
Conclusion
There is a growing popularity of rosemary oil in social media. While there is no harm in using rosemary oil, it should only be used as an adjuvant treatment.
If you are experiencing serious hair loss it is important not to delay seeing a dermatologist. In many cases, the use of these products tends to lead to a delayed consultation with a certified dermatologist who can provide you with adequate treatment which means time and money is wasted on the use of these products.
