In the quest for effective natural remedies, rosemary essential oil has gained significant attention for its potential to address hair loss. Rich in antioxidants and known for its stimulating properties, this aromatic oil has shown promise in promoting hair growth.

However, it’s important to be aware of the hazards associated with poor-quality rosemary oil, especially those high in ketones.

The Benefits of Rosemary Essential Oil for Hair Loss

Rosemary essential oil contains a range of substances, naturally found in the plant. These inherent chemicals have various actions and attributes that can help protect against hair loss:

  1. Stimulating Hair Follicles: Rosemary essential oil has a stimulating effect on the circulation, which results in increased blood supply to the scalp, thus promoting nutrient delivery to the hair follicles. This enhanced blood flow stimulates hair growth and can potentially reduce hair thinning.
  2. DHT Inhibition: Dihydrotestosterone (DHT) is a hormone linked to hair loss, particularly in cases of androgenic alopecia (baldness). Some studies suggest that rosemary essential oil may help inhibit the activity of DHT, preventing it binding to hormone receptors on the hair follicle. This slows down the progression of hair loss.
  3. Improved Scalp Health: The circulation stimulatory effects, in combination with antimicrobial and anti-inflammatory properties of rosemary oil can contribute to a healthier scalp. By maintaining a clean and balanced scalp environment, the conditions for hair growth are optimised.
  4. Increased Hair Thickness: Regular use of rosemary essential oil may lead to thicker and stronger hair strands. It is believed to strengthen the hair shaft, reducing breakage and enhancing overall hair health.


Cautions and Hazards of Poor-Quality Rosemary Oil

While rosemary essential oil is a useful adjunct for hair loss treatment, it is important to be aware that not all oils are created equal. Rosemary oil will vary according to the subspecies of the plant, the growing conditions, time of harvest and diligence of the oil producer.

There are potential hazards associated with using poor-quality oil, particularly those with high content of “unsafe” ketones:

  1. Skin Irritation: Low-quality rosemary oil might contain impurities or additives that can cause skin irritation or allergic reactions when applied to the scalp. Always opt for pure, high-quality rosemary essential oil from reputable sources.
  2. Toxicity: Some rosemary oils have high levels of ketones levels, particularly camphor. Ketones can be toxic if ingested or absorbed through the skin in excessive amounts. It’s crucial to dilute the essential oil properly before applying it to the scalp and perform a patch test to ensure you don’t experience adverse reactions.
  3. Neurological Effects: High levels of the ketone camphor, can have negative effects on the nervous system if used excessively. These effects range from headaches and dizziness to seizures.

How Do You Use Rosemary Oil for Hair Loss?

Using rosemary essential oil for treating hair loss requires proper application and dilution to ensure safety and effectiveness. Here’s a step-by-step guide on how to use rosemary essential oil for this purpose:

Conduct a Patch Test

Before using rosemary essential oil on your scalp for the first time perform a patch test on a small area of skin to check for any adverse reactions. Apply a diluted mixture of rosemary oil and carrier oil to your forearm or wrist, and wait 24 hours to ensure no irritation occurs. Read here for more information about essential oil safety, including patch testing.


1. Choose a Carrier Oil

Start by selecting a carrier oil to dilute the rosemary essential oil. Carrier oils are used to dilute the essential oil and prevent skin irritation. Popular choices include jojoba oil, coconut oil, and almond oil. Choose a carrier oil based on your preference and hair type. Jojoba has a long history of being used to support healthy hair.

2. Prepare the Mixture:
In a small glass bottle, mix the rosemary essential oil with your chosen carrier oil. A general guideline for dilution is to use about 3-5 drops of rosemary essential oil for every tablespoon (15ml) of carrier oil. Adjust the ratio based on your sensitivity and preferences.

3. Massage the Scalp:
Gently massage the diluted rosemary oil mixture onto your scalp using your fingertips. Focus on areas where hair loss is most noticeable or where you want to promote hair growth. The massaging action can help improve blood circulation to the hair follicles.

4. Wait. 
Leave the oil mixture on your scalp for at least 30 minutes to an hour. For better results, you can leave it on overnight, covering your hair with a shower cap or wrapping in a towel to prevent oil stains on your pillowcase.

5. Shampoo and Rinse:
After the desired time has passed, wash your hair using a mild, sulphate-free shampoo. Thoroughly rinse your hair to ensure all the oil is removed.

6. Frequency:
Initially, you can start by using this treatment 1-2 times a week. Depending on your hair’s response and your preferences, you can adjust the frequency. Consistency is key for seeing potential results.

7. Be Patient:
It’s important to note that natural remedies like rosemary oil may take time to show results. Hair growth and improvement in hair loss might not be immediately visible. Give it a few months of consistent use before expecting noticeable changes.

8. Give it a Boost:

Ginger essential oil also contains natural stimulants that help increase blood flow to the scalp. Add one or two drops of Rich Earth organic ginger essential oil to super-boost your hair protection regimen.

Always adhere to recommended dilution guidelines and use rosemary oil in moderation.


Rosemary essential oil has gained popularity as a natural remedy for hair loss due to its potential to stimulate hair follicles, inhibit DHT binding, and improve scalp health. However, it’s important to exercise caution and prioritise quality when selecting and using rosemary essential oil. Poor-quality oils and those high in ketones can pose hazards such as skin irritation, toxicity, and neurological effects.

Consulting with a healthcare professional or trained aromatherapist before incorporating rosemary essential oil into your hair care routine is advised, especially if you have sensitive skin, pre-existing health conditions, or concerns about potential interactions.
