How To Use Rosemary Oil For Hair Growth

In the quest for luscious locks, people often seek out various remedies. One natural solution that has been gaining popularity is Rosemary oil. This aromatic herb, frequently used for culinary purposes, also carries a multitude of benefits for hair health. From battling hair loss to boosting shine, rosemary oil for hair growth has become a popular choice for those seeking a more natural approach to hair care.


This guide aims to delve into the science behind rosemary oil and its potential impact on hair growth. It will provide insights on how to use rosemary oil for hair growth, the benefits, the scientific evidence supporting its use, the results you can expect, and any potential side effects.

1. Introduction to Rosemary Oil

Rosemary oil is derived from the aromatic rosemary plant, native to the Mediterranean region. The extraction process yields a pale oil with a distinctly herbaceous aroma. Its popularity in perfumes, skincare, and hair care products can be attributed to its antioxidant, anti-inflammatory, and antimicrobial properties.

The oil has also found its place in the world of hair care, primarily due to its potential benefits in promoting hair growth. However, the application of rosemary oil extends beyond just hair growth. It's also touted for its potential to combat dandruff, alleviate dry scalp, and enhance hair shine.

2. The Science Behind Rosemary Oil for Hair Growth

The primary reason behind rosemary oil's rising popularity in hair care is its potential to stimulate hair growth. This benefit is primarily attributed to a compound found in the rosemary plant known as carnosic acid. Studies suggest that carnosic acid can heal nerve and tissue damage and improve cellular turnover.

In terms of hair growth, this implies that carnosic acid can stimulate nerve growth, improve blood circulation, and ensure that the hair follicles receive essential nutrients for growth. This is crucial since without a proper blood supply, the follicles may not obtain the nourishment they need, leading to hair thinning or loss.

Rosemary oil's potential to stimulate hair growth extends beyond just improving blood circulation. Research suggests that it may also block the effects of Dihydrotestosterone (DHT). DHT is a derivative of testosterone, often responsible for shrinking hair follicles, leading to hair loss.

Moreover, the anti-inflammatory and antimicrobial properties of rosemary oil make it an excellent solution for scalp health. It can help soothe an irritated scalp and control yeast and bacteria levels, further promoting a healthy environment for hair growth.

3. Rosemary Oil for Hair: The Benefits

The use of rosemary oil in hair care is not limited to promoting hair growth. There are several other benefits that this aromatic oil brings to the table.

3.1. Enhancing Hair Thickness

One of the lesser-known benefits of rosemary oil is its potential to enhance hair thickness. Research suggests that effective blood circulation can encourage the growth of new hair follicles and increase their size. This implies that regular use of rosemary oil could potentially contribute to increased hair thickness.

3.2. Scalp Health

Rosemary oil's anti-inflammatory properties can significantly benefit scalp health. An irritated or inflamed scalp can often hinder hair growth. By soothing the scalp and reducing inflammation, rosemary oil can help create the right environment for hair growth.

3.3. Combating Hair Loss

Rosemary oil's ability to fight against free radicals can also play a role in preventing hair loss. Free radicals are molecules that can cause cell damage over time. When it comes to hair, this could mean damage to the hair follicle, which could eventually lead to hair loss.

3.4. Dandruff Control

Besides promoting hair growth, rosemary oil can also aid in controlling dandruff. Its antimicrobial properties can help eliminate bacteria that clog the hair follicles. Furthermore, by improving blood circulation to the scalp, rosemary oil can potentially reduce the occurrence of dandruff flakes.

3.5. Delaying Grey Hair

Preliminary research suggests that rosemary oil might play a role in slowing down the hair greying process. The oil's free radical-fighting properties could potentially delay the ageing processes, including hair greying. However, more research is needed to fully understand this potential benefit. Rice hair oil is widely known for delaying grey hair.

4. Expectations: How Long for Results?

The effectiveness of rosemary oil for hair growth can vary from person to person. Moreover, hair growth is a slow process, and it may take several months before visible results are noticeable. In a study comparing rosemary oil to minoxidil, a popular hair growth treatment, significant increases in hair growth were only observed after six months of consistent use.

5. Who Can Use Rosemary Oil?

Rosemary oil is generally considered safe for all hair types, including colour-treated hair. This is because the benefits of the oil target the hair follicle, not the hair strand. However, individuals with sensitive skin or a history of allergies should consult a dermatologist before incorporating rosemary oil into their hair care routine. Conducting a small patch test before full application can also help identify any potential irritation or allergic reactions.

Pregnant or breastfeeding women should avoid using rosemary oil unless advised by a healthcare professional.

6. Comparing Rosemary Oil to Other Oils

When compared to other oils used in hair care, like tea tree and peppermint, rosemary oil holds its own due to its hair follicle health benefits. However, it should be used more sparingly than carrier oils as overexposure could potentially irritate the skin.

7. Possible Side Effects of Rosemary Oil

While rosemary oil is generally safe to use, it's important to be aware of potential side effects. For individuals with thin or fine hair, or a sparse density of hair, the oils can make the hair look greasy and weighed down. In such cases, using the product as a pre-shampoo treatment can be beneficial.

8. Frequency of Rosemary Oil Application

The frequency of rosemary oil application can depend on the individual's hair type and the specific issues they are addressing. For instance, if you're trying to control itching due to dandruff, using the oil mixed with compounds three to four times a week could be beneficial. However, for individuals with very fine hair and/or an oily scalp, using rosemary oil once a week as a scalp treatment could be more appropriate.

9. Leaving Rosemary Oil in Hair Overnight

While rosemary oil is not harmful, leaving it in the hair overnight is not recommended. Leaving any type of oil on the scalp for an extended period can upset the balance of the scalp's microflora, potentially leading to itchiness and redness.

10. How to Use Rosemary Oil for Hair Growth

The use of rosemary oil for hair growth can take various forms. Some of the common methods include:

10.1. Mixing with a Carrier Oil

One of the most common ways to use rosemary oil for hair growth is by mixing it with a carrier oil, such as coconut or jojoba oil. This diluted mixture can then be applied to the scalp and left on for an hour before washing.

10.2. Blending into Shampoo or Conditioner

Another convenient method is to add rosemary oil to your regular shampoo or conditioner. This allows you to reap the benefits of the oil while washing your hair.

10.3. Using Rosemary Oil Products

For those who prefer not to mix their own hair care concoctions, there are a multitude of rosemary-infused hair products available in the market. These products offer a hassle-free way to incorporate rosemary oil into your hair care routine.

11. Conclusion

While rosemary oil for hair growth shows promise, it's important to remember that results can vary from person to person, and it's not a guaranteed solution for everyone. However, its potential benefits and natural properties make it a worthy addition to a holistic hair care routine. As always, it's advisable to consult with a healthcare professional before starting any new treatment regimen.
