I’m sure we’ve all tried various DIY hacks in hopes of making our hair grow faster. Personally, I’ve experimented with rice-water treatments, aloe vera scalp massages, and castor oil products. But my latest venture is rosemary oil for hair growth.

After consulting with dermatologists and trichologists, it seems that rosemary oil may indeed have some benefits for hair and scalp health, and it might even help stimulate hair growth. Let’s dive into the details straight from the experts.

What is rosemary oil?

Rosemary oil is extracted from the leaves of the rosemary plant, which is native to the Mediterranean. You probably recognize rosemary as the fragrant herb that you use to season your food or even garnish your cocktails. It is also known for its use in fragrances, skincare products, and haircare products due to its potential to reduce inflammation.

When shopping for rosemary oil hair products, you might come across terms like “rosemary extract,” “rosemary essential oil,” or simply “rosemary oil” on the labels. These terms are used interchangeably, although they do have slight differences. Rosemary extract is the most potent form, while rosemary essential oil is diluted to some extent. Generally, rosemary oil refers to the essential oil mixed with a carrier oil like sweet almond or jojoba oil.

Is rosemary oil good for hair growth?

Rosemary oil, whether it is the essential oil, extract, or diluted version, has the potential to promote hair growth. There have been studies conducted on mice that showed promising results in re-growing hair affected by hormone-related hair loss. Additionally, a study compared rosemary oil to minoxidil (the active ingredient in Rogaine) and found that both showed similar levels of hair growth. However, it’s important to note that many dermatologists recommend a higher concentration of minoxidil for hair loss treatment.

Benefits of rosemary oil for hair growth:

Rosemary oil offers several benefits that may contribute to hair growth. The main ingredient, carnosic acid, has been shown to potentially stimulate and heal nerve tissue, which could have a similar effect on the scalp and encourage hair growth. Other compounds in rosemary oil, such as α-Pinene, 1,8-cineole, camphor, and borneol, are believed to have anti-inflammatory, antifungal, antibacterial, antioxidant, and pain-reducing properties, according to a study.

Moreover, rosemary oil is thought to enhance blood flow to the hair follicles, promoting healthier hair growth. Its strong antioxidant properties help prevent cell damage caused by free radicals. Additionally, its anti-inflammatory properties make it beneficial for those experiencing hair loss or thinning due to stress or hormone fluctuations.

Are there any side effects of using rosemary oil for hair?

Rosemary oil is generally well-tolerated by most skin and hair types, with minimal negative side effects. However, if you are pregnant or breastfeeding, it is advisable to consult your doctor before using rosemary oil on your hair, as some components may have potential risks during pregnancy. It is always recommended to perform a patch test on a small area of skin before applying the oil to your entire scalp.

Can you use rosemary oil for hair loss?

Using rosemary oil for hair loss is generally safe and can potentially improve circulation on the scalp and encourage hair growth. It may also help prevent inflammation-based hair loss conditions. However, it’s important to remember that hair loss can have various causes, such as age, hormones, genetics, stress, environmental factors, or medications. Therefore, it’s important to consult with a doctor or dermatologist for a comprehensive approach to hair growth.

How do you use rosemary oil for hair growth?

There are a few different ways to use rosemary oil for hair growth, depending on the product you have. If you have rosemary oil mixed with a carrier oil, you can directly apply two to three drops onto your scalp and gently massage it in. Alternatively, if you have pure rosemary essential oil, you should dilute it with another oil or your shampoo before applying it.

However, making your own rosemary oil concoction can be tricky, as using too much oil can irritate sensitive skin. It may be best to opt for products already formulated with rosemary oil and follow the manufacturer’s instructions. You can find rosemary oil in shampoos, treatments, or deep conditioners.

How long does it take for rosemary oil to grow hair?

In a study that compared rosemary oil scalp treatments to minoxidil, it took six months for participants to notice hair growth. However, keep in mind that everyone’s hair growth journey is different, and results may vary. If you’re concerned about your hair loss and don’t want to wait several months, it’s advisable to consult with a dermatologist for faster and more effective treatments.

Who should avoid using rosemary oil for hair?

While rosemary oil can be used on all hair types, it may be too heavy for fine, thin, or low-porosity hair. People with such hair types might experience greasy roots or oily ends when using rosemary oil. If that’s the case for you, it’s best to avoid using any hair oil.

Do you need to dilute rosemary oil for hair?

If your rosemary oil is already mixed with another carrier oil, such as castor oil or jojoba oil, you don’t need to dilute it further. However, if you have pure rosemary essential oil, it’s important to dilute it with a carrier oil like grapeseed or coconut oil, or use it mixed with shampoo. Essential oils are highly concentrated and can irritate the skin, leading to dryness, flaking, or burning.

Can rosemary oil be applied directly to hair?

Rosemary oil can be applied directly to your hair strands without causing damage. However, if you’re looking for potential hair growth benefits, it’s recommended to massage the oil into your scalp. If you have fine hair, you may prefer to apply the oil before bed and tie your hair up while you sleep, rinsing it out with a clarifying shampoo in the morning. Alternatively, you can apply the oil during the day, massage it in, and style your hair in a sleek bun for a greasy look.

Is it safe to use rosemary oil on hair every day?

For most people, it is safe to use rosemary oil on the hair and scalp every day. However, it’s essential to patch-test the oil first to ensure you don’t have any sensitivities. Those with high-porosity hair that absorbs oils more easily can even apply rosemary oil twice a day. If you have acne-prone or oily scalp, it’s best to limit usage to every couple of days to avoid clogging hair follicles and excessive hair washing.

Can you leave rosemary oil in hair overnight?

Yes, leaving rosemary oil on your hair and scalp overnight is perfectly fine. However, if you tend to have buildup or an oily scalp, it’s recommended to wash it out in the morning. You may need to use a clarifying shampoo to thoroughly cleanse your hair. If you prefer not to deal with washing it out, you can massage your scalp with rosemary oil 10 to 15 minutes before showering and then follow your regular shampoo and conditioner routine.

In conclusion, rosemary oil may be a promising option to consider if you’re dealing with hair loss, thinning, or a dry and itchy scalp. While there is some evidence suggesting its benefits for hair growth, more research is needed to confirm its effectiveness. Remember, hair growth is a complex process, and it’s important to consult with a medical professional if you’re experiencing significant hair loss.
