If you look in your spice cabinet, you’ll likely see rosemary leaves. This fragrant herb has a peppery and energizing essence, adding a little zing to whatever dish it’s in. But did you know that it’s also a versatile beauty ingredient?

You read that right. Rosemary essential oil is actually known for its antioxidant and anti-inflammatory properties. It’s said to aid in hair growth, hair thickening, soothing dry scalps, and preventing hair breakage. But how does it work—and more importantly, how can we use a rosemary oil product in our haircare routine? We turned to an expert for all the details.

What Are the Benefits of Rosemary Oil for Hair

“Rosemary oil is a plant-based ingredient that can help the overall health of your hair and scalp due to its anti-inflammatory properties,” says Annagjid “Kee” Taylor, a Philadelphia-based celebrity hairstylist and beauty entrepreneur. According to Kee, rosemary has some pretty impressive benefits. 

Aside from soothing an irritated or dry scalp, rosemary oil can:

  • Stimulate hair regrowth and repair breakage if you having thinning hair

  • In certain cases, it can aid in hair regrowth from alopecia areata and androgenetic alopecia

  • Improve blood circulation to scalp and hair follicles, allowing them to remain healthier overtime

  • Prevent dandruff

  • Relieve stress when used in aromatherapy

Are There Any Side Effects?

As with all new beauty products and ingredients entering your routine, you should always patch-test before completely diving in. In the case of essential oils, they need to be diluted with water or a carrier oil instead of using them on their own.

When not diluted, you can run the risk of burning your skin and compromising its barrier. If you’re struggling with dandruff and scalp irritation that has resulted in broken skin, consult your dermatologist before using new essential oils in your routine.

“You actually shouldn’t put rosemary oil directly onto your scalp as it could make it overly sensitive or irritated. You’ll want to mix it with a few other ingredients such as argan, sweet almond, or jojoba oil to act as a carrier for the rosemary,” says Kee.

The great thing about buying a product containing rosemary essential oil, or rosmarinus officinalis, is that it’s ready to use immediately—you won’t have to dilute or prep anything.

How to Use Rosemary Oil

In order to experience the full benefits that rosemary oil has to offer, you should aim to incorporate it into your hair care routine weekly, or even daily, if you can. Consistency is especially important if your goal is to target hair regrowth.

As Kee mentioned, you can mix rosemary oil with other oils that will act as a carrier within the treatment. For a DIY approach, you can use coconut oil, jojoba oil, castor oil, or pumpkin oil for hair regrowth and breakage.

For a detoxifying or soothing scalp treatment, you can blend with peppermint oil, lavender oil, or tea tree oil. You’ll want to do these as leave-in, overnight treatments.

Besides these ideas, you can add rosemary essential oil to your existing shampoo, conditioner, or hair mask. There are also plenty of hair products on the market already containing rosemary oil in their list of ingredients.
