Brooklyn Botany Rosemary Essential Oil - Huge 4 Fl Oz - 100% Pure and Natural - Premium Grade with Dropper - for Aromatherapy and Diffuser

And that was a good WOW. Honestly this is the strongest essential oil I've ever had and I have several. So, if you are looking for a rosemary that's seemingly real deal and down right only rosemary oil. Kinds you're most definitely going to need to mix with a carrier, and I don't have sensitive skin or anything, but it is stout. I use another oil that's a well known brand for hair and scalp. But it has many other oils mixed into it including hibiscus 🌺 coconut several others and it has a strong scent. But this one is way stronger( pure rosemary oil, in review) than that one. ! I'm going to bet that this is what you're looking for if it's a strong, long lasting and very fragrant rosemary. I feel like I got the real deal of what I was going after in a rosemary, and isn't diluted at all. This brand is most definitely the business and deserves the hyped review. I will be trying other flavors of this brand due to the consistency and great value I got for this, it's well worth the money and I hope they make lavender. Because in obsessed with it ATM. When I use this rosemary in my hair, OMG I add about 15 drops to around two table spoons of either avocado, carrot or coconut oil and sometimes I mix them all or and other carriers I pour it around the roots of my hair and on the scalp after mixing. And massaging into the scalp allowing it to also go down my hair as well, I will leave it all night but have left it only for a few hours as well, and when I wake and wash my hair the next morning. Let me tell you how beautifullu shiny my hair is. Ok I don't know if I've taken any photos lately of how shiny, smooth and silky it looks but I will come back and add some within a week from now. Just to show you guys how well it works in my hair. It's super strong. So, that's a bit concerning at first. Because the other stuff I used before doesn't hit me as hard as this brand. But I do believe it's legit so, I'm not as worried about it now as I was the first day I used it. But I assume rosemary is a strong scent in the first place. Just not as strong as this in my others. Anyways. This is real deal rosemary and you should try it if you're looking through all of the selections they've got. Which are tons. This one is very nice, and strong.

(EDIT: I contacted Brooklyn Botany to request the GC/MS test results, just to be sure. They sent me a copy, and it confirms that this oil is 100% undiluted and unaltered! Woohoo!) Before my review, a warning: Most essential oils on Amazon are diluted with cheap fillers, added fragrance, etc., and it's perfectly legal for companies to call diluted oils "100% pure". Fake or diluted oil is fine if you just plan to use it as fragrance, but if you want the specific benefits of the herb, you need the real deal. Look for sellers that do third-party testing (like this one!) to increase the likelihood that what you're getting is good quality. If you can afford higher-end brands, those are worth the cost, but if you're on a budget then this brand is a fantastic choice! You can see in my second photo that this oil is crystal clear, no off color or cloudiness. The smell is authentic & as potent as essential oil should be. I could smell it the moment I opened my package, to the point that I was worried it had leaked during shipping, but it's really just that strong! I'll be using it to make a hair oil with 3% rosemary + 97% carrier oil. That means this 1oz bottle can make a whole LITER of hair oil! I just mixed a little test batch at that strength and it still has a strong rosemary scent, which shows how potent this is.

This is a great product and it smells amazing. I leave the rosemary oil on my scalp overnight to stimulate growth. It doesn’t leave my hair greasy when I wake up. I have ordered it several times from this seller and have received it promptly each time. Thank you!

Decent essential oil, It pacaged well, has glass dropper. I use rosemary and peppermint oil on my hair. My scalp is able to tolerate it undiluted (don't risk it though). I am not consistent with it, however i see less hair on my brush and less scalp inflamation, dandruff, no new hair grow yet. The only downside is one of the bottle were impossible to open, So, I ended up demaging the lid. (See video). I suspect this due to bottle only have few month before expiration (delivered 12/31/2025 and expiration is 06/2026) it came together with lavander oil, that is good until 09/2027.

The smell is so overpowering. I use this with 4 other oils for my scalp and this alone smells so strong. It does the job, I just wish the smell wasn't so potent.

Good quality

Use this with my shampoo and helps with my itchy scalp. Smells wonderful to.

This essential oil is fabulous! I purchased both the lavender and the rosemary and both are exceptional. I love that they come with the dropper. Would definitely purchase again.

I’ve been using this rosemary essential oil for a few weeks now and I’m really impressed with the quality. The scent is strong, fresh, and very natural—just a few drops go a long way. I’ve been adding it to my diffuser, mixing it into my scalp oil for hair care, and even using it in DIY cleaning sprays. The bottle size is generous compared to most essential oils, so it feels like great value. It also comes with a dropper which makes it super easy to control how much you use without wasting any. If you love rosemary oil for hair, aromatherapy, or DIY products, this one is definitely worth adding to your collection. High quality and very versatile! 🌿✨

We bought it for regular use, and it’s been amazing so far. The smell is fresh, the quality feels pure, and a little goes a long way. Great for hair and everyday use — definitely worth it!

Excellent product and service. Thank you.

I won't say its best of quality. There are better quality available. Feels bit mild.

It’s great quality and you won’t be disappointed
