Easy Rosemary Hair Growth Spray

I’ve talked a little bit about my postpartum hair issues in this post, but one way that I’ve been counteracting my thinner hair is with a rosemary essential oil hair growth spray.

Rosemary essential oil helps your hair grow faster and can even lead to thicker/fuller hair, so it was a great way for me to support my thinner hair (and help my awkward hair growth areas grow out faster).

This study showed that rosemary essential oil worked just as well as a leading hair growth drug without some of the side effects that the drug produced in users. I think it’s such a cool finding to be able to go a more natural route (with even better results) than a drug.

Anyway, here’s the easy recipe for rosemary hair growth spray that I’ve been using in case you want to try it for yourself!

-10 drops rosemary essential oil
-1/2 teaspoon Solubol or a carrier oil
-4 ounces distilled water
4 ounces spray bottle (amber bottles like this will keep the essential oil potent longer)
mini funnel (optional but helpful)

Add 10 drops of rosemary essential oil to a 1/2 teaspoon and fill the rest of the teaspoon with Solubol or a carrier oil.

Pour your oils into your bottle and fill the rest of the bottle to the top with water.

Give your bottle a shake and spray directly into roots and then rub it in with your fingers a bit. It makes my hair look a little wonky when it dries (it kind of gives it that wet look even when dry), so I tend to do it before bed and then fix my hair again the next day.

Spray into hair once a day. It’s true that it’s a little hard to tell for sure how much this works unless you only did it on half your head and compared it to the half you didn’t do it on, but I will say that I have always had trouble growing out my hair and I definitely noticed it growing way faster than usual.

How Long Does It Take to See Results?

This study says that the results were much more visible six months after starting treatments versus three months in, so I would stick with it a bit before giving up if you don’t see a difference right away.

And with any essential oil recipe, stop using it if you notice any adverse reactions.

Hope this simple recipe helps your hair look its best, too! xo. Laura

  • What are some other carrier oils that can be used? Would witch hazel or fractionated coconut oil work?

  • Thank you for providing clinical evidence for a product and not just anecdotes. It looks like this was first posted 2 years ago. Are you still using it daily? Seems like 2 years is a good long time to trial something. (Apologies if I missed that in the post.)

  • Thanks for this recipe! I’ve recently started using rosemary oil in jojoba to massage into my scalp but that leaves my hair oily and needs to be washed out, so I like the idea of a more water-based spray that can be used every day.
    Any idea how long this mixture will keep without going bad? Should it be kept in the fridge? I’m considering using Vitamin E as the carrier oil as it can act as a preservative.

    • I’ve seen that sprays like this will last around 6 months without being in the fridge, but if it starts to smell different (or not smell much at all anymore) I would make a fresh batch

  • The concentration of rosemary oil is too low. The study you cited used 2% rosemary oil, which equates to a 1/2 teaspoon per 4 oz, which is about 15-16 drops from my rosemary oil drip bottle. Then add to the carrier oil and mix with the water.

  • You can make a spray or put drops of rosemary essential oil straight into your shampoo bottle. I’ve used the oil straight into my shampoo bottle, probably about 6-8 drops for the average size bottle. I hope this helps as well!

  • I know you haven’t been using this that long so you may not have an answer… BUT, Do you know if it has “reverse” effects? Like if I use it for a year, then stop using will my hair thin back out?

  • This looks fairly simple. Thanks for the recipe Laura. Now, let’s see how much I can grow 😀

  • Well, at least your hair smells good, right? That could also be a reason to try this. My hair grows like crazy, so I don’t have to use this for hair growth.


  • This is what I use on my hair fresh Rosemary, but instead of the essential oil I soak fresh Rosemary in Extra Virgin Olive Oil and let it draw out the Rosemary naturally for about 1 month, until you can smell the Rosemary scent…fyi I also use the oil to cook with.

    lso use it to cook with.

  • I definitely need to try this! I feel as though my hair has been falling out a bit recently, so that will definitely come in handy. Thanks for sharing, hope you are having a great day!!


  • I will give this a try for sure my hair is so bad that I no longer put it up there spot’s that there really not much hair am 62 and just this year I started dating thanks

  • hmmm very intriguing. my boo thinks he’s balding so i might make some for him. love that it’s a natural solution! i wrote a low waste hair care post this way if anyone is interested: https://tps-steph.blogspot.com/2019/02/0029-tps-low-waste-haircare.html

  • Love the idea of an all natural anything that works; I’ll try it on my already maturing fine hairline and temples ; thanks for the info; Claudia..C

  • Hello. Im searching for a hair growth serum, my hair is thin, it used to be thick & fulll. How can i order your serum?

    • Hi! It’s a DIY. We don’t sell it, but you can use the instructions to make your own. 🙂

  • Gonna give it a try, fingers crossed that it’ll work. I’ve always had thick hair and no problems whatsoever. My hair grows, but it is so thin. And lays flat on my head

  • Thanks for sharing this recipe – I wish I had found this when I was experiencing hair loss after stopping taking my contraceptive pill. However in hindsight, that hair loss was nothing compared to post partum hair loss! I am currently using a chemical spray which is working very well but I might try this too – it can’t hurt can it?!?

    • what name of the of the chemical productor you using.? please

  • Hey, have you tried using a microneedler with the rosemary oil as well? I’ve used it and it improves the results vastly. The same thing goes with using a microneedler with rogaine. You can google the study that was done, it’s on the NCBI website. There’s also PRP treatment which works great that’s I’ve done

  • Wow, I do hope this works! Sounds like a great natural solution to a problem many struggle with!

  • I have a ton of fresh rosemary. What would be the recipe for fresh rosemary.

    • Hi!
      I don’t have a recipe for that, the rosemary essential oil is super concentrated so I have no idea how you would be able to extract the same amount from a live plant on your own, sorry!


    • Hi , i have fresh rosemary too , i put atleast 3-4 stem leaves in boiling water and turn the stove off. And i love the spray.

  • I’ve always struggled to find ways to grow my hair so I’m really hoping this helps! can’t wait to give it a try x

  • Hi Laura,
    Do you think this formula work on eyebrows as well? Do you use tap water or a purer form of water to mix in?

    • I would suggest distilled or filtered water for any sort of oil blend mixture that won’t be used within a day or two, there are impurities in tap water that will make the blend go bad faster. As far as eyebrows go, I’ve seen lash and eyebrow serums that use rosemary oil so it would probably work but you’d want a small brush applicator rather than spraying a big spray onto your face (and you’ll want to avoid getting the spray directly in your eyes).
