Hair concerns like dryness, breakage, thinning, or scalp irritation can often be supported with the right oils, and there’s no shortage of options to choose from. Argan, coconut, jojoba, castor… each brings its own set of benefits. But among these, rosemary oil has quietly built a reputation as one of the most functional and versatile oils for hair care.
In this post, we’re not here to recommend specific store-bought brands mainly because what works for one hair type may not suit another, and the wrong product can often do more harm than good. Herein you can learn how to make rosemary oil for hair.
Can you make rosemary oil for hair at home
Yes, you can absolutely make rosemary oil for hair at home, and it’s much simpler than most people think. Fresh rosemary can be heated with a carrier oil like olive or jojoba for a quick, potent blend but keep in mind, because of the moisture in fresh herbs, this version has a short shelf life and should be used within a few days.
For something longer-lasting, dried rosemary offers a slower infusion option that can sit in a sunny window for a couple of weeks, gradually releasing its natural oils into your chosen base. Both methods allow you to create a nourishing treatment that supports scalp health and promotes hair vitality, all without synthetic ingredients or preservatives.
What’s required
Fresh or dried rosemary
This is the star ingredient. Rosemary contains beneficial compounds like rosmarinic acid and camphor, which are believed to stimulate circulation to the scalp and promote hair growth.
-
Fresh rosemary gives a strong, quick infusion but has a shorter shelf life due to moisture.
-
Dried rosemary is ideal for a slower infusion and lasts longer without the risk of going rancid.
Carrier oil (e.g., olive, jojoba, grapeseed, or sweet almond oil)
This is the base that absorbs the rosemary’s nutrients and makes the oil usable on your hair and scalp. The carrier oil you choose can also offer its own benefits, for example, jojoba closely mimics the scalp’s natural oils, while olive oil is deeply moisturizing.
Clean glass jar with lid
A sealed glass jar is essential for infusing your oil safely. Glass doesn’t react with oils the way some metals or plastics can, and it helps retain the oil’s purity. The jar keeps your ingredients protected from dust, air, and moisture during the infusion period.
Cheesecloth or fine mesh strainer
Once your oil is infused, you’ll need to strain out the rosemary leaves. A cheesecloth or fine strainer ensures you get a clean, smooth oil that’s ready for hair use without bits of herb left behind.
Small saucepan or double boiler (for quick method only)
If you’re doing the quick-heat version, warming the rosemary in oil allows the infusion to happen in under an hour. A double boiler is preferred to avoid overheating, which can destroy beneficial compounds in both the rosemary and the carrier oil.
Dark glass storage bottle (optional but recommended)
After straining, storing the finished oil in a dark amber or cobalt bottle helps protect it from light, which can degrade the oil over time. This is especially important if you’re planning to store your rosemary oil for several weeks.
Let’s make rosemart oil for hair
Step 1. Pick your rosemary
Choosing either fresh rosemary (for a quick, fragrant batch) or dried rosemary (for longer shelf life). Fresh gives a strong scent and faster infusion, but the moisture means you’ll need to use the oil quickly. Dried rosemary is more stable and ideal for slow infusion.
Step 2. Pour the oil
Select your carrier oil: olive for deep moisture, jojoba for light balance, or grapeseed if your scalp leans oily. Pour enough into a clean glass jar to fully cover the rosemary.
Step 3. Infuse it slowly (or fast!)
For a slow infusion, seal the jar and let it sit in a warm, sunny spot for 2–3 weeks. If you’re in a rush, use the quick-heat method: gently warm the oil and rosemary together in a saucepan over low heat for about 30 minutes, then cool completely.
Step 4. Strain the magic
Once the infusion is complete, strain out the rosemary using a cheesecloth or fine mesh strainer. This step keeps your oil smooth and easy to apply without any leftover herbs sneaking into your hair.
Step 5. Bottle it right
Pour the strained oil into a dark glass bottle to protect it from light, and store it in a cool, dry place. Your homemade rosemary oil is now ready to nourish your scalp, soften your strands, and become your new favourite part of wash day.
No patience? Try the quick heat method
If waiting two weeks for a slow infusion isn’t your thing, the quick heat method is a faster alternative that still delivers many of rosemary’s natural benefits.
Simply combine a few sprigs of fresh rosemary with your carrier oil of choice in a small saucepan or double boiler, and warm it gently over low heat for about 20 to 30 minutes.
Once the rosemary looks slightly crisp and the oil smells fragrant, remove it from the heat and let it cool completely. Strain out the herbs, and your rosemary oil is ready to use.
How to use rosemary oil for hair without turning into a greaseball
Using rosemary oil for hair doesn’t have to mean walking around with heavy, greasy roots, and the secret is all in how much you use and where you apply it. A few drops. Seriously, just two to three. are usually enough for a full scalp treatment. You can focus the oil on your scalp, not the lengths of your hair, and take a few minutes to gently massage it in with your fingertips to help stimulate circulation.
