How to dilute rosemary oil for hair.
The grave mistake in question? Using pure rosemary essential oil on your scalp. See, rosemary oil is an essential oil, and it is highly potent (like many other EOs), so it may actually irritate the skin when used on its own. As any expert will warn you: Never use straight-up essential oils directly on your skin or scalp.
We expect this is the reason some users have reported their hair falling out after using rosemary oil for a few months. Here’s the deal: Your scalp needs to be in a healthy, calm state for your strands to grow, and irritation is one way to disrupt a healthy scalp microbiome. Not to mention, constant irritation can lead to scalp inflammation, which can result in hair loss if left untreated.
That said, just dilute your formula to reverse the issue. Here are three easy ways to do it:
1.
Make your own scalp treatment.
First, pick your base oil. A few great options include jojoba, argan, or coconut oil (more here if you want to explore your options). Then in a dropper bottle, add anywhere from three to 15 drops of rosemary oil, depending on the size of your carrier container—the larger the size, the more rosemary oil you can use.

2.
Add it to a pre-formulated hair product.
If you have a hair oil or scalp serum you already love, it might be easier to add rosemary oil to that product as is. Go with the same ratio as above, and use your new supercharged scalp treatment as a daily boost or as the first step in your hair slugging ritual.
If you want to shake things up, you may consider a rinse as opposed to a traditional oil. Here’s how to make one:
- Pour 5 cups of water into a large pot. Drop in 5 sprigs of rosemary (1 sprig for each cup of water), and turn the heat on medium-high. Let the water come to a boil.
- Once you have a rolling boil, leave the mixture for 15 minutes.
- After 15 minutes, turn off the heat and then let it sit for another 25 minutes.
- Strain the mixture and pour the liquid into a jar. Store at room temperature away from sunlight and use within 3 months for the best results.
