If there’s one herb I always have growing on my windowsill or tucked in my garden, it’s rosemary. It smells heavenly, looks like a tiny evergreen tree, and is bursting with benefits. From making your scalp tingle in the best way possible to adding that rich, savory taste to your roasted root vegetables, rosemary’s truly a wonder herb. And the good news? You can easily make your own homemade rosemary oil right at home using just a few ingredients and a little patience.
In this post, I’ll show you how to make Homemade Rosemary Oil—a powerful, multi-use DIY rosemary oil that works for hair growth, skin nourishment, massage oils, salad dressings, and more. Whether you’re aiming to revamp your hair care routine or whip up a fragrant oil for cooking, this rosemary oil recipe is simple, potent, and made right in your own kitchen.
Why Rosemary Oil?
The health benefits of rosemary have been cherished for centuries. It’s packed with anti-inflammatory properties, antimicrobial properties, and it’s even shown potential in improving blood circulation, especially when massaged into the scalp. If you’re struggling with itchy scalp, hair loss, or thinning hair (hello, postpartum mamas!), rosemary-infused oil is a natural go-to.
It’s also been researched for helping with androgenetic alopecia, which is the scientific way of saying hormonal hair thinning. With regular use, rosemary hair oil can encourage blood flow to your hair follicles, helping breathe new life into your hair strands. It’s amazing how something as simple as rosemary and oil can bring so much nourishment, comfort, and joy into our homes.
Homemade Rosemary Oil Recipe
Here’s the easy way I make rosemary oil at home. It smells like a spa and works like magic.
Ingredients:
Method 1: Slow & Low (Stovetop or Slow Cooker)
1. In a small saucepan or slow cooker, combine your rosemary sprigs and cups of olive oil.
2. Simmer on low heat for 2–4 hours. Never boil! You’re looking for a deep green color and that signature piney scent.
3. Turn off heat and let it cool.
4. Strain using a fine mesh strainer into a glass jar.
5. Store in a dark place at room temperature for up to 6 months. That’s your shelf life!
Method 2: Sunny Infusion (For the Patient Ones)
- Place rosemary sprigs and oil in a glass jar.
- Set it on a sunny windowsill for 2–3 weeks, shaking every few days.
- Once infused, strain and store as above.
Tip: Want to use it in the kitchen? Use regular olive oil or treat yourself with a bottle from your local fancy olive oil shop for the richest depth of flavor.
Ways to Use Homemade Rosemary Oil
For Hair:
Massage a small amount into your scalp 2–3 times a week. It’s amazing for scalp health, hair growth, and even helping with certain scalp conditions. For a deeper treatment, apply to hair and let sit for 30 minutes before washing with natural hair products. (Don’t forget to do a patch test first if you have sensitive skin!)
For Skin:
Use it as a base for body oils, massage oils, or to soothe muscle pain. It’s also a lovely option for dry skin care routines, thanks to its nourishing essential oil compounds.
For Cooking:
Drizzle over roasted root vegetables, mix into salad dressing, or finish off meat dishes. It adds that savory taste you’d see raved about on the Food Network.
