Hair loss and thinning can be frustrating, and many people turn to expensive shampoos and chemical treatments hoping for results. But nature offers us a simple, effective, and affordable solution: rosemary. For centuries, this aromatic herb has been used to strengthen hair, stimulate growth, and keep the scalp healthy. Modern research confirms what tradition has long suggested — rosemary oil can encourage hair regrowth by improving circulation and nourishing hair follicles. The good news? You don’t need to buy pricey essential oils. You can make rosemary oil at home with just two ingredients and a little patience.

Why Rosemary Oil Works for Hair Growth
- Stimulates circulation: Increases blood flow to the scalp, feeding hair follicles.
- Reduces shedding: Strengthens roots, helping hair stay in place longer.
- Fights dandruff and irritation: Keeps the scalp healthy and balanced.
- Protects hair from thinning: Rich in antioxidants that shield against damage.
How to Make Rosemary Oil at Home
This is the foundation of the method. You’ll create an infused rosemary oil that anyone can make in their kitchen.
Ingredients:
- 1 cup fresh rosemary sprigs (washed and fully dried) or ½ cup dried rosemary
- 1 cup carrier oil (olive oil, coconut oil, or jojoba oil work best)
- A clean glass jar with lid
- A strainer or cheesecloth
- A dark glass bottle for storage (optional but recommended)
Step 1: Prepare the Rosemary
- If you’re using fresh rosemary, rinse it thoroughly to remove dust or dirt.
- Lay it out on a clean towel and allow it to dry completely — ideally overnight. (Moisture can cause mold inside the oil, so this step is important.)
- If using dried rosemary, you can skip this step.
Step 2: Combine Rosemary with Oil
- Place the rosemary into the glass jar.
- Pour in the carrier oil until the rosemary is fully submerged.
- Close the lid tightly.
Step 3: Infuse the Oil
You have two methods to choose from:
Slow Method (Best for Stronger Oil):
- Place the jar in a warm, sunny window.
- Let it infuse for 2–4 weeks, shaking the jar gently every couple of days.
- The longer it sits, the more potent the oil will be.
Quick Method (Ready in Hours):
- Place the rosemary and oil in a small saucepan or double boiler.
- Warm over the lowest heat for 3–4 hours. Do not let it boil.
- Allow to cool completely before straining.

Step 4: Strain and Store
- Once infused, strain the oil through a cheesecloth or fine strainer to remove the rosemary.
- Transfer the oil into a clean, dark glass bottle to protect it from light.
- Store in a cool, dry place. Properly stored, it can last up to 6 months.
