To dilute rosemary oil for hair use safely and effectively, follow these expert guidelines:
Dilution Ratios
- Standard dilution: Mix about 2-3% rosemary essential oil with a carrier oil. This typically means adding 2-3 drops of rosemary oil per tablespoon (15 ml) of carrier oil
- For sensitive scalps: Use a lower dilution of around 1%, which is about 1 drop of rosemary oil per tablespoon of carrier oil to minimize irritation risk
- Common examples:
- 1 tablespoon (15 ml) carrier oil + 2-3 drops rosemary oil (2-3%)
- 2 tablespoons (30 ml) carrier oil + 4-6 drops rosemary oil
- 1/2 cup (120 ml) carrier oil + 16-36 drops rosemary oil (adjust accordingly)
Carrier Oils to Use
Choose a carrier oil that nourishes hair and scalp while diluting the rosemary oil potency:
- Jojoba oil (mimics scalp sebum)
- Coconut oil (deep conditioning)
- Argan oil (rich in antioxidants and vitamin E)
- Sweet almond oil (gentle and easily absorbed)
- Olive oil or grapeseed oil are also good options
How to Mix and Use
- Combine the rosemary oil and carrier oil in a clean container.
- Shake well to mix thoroughly.
- Perform a patch test on a small skin area before full application to check for sensitivity or allergic reactions
- Apply the diluted oil to the scalp using gentle circular massage motions to stimulate blood flow and enhance absorption
- You can also add the diluted oil to hair masks or use as a scalp treatment before washing
Summary
Diluting rosemary oil to about 2-3% concentration with a nourishing carrier oil like jojoba or coconut oil is ideal for most people. For sensitive scalps, start with 1% dilution. Always do a patch test and massage gently for best results and to promote hair growth safely
