Looking for a natural way to support stronger, longer, and healthier hair?

Whether you’re dealing with breakage, thinning, or just want to give your hair a natural boost, this simple serum is a great addition to your weekly hair care routine. Made with argan oil, nettle, and rosemary — plus essential oils if you’d like to personalize it — it’s deeply nourishing, especially when massaged into the scalp and ends of your hair.
Hair Growth Oil Recipe
For this DIY, you will need argon oil, nettle, rosemary, and optional essential oils.

Place a small handful each of dried rosemary and dried nettle into a clean glass jar (a pint-size jar works well).
Pour enough argan oil over the herbs to completely cover them, leaving about ½ inch of space at the top.
Seal the jar and place it in a warm, sunny window for 2–4 weeks. Shake the jar every day or two to help the infusion process.
After the infusion period, strain the oil through a fine mesh strainer or cheesecloth into a clean bowl to remove the herbs.
Using a funnel, pour the infused oil into a clean dropper bottle.
Add up to 20 drops of essential oil to the infused oil and shake gently to combine.

To use: Place a few drops of the serum into your palms and rub together. Apply to the ends of your hair and work upward. You can also massage into the scalp to stimulate circulation. Use a few times a week or as desired.
How These Ingredients Support Hair Growth
- Argan Oil: Rich in vitamin E, fatty acids, and antioxidants, argan oil deeply moisturizes the scalp and hair. It helps reduce breakage, improves elasticity, and adds a healthy shine to dull strands.
- Nettle (Urtica dioica): Nettle is packed with silica, sulfur, and vitamins A and C — all of which strengthen hair, improve scalp health, and can reduce hair shedding.
- Rosemary: A legendary herb for hair growth, rosemary boosts circulation to the scalp, which may help stimulate hair follicles and promote growth. It also has anti-inflammatory and antioxidant properties that support a healthy scalp environment.
- Essential Oils (Optional):
- Lavender oil can promote hair growth and soothe the scalp.
- Rosemary oil is known to encourage new hair growth and improve cellular generation.
- Other options include peppermint, cedarwood, or tea tree for additional scalp benefits.
Substitutions & Customizations
- Carrier Oil Alternatives: If you don’t have argan oil, try jojoba, sweet almond, or olive oil. All are nourishing and scalp-friendly.
- Fresh Herbs Instead of Dried: You can use fresh rosemary and nettle, but be sure they’re completely dry to avoid mold in your oil. Dried herbs are safer for long infusions.
- Faster Infusion Method: Short on time? Use a double boiler on low heat to warm the oil and herbs for 1–2 hours. Let cool and strain.
- Essential Oil Variations: Swap lavender and rosemary with cedarwood, peppermint, or ylang-ylang for different benefits and scents.
Frequently Asked Questions (FAQ)
How often should I use this hair serum?
You can use it 2–3 times a week on the ends or scalp. For very dry or damaged hair, it can be used more often.
Can I leave this serum in overnight?
Yes! Apply it to your scalp and/or ends before bed, wrap your hair in a towel or use a shower cap, and wash it out in the morning.
Will this make my hair greasy?
A little goes a long way. Start with just a few drops and focus on the ends or massage into the scalp before shampooing. It should absorb well if used in small amounts.
How long does the infused oil last?
When stored in a cool, dark place, your infused oil should last about 6–12 months. Always check for any off smells or cloudiness before using.
Can I use this serum on color-treated hair?
Yes — it’s gentle and nourishing, making it great for chemically treated or colored hair.
