DIY Rosemary Oil Serum Recipe And Benefits For Hair Growth

Amara Iwuoha
Rosemary oil serum is great for your hair because it contains natural compounds that stimulate hair growth, improve scalp health, and strengthen hair follicles. Here’s a breakdown of why it’s so beneficial:
1. Stimulates Hair Growth
Rosemary oil improves blood circulation to the scalp, which helps deliver more nutrients to hair follicles.
Studies have shown that rosemary oil can be as effective as minoxidil (a common hair regrowth treatment) in promoting hair growth without the side effects.
2. Prevents Hair Thinning & Balding
- It helps prevent DHT (dihydrotestosterone)-related hair loss, a common cause of androgenic alopecia (pattern baldness).
3. Strengthens Hair Roots
Regular use helps fortify hair at the roots, reducing breakage and shedding over time.
4. Reduces Scalp Inflammation & Dandruff
Its anti-inflammatory, antibacterial, and antifungal properties help calm irritated scalp and keep dandruff under control.
5. Improves Shine and Texture
When mixed with nourishing carrier oils (like jojoba, castor, or argan), rosemary oil smooths the hair cuticle, making hair softer, shinier, and less prone to frizz.
6. Balances Scalp Oil Production
It helps normalise oil production, making it beneficial for both dry and oily scalps.
Here’s a simple and effective DIY rosemary oil serum recipe designed to support quick hair regrowth, strengthen strands, and improve scalp health.
Ingredients:
- 2 tablespoons fresh or dried rosemary
- Carrier oil 100ml (choose one or mix):
- Jojoba oil (balances scalp)
- Castor oil (boosts thickness)
- Coconut oil (deep hydration)
- Argan oil (for frizz + shine)
- 1 teaspoon vitamin E oil (optional but helps nourish scalp + extend shelf life)
- Rosemary essential oil (optional but adds a punch) – 5–10 drops
- Dropper bottle (preferably dark glass to preserve oils)
Instructions:
- Wash and dry the dropper bottle thoroughly.
- Pop the rosemary into a saucepan, pour in your carrier oil and heat it up on low for about 20 – 30 minutes. Don’t let it boil.
- Once the oil has cooled down, strain out the rosemary leaves using a fine strainer or muslin cloth.
- Add the rosemary essential oil drops (about 10 –15 drops).
- Add vitamin E oil for extra nourishment and shelf life (optional).
- Combine everything by shaking the bottle gently and your magic oil is ready for use.
How to Use:
- Scalp treatment (2–3x per week):
- Part your hair and apply a few drops directly to the scalp.
- Massage in circular motions for 3–5 minutes to boost blood flow.
- Leave it on for at least 30 minutes or overnight for deep conditioning.
- Wash with a gentle, sulfate-free shampoo.
- Daily ends treatment (optional):
- Rub 1–2 drops between your palms and apply to hair ends to reduce breakage and split ends.
