Walk into any beauty store in Lagos, Accra or Nairobi and ask for a hair growth oil, and you will probably be shown three options: batana oil, castor oil and rosemary oil. All three are popular, all three have loyal fans, and all three work in different ways.
This guide breaks down how they compare so you can choose the right one, or the right combination, for your hair.
Quick comparison
| Batana oil | Castor oil | Rosemary oil | |
|---|---|---|---|
| Source | American oil palm nut (Honduras) | Castor bean | Rosemary leaves (essential oil) |
| Texture | Thick, buttery | Very thick, sticky | Thin, watery |
| Main strength | Deep conditioning, less breakage | Sealing, thick-looking edges | Scalp stimulation |
| Key compounds | Oleic and linoleic acids, vitamin E (tocotrienols), carotenoids | Ricinoleic acid | Carnosic acid, rosmarinic acid |
| Research on growth | Limited, mostly traditional use | Limited | Most studied of the three |
| Use undiluted? | Yes | Yes | No, always dilute |
| Best for | Dry, coily, damaged hair; beards | Edges, brows, sealing ends | Thinning, slow growth |
Batana oil
What it is: A rich oil pressed from the nut of the American oil palm, traditionally made by the Miskito people of Honduras. Read our full guide to what batana oil is.
What it does well:
- Deeply moisturises dry, coily hair
- Reduces breakage, so you retain more length
- Supports a healthy scalp with antioxidants from the vitamin E family
- Makes hair and beards look fuller and shinier
Downsides: It is heavier than most oils and can weigh down fine or straight hair. Quality varies a lot between sellers.
Best for: Natural and 4C hair, breakage, thin ends, patchy beards and receding hairlines.
Castor oil
What it is: A thick oil from castor beans. Jamaican black castor oil (JBCO) is a roasted version that is darker and popular in natural hair routines.
What it does well:
- Excellent sealant for locking moisture into hair
- Popular for edges, eyebrows and lashes
- Coats hair heavily, making it look thicker
Downsides: It is very sticky and hard to spread on its own, and can be difficult to wash out. Some people find it makes their hair feel stiff.
Best for: Edges, brows, and sealing the ends of natural hair.
Rosemary oil
What it is: An essential oil distilled from rosemary leaves. It is very concentrated and must always be mixed with a carrier oil.
What it does well:
- Stimulates the scalp and circulation
- Has the strongest research behind it for hair growth: a small 2015 study found that rosemary oil performed similarly to 2% minoxidil for a type of hair thinning over six months
- Has a fresh smell and does not weigh hair down
Downsides: It can irritate the scalp if used undiluted or too often. It does very little to moisturise hair on its own.
Best for: Thinning hair and slow growth, used diluted in a carrier oil.
Which should you choose?
- Your hair is dry, breaking and not retaining length: Choose batana oil.
- Your edges or brows are thin: Choose castor oil or batana oil for nightly edge care.
- Your hair is thinning and you want scalp stimulation: Use rosemary oil, diluted.
- You want the best of everything: Combine them.
The power combo: batana + rosemary
Because batana oil is a nourishing base and rosemary oil is a stimulating active, they work well together:
- Melt 1 teaspoon of batana oil in your palms.
- Add 3–5 drops of rosemary essential oil.
- Massage into the scalp for 3–5 minutes.
- Leave on for at least 2 hours or overnight.
- Wash out with a gentle shampoo.
Use this 2–3 times a week. Our step-by-step guide on how to use batana oil for hair growth covers the full routine.
A note on expectations
No oil can override genetics, hormones or medical causes of hair loss. Oils work best when combined with good habits: gentle styling, fewer tight braids and glued wigs, sleeping on satin, a balanced diet and regular trims. If your hair loss is sudden or patchy, see a doctor or dermatologist.

Frequently asked questions
Which oil is best for hair growth?
Rosemary oil has the most research behind it for stimulating growth, castor oil is excellent for thickening the look of edges and brows, and batana oil is best for deep conditioning and length retention. Many people get the best results by combining them.
Can I mix batana oil and rosemary oil?
Yes. Add 3 to 5 drops of rosemary essential oil to a teaspoon of batana oil. Never apply rosemary essential oil undiluted to the scalp.
Is batana oil better than castor oil?
Neither is better in every case. Batana oil spreads more easily and is richer in antioxidants, while castor oil is thicker and very good for sealing and for edges. Choose based on your hair type and goal.
Which oil is best for 4C hair?
Batana oil and Jamaican black castor oil are both excellent sealants for 4C hair. Use either after a water-based leave-in to lock in moisture.
