How to Use Marula Oil for Hair: A Complete Guide
How to Use Marula Oil for Hair: A Complete Guide
How to use marula oil for hair comes down to restraint and placement. Warm two to six drops between your palms, press them through the bottom two thirds of damp or dry hair, and comb through. Keep it off the roots and off the scalp unless your scalp is genuinely dry. Marula is light, stable and rich in oleic acid, which makes it a fine finishing oil and a poor heat protectant.
Key takeaways
- Marula comes from the kernels of the African Sclerocarya birrea tree and is high in oleic acid.
- It is light and unusually stable, so it suits fine hair and keeps well for about a year.
- Use drops, not pumps, and keep it to the bottom two thirds of the length.
- It is not heat protection. Use a proper heat protectant before styling and oil afterwards.
- It reduces breakage and helps you keep length. It does not change growth at the follicle.
What is marula oil, and where does it come from?
Marula oil is pressed from the kernels inside the stone of the marula fruit, which grows on Sclerocarya birrea across southern and western Africa. The fruit itself is eaten and fermented, and the hard nut at its centre holds one or two oil-rich kernels. Most cosmetic marula oil is cold pressed in southern Africa, frequently through women's cooperatives, which is part of why it carries a premium over commodity oils.
Its character comes from its fatty acid profile. A 2023 characterisation of marula seed oil published in Phytochemical Analysis confirmed what smaller studies had reported: the oil is dominated by oleic acid, typically around 70 to 80 percent, with much smaller amounts of palmitic, stearic and linoleic acids. That high monounsaturated share is why it feels light, absorbs quickly and resists going rancid, and it is the single most useful fact about the oil.
Why the oleic acid share matters
Polyunsaturated oils such as hemp and grapeseed oxidise quickly and need refrigerating. Monounsaturated oils such as marula and argan are far more stable, so they keep well, smell better for longer and are less likely to irritate skin as they age.
What does marula oil actually do for hair?
Three honest benefits, all of them cosmetic and all of them about the surface of the hair. It coats the cuticle so strands slide past each other rather than catching, which shows up as easier combing and less snapping during detangling. It helps the cuticle lie flat, which is what reduces frizz and produces shine. And on damp hair it slows moisture loss as the hair dries, so the finished result feels softer.
What it does not do is repair damage. Once the cuticle is chipped or the cortex is compromised by bleach or heat, no oil rebuilds it. What an oil does is make damaged hair behave better while the oil is on it, which is genuinely worth having but is cosmetic rather than structural. The only permanent fix for badly damaged ends is scissors.
The wider research on oils and hair supports the friction argument rather than any repair claim. A study in the Journal of Cosmetic Science measured protein loss from washed hair and found that oils applied before washing reduced it, with coconut oil performing best because its lauric acid can move into the fibre. Marula's larger oleic acid molecules mostly stay on the surface, which is exactly what you want from a finishing oil and not what you want from a pre-wash one.
How to use marula oil for hair, step by step
There are two ways of applying it worth knowing, and they solve different problems. Neither involves the roots.
On damp hair, for softness and frizz control.
- Patch test on your inner forearm 24 hours before the first use.
- Towel-blot until hair is damp rather than dripping. Oil will not spread evenly through sopping hair.
- Warm two to six drops between your palms depending on length and thickness.
- Press your palms over the bottom two thirds of your hair, then rake through with your fingers.
- Comb with a wide tooth comb from the ends upward to distribute it.
- Air dry, or apply a separate heat protectant before any dryer or iron.
On dry hair, for shine and flyaways.
- Use one or two drops only. This is the step people most often overdo.
- Rub between your palms until they feel barely oily.
- Smooth over the surface of the hair and the ends, not into the roots.
- If your hair looks greasy, you used too much. A dry shampoo at the roots will rescue it.

How much should you use, and how often?
Most of how to use marula oil for hair well is judging the amount. Frequency depends far more on your hair's thickness and porosity than on any schedule. Fine hair usually wants marula two or three times a week at most, and only on the ends. Medium hair tolerates every wash. Coarse, curly or coily hair can take it daily, and often benefits from it on damp hair every morning.
| Hair type | Amount | How often | Where |
|---|---|---|---|
| Fine, straight | 2 to 3 drops | 2 to 3 times a week | Ends only |
| Medium, wavy | 4 to 6 drops | Every wash | Bottom two thirds |
| Coarse, curly | 6 to 8 drops | Daily on damp hair | Mid lengths and ends |
| Coily, high porosity | 8 drops or more | Daily, over a leave-in | All lengths, scalp optional |
One structural point that saves a lot of disappointment: oil is a sealant, not a moisturiser. It slows water leaving the hair, it does not put water in. On very dry hair, apply a water-based leave-in conditioner first and the oil on top of it. Oil straight onto parched hair seals the dryness in.
Camellia & Black Castor Hair & Body Oil £24.95
A blend of black castor and camellia oils for hair, scalp and body. Heavier than marula, which makes it the better choice when coarse or coily ends need real sealing rather than a light finish.
Does marula oil protect hair from heat?
No, and this is the most important safety point on the page. There is a persistent belief that because some oils have a high smoke point in a frying pan, they must shield hair from a straightener. Cooking chemistry and hair are not the same problem. A thin film of plant oil provides no meaningful thermal barrier, and because oil conducts heat, it can transfer more of a hot plate's energy into the fibre rather than less.
The correct order is a heat protectant formulated for the job onto damp hair, then dry or style, then a drop or two of marula on the cooled ends for shine. That sequence gets you the finish without the risk. Our guide to the four causes of hair damage sets out how much of everyday damage is heat related, and the habits that prevent split ends covers what to do once the ends have already gone.
Protect Me® Heat Protection Spray £13.95
A leave-in heat protection spray rated to 230 degrees, with colour protection and frizz control. This is the product that goes on before the dryer or irons. The oil goes on afterwards.
How does marula compare with argan and coconut?
Marula and argan are close relatives in behaviour, both oleic-acid dominant finishing oils that smooth the cuticle. Marula is a touch lighter and more oxidation resistant, argan has decades of use in hair care behind it and is usually cheaper. Anyone claiming a dramatic difference between the two is selling one of them. Our piece on what argan oil really does applies almost unchanged to marula.
Coconut oil is the genuine outlier, and the one with the best evidence, because lauric acid is small and straight enough to move into the fibre and reduce protein loss during washing. It is also heavier and can leave fine hair stiff or straw-like, and a minority of people find it makes their hair feel worse over time. The sensible conclusion is that coconut is the pre-wash oil, and marula is the after-wash one. They are not competing for the same job.

Hair loss, hair shedding or hair breakage: what an oil can change
An oil is the right answer to exactly one of these, and knowing which saves both money and months.
Hair loss is a follicular problem. Pattern thinning miniaturises hairs over years and alopecia areata involves the immune system attacking the follicle. Neither is affected by anything applied to the outside of a hair fibre. A widening parting, a receding hairline or discrete patches should go to a GP rather than to a shelf of oils.
Hair shedding is a cycle problem. In telogen effluvium an unusual number of hairs move into the resting phase after illness, childbirth, surgery, sharp weight loss or acute stress, and release two to three months later. It resolves when the trigger is dealt with, and iron and thyroid checks are the useful first step. Oil is irrelevant either way.
Hair breakage is a fibre problem, and it is the one marula genuinely helps. Less friction means less snapping during combing and styling, which means more of the hair you grow stays attached. If you are finding short broken pieces rather than full-length hairs, and your length seems stuck, this is where the gains are, and it is the honest reason to learn how to use marula oil for hair properly. The four step routine for dry hair is the natural next read.
Masque Me® Repairing Hair Mask £24.95
An 8-in-1 deep conditioning mask for the weekly step. Where marula smooths the surface, a mask puts conditioning agents and hydrolysed proteins into dry, porous lengths.
Frequently Asked Questions
How much marula oil should I use?
The first rule of how to use marula oil for hair is to use less than you think. Two to three drops for fine or short hair, four to six for medium, and up to eight for long or coarse hair. Start with less than you think you need, because marula spreads further than heavier oils and you cannot take it back out without washing. Warm it between your palms first so it distributes evenly instead of landing in one greasy patch.
Should I apply marula oil to wet or dry hair?
Damp hair for softness and frizz control, dry hair for shine and flyaways. On damp hair the oil helps slow water loss as the hair dries, which leaves it softer. On dry hair it sits on the surface and smooths what is already there. Most people get the best result using a little on damp hair and one drop on dry ends afterwards.
Is marula oil good for fine hair?
Yes, it is one of the better choices. Marula is lighter than castor, olive or coconut oil and absorbs quickly, so it is less likely to flatten fine hair. The rule is still to keep it to the bottom two thirds of the length and to use drops rather than pumps.
Does marula oil protect hair from heat styling?
No, and this is a genuinely risky misunderstanding. Plant oils have no meaningful thermal barrier effect, and some can conduct heat into the fibre. If you are blow drying or using straighteners, use a product formulated as a heat protectant, and apply any oil after the heat rather than before it.
Does marula oil go rancid quickly?
Less than most. Marula is dominated by oleic acid, a monounsaturated fat, and contains natural antioxidants, which together make it unusually stable compared with polyunsaturated oils such as hemp or grapeseed. Kept away from heat and sunlight, a bottle will comfortably last a year.
Can I use marula oil on my scalp?
You can, but there is usually little reason to. Marula is a finishing oil for the lengths. If your scalp is dry and tight, a short pre-wash massage with a small amount is fine, but if you get greasy quickly, leave the scalp out of it entirely. Persistent flaking, itching or soreness is worth a pharmacist or GP visit rather than another oil.
Is marula oil better than argan oil?
They are close cousins and the honest answer is that the difference is small. Both are oleic-acid rich finishing oils that smooth the cuticle and add shine. Marula is slightly lighter and more stable, argan has a longer track record in hair care. Choose on texture, price and smell rather than on any claimed superiority.
Will marula oil help my hair grow?
No oil changes growth rate, because growth happens at the follicle and oil sits on the fibre. What marula can do is reduce the friction, dryness and snapping that stop you keeping the length you grow. For a lot of people that is the difference between hair that gains length and hair that seems stuck, but it is not the same thing as faster growth.

The Bottom Line
Marula is one of the better finishing oils available, and knowing how to use marula oil for hair is mostly about using less of it than you expect. A few warmed drops through the bottom two thirds of damp hair, combed through, gives softness and shine without weighing the roots down. Keep it off the scalp unless your scalp is dry, put a real heat protectant on before styling and the oil on afterwards, and layer it over a leave-in if your hair is very dry. It will help you hold the length you grow, which is a smaller and more honest promise than the label usually makes.
