What Can You Use Coconut Oil For: 20+ Uses

Coconut oil is one of those rare household staples that genuinely crosses categories, from cooking fat to hair treatment to insect repellent, with peer-reviewed research backing a surprising number of its uses. It is also surrounded by hype that outpaces the evidence, particularly when it comes to weight loss and sun protection. What follows is a practical rundown of more than twenty ways people use coconut oil, with honest notes on where the science is strong, where it is emerging, and where the claims fall apart.

Hair Protection and Deep Conditioning

One of the best-supported uses for coconut oil is as a hair treatment. A study comparing coconut oil, sunflower oil, and mineral oil found that coconut oil was the only one that reduced protein loss from hair, whether applied before or after washing, and whether the hair was damaged or undamaged.¹ The reason comes down to molecular shape: coconut oil is rich in lauric acid, a straight-chain fatty acid small enough to actually penetrate the hair shaft and bind to the internal protein structure. Sunflower oil, by contrast, has a bulkier molecular shape that keeps it sitting on the surface.

In practice, this means coconut oil works as a pre-wash treatment to limit damage from shampooing, a leave-in conditioner for dry ends, and a frizz smoother on damp hair. A little goes a long way. People with fine or low-porosity hair sometimes find it weighs strands down, so starting with a small amount on the ends and working upward is the safer approach.

Skin Moisturizer and Eczema Relief

Coconut oil is a genuinely effective moisturizer, and the evidence is strongest in mild to moderate eczema. A randomized double-blind trial in children with atopic dermatitis compared virgin coconut oil to mineral oil over eight weeks. The coconut oil group saw dramatically better results on both clinical severity scores and measurable skin hydration. Transepidermal water loss, a marker of how well the skin barrier is functioning, dropped from about 27 to 7 in the coconut oil group versus 24 to about 14 in the mineral oil group.² Skin hydration also improved more with coconut oil.

For general dry-skin relief on the body, arms, and legs, coconut oil performs well as an emollient. It forms a protective layer that slows moisture loss while the lauric acid offers mild antimicrobial benefits. Where you need to be more careful is on the face, which brings its own set of considerations covered below.

Cooking, Baking, and Deep Frying

Coconut oil has a smoke point around 175°C (about 350°F) for virgin and somewhat higher for refined versions, making it suitable for sautéing, baking, and moderate-temperature frying. Where it really shines is stability. During continuous deep frying, coconut oil produced the slowest increases in markers of oil degradation compared to sunflower oil and palm oil, and its trans fat content did not rise significantly.³ A separate comparison of refined coconut oil and palm olein found coconut oil held up better across multiple quality measures, including resistance to oxidation and lower buildup of polar compounds.⁴

Beyond frying, coconut oil works as a butter substitute in baking (it is solid at room temperature, which helps with pastry texture), a base for homemade granola or energy bites, and a greasing agent for pans. Its mild sweetness and coconut flavor pair naturally with Southeast Asian and Caribbean cuisines, curries, and tropical desserts. Refined coconut oil has a more neutral taste for people who want the cooking properties without the coconut flavor.

Oil Pulling for Oral Health

Oil pulling, swishing oil in the mouth for ten to twenty minutes, is an old Ayurvedic practice that has gained modern research attention. A preliminary study on coconut oil pulling found that both plaque levels and gingival inflammation scores dropped significantly starting from day seven and continued improving over the study period.⁵ Lab studies have also shown that coconut oil can reduce counts of the cavity-causing bacterium Streptococcus mutans at levels comparable to chlorhexidine mouthwash.⁶

That said, results are not unanimous. One randomized trial comparing virgin coconut oil pulling to palm oil pulling found no significant difference between the two for bacterial reduction, and the coconut oil group did not achieve a statistically significant drop in S. mutans from baseline.⁷ The honest picture is that oil pulling with coconut oil likely helps reduce plaque when used alongside normal brushing and flossing, but it is not a replacement for either. Think of it as a supplement to your routine, not a shortcut.

Wound Healing

Animal research suggests coconut oil speeds up wound repair. In a study on young rats, wounds treated with virgin coconut oil healed faster, showed higher collagen cross-linking, and had elevated levels of skin repair components compared to untreated wounds.⁸ The antioxidant activity of the oil also appeared to reduce oxidative stress at the wound site. Human clinical trials on wound healing are still limited, so the most reasonable use is applying coconut oil to minor cuts, scrapes, and dry cracked skin as a protective barrier while the skin heals on its own.

Fighting Acne-Causing Bacteria

This one comes with a strong caveat. Lauric acid, the main fatty acid in coconut oil, is genuinely potent against the bacterium responsible for inflammatory acne. Lab studies have found that lauric acid has stronger antibacterial activity against this organism than benzoyl peroxide, the most common over-the-counter acne treatment, with a minimum effective concentration more than fifteen times lower.⁹ When lauric acid was delivered in a liposomal form (tiny fat-based carriers), it killed acne bacteria both in the lab and on mouse skin by fusing directly with bacterial membranes.¹⁰

Here is the catch: coconut oil applied directly to acne-prone facial skin can clog pores, potentially making breakouts worse. The antibacterial benefits of lauric acid are real, but delivering them as raw coconut oil smeared on the face is not the same as the controlled liposomal formulations used in research. For acne specifically, lauric acid may eventually appear in targeted topical products, but slathering coconut oil on your face is a gamble if you are prone to breakouts.

When Coconut Oil Clogs Pores

Multiple recent studies have used coconut oil as a positive control for comedogenicity, meaning it is the substance researchers use when they need something they know will clog pores. One study measured a mean comedogenic grade of about 2.1 for coconut oil, compared to 0.8 for glycerin.¹¹ Another confirmed coconut oil as “highly comedogenic” with a similar grade of about 1.9.¹² A comprehensive review of plant-based cosmetic oils likewise noted that coconut oil is comedogenic and can trigger breakouts in people with sensitive or acne-prone skin.¹³

The practical takeaway: coconut oil is a fine moisturizer for your body, legs, elbows, and feet. On the face, it is a roll of the dice. If your skin is oily or acne-prone, use it elsewhere and choose a non-comedogenic facial moisturizer instead.

Head Lice Treatment

A coconut-and-anise spray has shown genuinely impressive results against head lice. In a randomized trial of 100 participants, the spray cured about 82% of infestations, compared to 42% for permethrin lotion, a standard pharmaceutical treatment.¹⁴ A separate clinical study using a blend of coconut oil, anise oil, and ylang ylang oil also found it highly effective under real-world conditions with no serious side effects.¹⁵ In lab tests, coconut oil also served as an effective carrier for essential oils like clove oil, which reached over 90% louse mortality within two hours.¹⁶

The mechanism appears to be partly physical (the oil coats and smothers lice) and partly chemical (the fatty acids and essential oils are directly toxic to the insects). For parents looking for a gentler alternative to pesticide-based treatments, especially in areas where lice have developed resistance to permethrin, a coconut-oil-based approach is worth trying.

Insect and Tick Repellent

Compounds derived from coconut oil fatty acids have performed remarkably well as insect repellents. A study published in Scientific Reports found that the medium-chain fatty acids from coconut oil repelled biting flies and bed bugs for two weeks after application, ticks for one week, and also worked against mosquitoes. The repellency was stronger and longer-lasting than DEET.¹⁷ These are processed coconut fatty acid fractions rather than straight coconut oil from a jar, so rubbing raw coconut oil on your skin will not give you the same protection. But the finding has driven interest in coconut-derived ingredients for next-generation repellent products.

Antimicrobial Properties Beyond the Skin

Lauric acid and its derivative monolaurin work by disrupting bacterial cell membranes.¹⁸ What makes this interesting from a gut health standpoint is that lauric acid appears to be selective. Testing against human gut bacteria found that it had low activity against beneficial lactic acid bacteria but high activity against potentially harmful species.¹⁹ This selective antimicrobial profile is preliminary but intriguing, and it partly explains why coconut oil has a long history as a folk remedy for digestive complaints in tropical regions.

The Cholesterol Question

Coconut oil’s effect on blood cholesterol is the most contentious area. A meta-analysis of 16 clinical trials found that coconut oil raised LDL cholesterol (the type cardiologists worry about) by roughly 10 mg/dL compared to other plant-based oils, while also raising HDL cholesterol by about 4 mg/dL.²⁰ A separate meta-analysis confirmed this pattern: LDL went up, HDL went up, and body weight, body fat, and inflammation markers stayed unchanged compared to non-tropical vegetable oils.²¹

An important nuance comes from a randomized trial that compared coconut oil head-to-head with butter and olive oil. Butter raised LDL significantly more than both coconut oil and olive oil, and coconut oil did not differ from olive oil in its effect on LDL. Coconut oil actually raised HDL more than either butter or olive oil.²² So coconut oil is not the cardiovascular villain it is sometimes painted as, but it is also not a health food. Using it in place of butter is probably a wash or slightly better. Using it in place of olive oil or other unsaturated plant oils nudges your LDL in the wrong direction. If you enjoy it for cooking or flavor, moderate use as part of a varied diet is the sensible approach.

Why It Is Not a Weight Loss Aid

A persistent claim online is that coconut oil boosts metabolism and helps you lose weight, usually based on research into medium-chain triglycerides (MCTs). The problem is that coconut oil is not the same thing as concentrated MCT oil. A study directly comparing the two found that MCT oil reduced food intake and increased feelings of fullness, while coconut oil performed no differently from a control oil on either measure.²³ The researchers concluded that coconut oil “cannot be promoted as having similar effects to MCT oil on food intake and satiety.”

Mouse studies have shown that coconut oil and medium-chain fatty acids can activate brown fat tissue and improve metabolic markers in animals on high-fat diets.²⁴ But mouse metabolism is not human metabolism, and these findings have not translated into reliable weight loss in people. Adding coconut oil on top of your normal diet adds calories. Substituting it for other fats is fine for flavor, but do not expect it to shrink your waistline.

Cognitive Health and Alzheimer’s Research

Early-stage research suggests that coconut oil may modestly benefit cognitive function in people with Alzheimer’s disease. A meta-analysis pooling available clinical data found a medium-sized positive effect on cognitive test scores in Alzheimer’s patients who consumed coconut oil compared to controls.²⁵ The proposed mechanism involves the liver converting coconut oil’s medium-chain fatty acids into ketone bodies, which can fuel brain cells that have become less efficient at using glucose. The research is still in its early stages, and no one should treat coconut oil as a substitute for medical care, but it is one of the more interesting areas of ongoing investigation.

Not a Sunscreen

Several viral articles have claimed that coconut oil provides meaningful sun protection. It does not. A rigorous study that measured the actual UV-blocking ability of five commonly promoted plant oils, including coconut oil, found in-vivo SPF values of just 1.2 for coconut oil. The researchers traced the inflated SPF claims in earlier studies to methodological errors.²⁶ An SPF of 1.2 blocks essentially nothing. Use real sunscreen.

Diaper Rash Prevention

Given coconut oil’s moisturizing and mild antimicrobial properties, it seems like a natural candidate for preventing diaper rash in infants. A randomized clinical trial in a neonatal intensive care unit, however, found no benefit. Time-to-rash was similar in both the coconut oil and standard care groups, and adverse events were documented in nearly a third of participants.²⁷ Established diaper creams with zinc oxide remain the better choice for prevention.

Everyday Household and Personal Care Uses

Beyond the uses with clinical research behind them, coconut oil has a long list of practical household applications where its physical properties, solid below about 24°C, liquid when warm, mildly fragrant, and safe to ingest, make it naturally useful:

Makeup remover: A small amount on a cotton pad dissolves even waterproof mascara and leaves skin moisturized, though you should follow with a proper cleanser if your skin is acne-prone.
Shaving lubricant: It provides a smooth glide and leaves skin soft, working on legs, underarms, and faces. It can gum up multi-blade razors over time, so rinsing frequently helps.
Cuticle and nail oil: Massaging a drop into dry cuticles softens the skin and can reduce hangnails.
Lip balm: Applied straight or mixed with beeswax and a few drops of essential oil, it makes a simple, effective lip treatment.
Leather conditioner: A thin coat rubbed into leather bags, shoes, or furniture restores suppleness and adds a light sheen. Test a small hidden area first, as it can darken some leathers.
Wood conditioner: Rubbed into cutting boards and wooden utensils, it penetrates the grain and helps prevent cracking. Unlike mineral oil, it can eventually go rancid, so use it on items you wash regularly.
Stuck zipper fix: A tiny dab of coconut oil along a stuck zipper track lubricates the teeth without staining fabric the way petroleum-based products can.
Seasoning cast iron: It works for maintaining an existing seasoning layer on cast-iron cookware between uses, though oils with higher smoke points are usually preferred for building up a new seasoning from scratch.

Carrier Oil for Essential Oils and Massage

Coconut oil is one of the most popular carrier oils in aromatherapy and massage for practical reasons. Fractionated coconut oil (the liquid form, with long-chain fatty acids removed) stays liquid at room temperature, absorbs at a moderate pace without feeling too greasy, and has almost no scent of its own, making it a neutral base for blending essential oils. The lice research mentioned earlier illustrates the carrier-oil principle in action: essential oils like clove and anise were diluted in coconut oil to deliver their active compounds safely to the skin and scalp. Massage therapists also favor it because it does not stain sheets as badly as heavier oils and rinses out of fabric more easily. For home use, blending a few drops of lavender or eucalyptus oil into fractionated coconut oil gives you a simple massage or bath oil without the price tag of pre-made blends.
