1Quick answerThe short answer, in a few sentences

Only two oils for hair growth have been tested on their own in human trials for pattern hair loss: rosemary oil on the scalp[1] and pumpkin seed oil (capsules in men,[2] scalp use in women[3]). Coconut, castor and argan oil can improve how hair looks, but have no good evidence for regrowth.[4]

Most other popular oils, from black seed to batana, have animal or lab data at best, or no controlled trial at all. This guide goes oil by oil, from the strongest evidence to the weakest, says what each study actually measured, and explains how to use an oil without irritating the scalp. If your hair loss is patterned, spreading or sudden, a doctor should look at it first.

Rosemary oil is an essential oil, so the drops from a bottle like this one are mixed into a carrier oil before they touch the scalp, as the how-to section below explains.

EvidenceHuman trial for hair loss

Rosemary oil for hair growth rests on one randomized trial: 100 people with androgenetic alopeciaGlossaryAndrogenetic alopecia, or pattern baldness, is the pattern hair loss behind most male and female thinning. It is primarily driven by genetic predisposition and sensitivity to androgen hormones.

used rosemary oil or minoxidil 2%GlossaryMinoxidil is an established medication for certain types of hair loss. It is a drug, not a hair oil, and the FDA-approved label says not to use it for sudden or patchy hair loss.
Open in the glossary →
for 6 months, and both groups had more hair at 6 months, with no significant difference between them.[1] One trial against a low-strength drug is a starting point, not proof; a 2024 review still lists only finasteride and minoxidil as FDA-approved treatments for pattern hair loss.[5] Our Rosemary Oil for Hair Loss entry covers how to use it, how long it takes, side effects and what guidelines say.

Pumpkin Seed Oil

EvidenceHuman trials for hair loss

Pumpkin seed oil is the one oil with a placebo-controlled trial for pattern hair loss, and in that trial it was taken by mouth. In a 2014 trial, 76 men with mild to moderate pattern hair loss took 400 mg of pumpkin seed oil a day in capsules, or a placebo, for 24 weeks. Hair counts rose by 40% in the oil group and 10% in the placebo group, and side effects were similar.[2]

Pumpkin seed oil is a very dark oil pressed from pumpkin seeds like those in the photo. In the men's trial it was swallowed in capsules, not rubbed into the scalp, so pouring the kitchen oil on your hair is not the same thing.[2]

A 2023 systematic review in JAMA Dermatology listed pumpkin seed oil among the supplements whose best-quality studies showed potential benefit for hair loss.[6] Side effects in the men's trial were no different from placebo, but anyone on other medicines should ask a doctor before starting a supplement. Collagen is another popular supplement with only early evidence (collagen for hair growth).

Pumpkin Seed Oil for Women

A 2021 trial applied pumpkin seed oil to the scalp of 60 women with female pattern hair loss, against minoxidil 5% foam, for 3 months. Both groups improved on dermoscopy, a magnified scalp exam: fewer fine vellus hairsGlossaryVellus hair is the fine, short, pale hair that covers most of the body. It is under 30 micrometres wide and under 2 millimetres long.
Open in the glossary →
and less variation in hair thickness, and in the oil group more new hairs growing upright.[3] There was no placebo group and the trial was short, so it shows promise, not proof.

Clinical detail: the dermoscopy numbers

Pumpkin seed oil group (n = 30): hair shaft diversity fell from 30.5% to 24.0%, vellus hairs from 22.5 to 15.8, and upright regrowing hairs rose from 0.13 to 0.9 (all P < .001). Minoxidil 5% foam group (n = 30): hair shaft diversity fell from 31.5% to 21.3% (P < .001) and vellus hairs from 24.7 to 19.5 (P = .02).[3]

Synergistic Oil Combinations

EvidenceHuman trial, as a blend, in patchy hair loss

The best-known blend trial is a 1998 study in Archives of Dermatology. 86 people with alopecia areataGlossaryAlopecia areata is an autoimmune condition that can cause round patches of hair loss in the eyebrows, beard or scalp. Hair often regrows within a few months and may look white or grey at first before the natural colour returns.
Open in the glossary →
massaged either thyme, rosemary, lavender and cedarwood oils in a carrier, or the carrier alone, into the scalp every day for 7 months. 44% of the essential oil group improved, against 15% of the carrier group.[7] Because the oils were mixed, the result cannot be credited to any one oil.

Clinical detail: the aromatherapy trial numbers

Randomised, double-blind, 7 months. Improvement on sequential photographs: 19 of 43 patients (44%) with essential oils against 6 of 41 (15%) with carrier oils (jojoba and grapeseed) alone, P = .008. The photographic alopecia scale showed good agreement between blinded observers (kappa = 0.84).[7]

A 2023 systematic review of complementary treatments for alopecia areata still rated essential oil aromatherapy among the options with the best evidence, while noting that methods and outcomes varied between studies.[8]

Tea Tree Oil

EvidenceHuman trial, only mixed with minoxidil

Tea tree oil has been tested for pattern hair loss in people only as part of a mix. In a 2013 pilot trial, 32 men aged 18 to 30 applied a lotion of minoxidil, diclofenac (an anti-inflammatory drug) and tea tree oil, minoxidil alone, or a placebo lotion twice a day for 32 weeks. The three-part lotion gave a higher hair count, hair weight and hair thickness than minoxidil alone or placebo.[9]

Because tea tree oil was combined with two drugs, the trial cannot show what tea tree oil does on its own. A 2024 review of herbal options for pattern hair loss covers tea tree oil among the remedies that still need more research.[5] Tea tree oil is an essential oil, so it goes into a carrier oil before it touches the scalp.

Coconut Oil

EvidenceHair shaft and quality only

Coconut oil protects hair that already exists. A 2003 lab study in the Journal of Cosmetic Science found coconut oil reduced protein loss from hair when used as a pre-wash or post-wash treatment, while sunflower and mineral oil did not.[10] The authors linked this to lauric acid, which is small enough to enter the hair shaft.

The 2022 systematic review agreed that coconut oil helps brittle hair and head lice, with limited evidence on hair growth.[4] So coconut oil for hair growth and thickness is better described as coconut oil for less breakage.

Castor Oil

EvidenceHair quality only, weak evidence

Castor oil for hair growth and thickness is one of the most repeated home remedies, but the evidence does not support it. A 2022 systematic review of 22 studies found weak evidence that castor oil improves hair shine and no strong evidence that it grows hair or treats baldness.[4]

Castor oil is pressed from the mottled seeds that form inside these spiky capsules. The oil made from them is what the review above looked at, and it showed weak evidence for shine, not for hair growth.

Castor oil is very thick. A case report in the International Journal of Trichology describes a 20-year-old woman whose long hair matted into a hard mass the first time she used castor oil, together with coconut oil, before a hair wash; the tangle could not be undone and the hair had to be cut.[11] For men and women alike, use a small amount, mix it with a lighter oil and comb it through gently.

Argan Oil

EvidenceNo clear benefit found

Argan oil is popular in serums and leave-in products. The same 2022 review found no significant evidence that argan oil improves hair growth, hair quality or scalp infestation.[4] It may still make dry ends feel smoother.

When to Use Argan Oil for Hair Growth?

If you use argan oil, use it on the lengths after washing, for shine and softness. Do not rely on it as an argan oil hair loss treatment; it has not been shown to work as one.

Peppermint Oil

EvidenceAnimal studies only

Peppermint oil has the most striking hair growth result of any essential oil, but it comes from mice. In a 2014 study, mice treated with 3% peppermint oil on the skin for 4 weeks showed the strongest hair growth of four groups, ahead of saline, jojoba oil and 3% minoxidil, with more and deeper follicles and higher levels of IGF-1, a growth marker.[12]

We found no human trial of peppermint oil on its own for hair growth. If you use it, mix a few drops into a carrier oil first, and stop if the scalp stings or turns red.

Lavender Oil

EvidenceAnimal studies only

Lavender oil has a similar result in mice. In a 2016 study, female mice given 3% or 5% lavender oil on the skin, 5 days a week for 4 weeks, had more hair follicles, deeper follicles and a thicker skin layer than mice given saline.[13]

Lavender was also one of the four essential oils in the alopecia areata blend trial described above, so its share of that result is unknown.[7] We found no human trial of lavender oil on its own for hair growth.

Frankincense Oil

EvidenceLab study only, on microbes

Frankincense oil comes from Boswellia resin. In a 2016 lab study, Boswellia serrata essential oil slowed the growth of several skin and scalp microbes, including Malassezia yeast, in test plates.[14] That is a lab finding about microbes, not about hair growth.

We found no human trial of frankincense oil for hair growth. Claims about frankincense benefits for hair, or frankincense oil on the scalp for thicker hair, go further than the data.

Jojoba Oil

EvidenceNo hair growth trial; used as a carrier

Jojoba is chemically not an oil at all. A 2021 review in Polymers describes it as about 98% wax esters, which is why it feels light and spreads easily. It is used in conditioners and hair oils for that texture, and folk medicine has long claimed it promotes hair growth.[15]

For jojoba oil and alopecia, the only clinical use we found is as a carrier. In the aromatherapy trial for alopecia areata described above, jojoba was part of the carrier mix given to both groups, and the essential oils, not the carrier, made the difference.[7] In two mouse studies, jojoba served as the plain control.[12][13]

Black Seed Oil

EvidenceNo controlled trial found

Black seed oil comes from Nigella sativa, a plant with a long history in folk medicine. We searched the indexed medical literature and found no controlled trial of black seed oil on its own for hair loss. Claims online usually borrow from lab studies on the seed's other uses.

No trial does not mean it harms hair; it means nobody has shown that it helps. It can, however, cause a skin allergy: a 2020 case report identified thymoquinone, a compound in black seed oil, as the cause of allergic contact dermatitis to the oil.[16] Patch test it before using it on the scalp.

Sesame (Til) Oil

EvidenceNo controlled trial found

Sesame oil and til oil are the same product; "til" is the Hindi name for sesame. It is widely used for head massage in South Asia. We found no controlled human trial of sesame oil for hair growth, so its benefits for hair rest on tradition and on what any oil does to the hair surface.

Til Oil for Hair Benefits

As a pre-wash oil, til oil can reduce friction while you comb and leave the lengths softer. Those are cosmetic effects on hair that has already grown. They do not change how many follicles are active.

Sesame Oil for Hair Benefits

Sesame oil is a vegetable oil rich in fatty acids, so it coats the hair shaft like other plant oils. The honest summary is the same as for til oil: pleasant to use, low cost, and no trial showing more growth.

Oil as a Hair Growth Treatment

An oil for hair loss treatment makes sense only when you know the cause of the loss. Pattern hair loss is driven by DHT, a hormone, and our guide to DHT and hair loss explains why oils rarely change it. Stress, iron deficiency and thyroid problems can also push hairs into shedding, and each needs its own treatment.[17]

Sudden hair loss, round bald patches, or shedding with a sore, scaly or inflamed scalp should be checked by a dermatologist before you try any oil. These can be signs of conditions that need medical treatment, and an oil can delay the diagnosis.

Olive oil and almond oil appear in many lists of the best oil for hair loss treatment, but we found no controlled trial for either.

Natural Oils for Hair Growth at Home

Hair oil home remedies are cheap and mostly safe, which is why they are popular for women and men alike. The best oil for hair growth at home is the one that matches the problem:

  • Thinning at the crown or temples: rosemary oil on the scalp, given at least 6 months.
  • Dry, breaking lengths: coconut oil before washing.
  • Frizz and shine: a few drops of argan or jojoba oil after washing.
  • Patchy hair loss: see a dermatologist before using anything at home.

Olive oil home remedies for hair growth are popular, but olive oil slowed skin barrier repair in a mouse study[18], so a patch test is worth doing first.

How to Use Oils for Hair Growth?

How you use an oil matters as much as which one you choose. Essential oils such as rosemary or peppermint are concentrated and must go into a carrier oil before they touch skin. Base oils such as coconut, mustard or batana oil can go on directly, but less is more.

  • Test a small amount on the inner arm first.
  • Part the hair and apply the oil to the scalp with your fingertips.
  • Massage gently for a few minutes, then leave it on for a short time.
  • Wash it out with a mild shampoo so it does not build up on the scalp.
Four steps before using a new hair oil: patch test, dilute essential oils, use a small amount on the scalp, and stop if the skin reacts

Does Oil for Hair Growth Work?

For most oils, the answer is no, or not yet shown. The claimed oil for hair growth benefits, including onion oil, lauki oil and batana oil benefits, come from tradition and marketing; we found no controlled trials of these oils. The single-oil human trials for pattern loss, one with rosemary and two with pumpkin seed oil, are small and have not been repeated at scale.[1][2][3] Oregano oil has no human trial either (oregano oil for hair growth).

What Essential Oil Volatiles Do at the Follicle?

Essential oils are mixes of small, volatile compounds. The peppermint and lavender results above show that these compounds can act on follicles in mouse skin.[12][13] Mouse skin cycles differently from the human scalp, so these results show a mechanism worth testing, not a treatment.

Hair Growth Oil Side Effects

Any oil can irritate a sensitive scalp, and a red, itchy scalp can shed more. Watch for these signs and stop if you see them:

  • Redness, burning or itching that lasts after washing.
  • Bumps, scaling or weeping skin.
  • More shedding than usual in the weeks after starting.
  • Tangling or matting with thick oils such as castor.

Minoxidil is a drug, not a hair oil. The FDA-approved product label warns users to stop and ask a doctor about chest pain, a fast heartbeat, dizziness, sudden weight gain or swollen hands and feet, and not to use it for sudden or patchy hair loss.[20] Fish oil is an oral supplement, so discuss it with a doctor. For palm, batana, nao and sesa oil, we found no published safety data for scalp use.

Frequently Asked Questions

What Oils Make Your Hair Grow Faster?
No oil has been shown to make hair grow faster than its natural rate. Rosemary oil matched minoxidil 2% in hair count after 6 months in one trial, and pumpkin seed oil capsules beat placebo in another.[1][2] Both changed hair count, not growth speed.
Does Batana Oil for Hair Growth Work?
We found no published controlled trial of batana oil for hair growth. It may soften hair like other plant oils. Claims that it regrows hair are not backed by clinical data, so treat it as a cosmetic oil and patch test it first.
Can Olive Oil Help for Hair Growth?
There is no trial showing that olive oil grows hair. It can coat and soften the lengths. In a mouse study on skin, olive oil slowed barrier repair,[18] so people with a sensitive or flaky scalp should test it on a small area first.
Is Almond Oil Good for Hair Growth?
Almond oil is a light conditioning oil, but we found no clinical trial of almond oil for hair growth. Use it for softness and shine if you like it. Anyone with a nut allergy should avoid it.
When to Use Rosemary Oil for Hair Growth?
The trial participants used rosemary oil on the scalp over 6 months, and no change showed at 3 months. If you try it, use it consistently and judge it at 6 months. Stop if your scalp becomes irritated.
When to Apply Castor Oil for Hair Growth?
Castor oil has no good evidence for growth. If you use it for shine, apply a small amount mixed with a lighter oil before washing, and comb it through. Avoid using large amounts on long hair because of the risk of matting.
When to Use Batana Oil for Hair Growth?
Without trial data, there is no proven best time. Most people use batana oil as a pre-wash treatment and wash it out. If your hair loss is getting worse, see a doctor instead of waiting for an oil to work.
Does Scalp Massage Help Hair Growth?
The evidence is thin. In a small 2016 study, 9 healthy men used a massage device for 4 minutes a day for 24 weeks. Their hairs became slightly thicker, from 0.085 to 0.092 mm, but hair density and growth rate did not improve compared with an untreated area.[21] Massaging an oil into the scalp is fine if you enjoy it, but it is not a hair loss treatment.
Can Hair Oil Cause Acne on the Forehead?
Yes. The American Academy of Dermatology explains that oil in hair care products can reach the skin and clog pores, causing tiny bumps along the hairline, the forehead or the back of the neck. This is called acne cosmetica. After you stop using the product, it can take 4 to 6 weeks to clear.[22] If your skin has not cleared by then, see a dermatologist.

When an Oil Is Not Enough

If you have been losing hair for more than a few months, or you can see your scalp through thinning areas, it is worth finding the cause. Our guide to why hair falls out covers the common reasons, and the Norwood scale shows how male pattern loss progresses. Women can read about hair transplant for women and who is a candidate.

Checked, but not used as evidence

A 2025 trial compared rosemary oil blends (with lavender, and with castor oil) against coconut oil. It was funded by the maker of the products, its 90 participants were described as healthy adults, and a correction to it was published in 2026. We list it so you can read it yourself, but this entry does not rely on it.[23]
