  • MAIN BENEFITS: Increases hair thickness and growth rate, aids in the healing of split ends and damaged hair, heals dandruff and scalp psoriasis, and replaces hair shaft oil.

  • WORKS WELL WITH: Peanut oil is a good match for humectants, which offer moisture to the scalp skin and hair shaft in a different way than oils.
  • DON’T USE WITH: Cleansing surfactants in shampoo or other hair care products remove oil, grime, and residue from the hair’s surface, which might interfere with the action of an oil treatment.

The Advantages of Peanut Oil for Hair

While peanut oil might not be your first idea when it comes to hair treatments, it should be—especially if you have dry hair.

“Peanut oil has many amazing advantages, such as boosting hair thickness, minimizing protein loss in hair, and treating damaged hair and split ends,” explains Hu. “Because it is high in antioxidants, it can help heal dandruff and even scalp psoriasis.”

Treats dandruff and scalp psoriasis: According to Hu, peanut oil contains antioxidants that are extremely hydrating and frequently assist with dry scalp diseases like dandruff. Peanut oil also includes vitamin E, which has been shown in trials to help avoid an imbalance between oxidative stress and antioxidant defense in people with psoriasis.

Restores hair oils: Peanut oil can be used to replace oil on the hair shaft. According to Camp, “normally, sebaceous glands in our scalp skin produce oil (sebum) into the hair follicle, which coats the hair shaft.”

“Sebum acts to soften, smoothen, and pliable the hair shaft.” Helps de-frizz hair: According to Camp, frizzy hair is caused by a lack of moisture in the hair shaft. He claims that treating it with peanut oil traps in moisture and makes the hair more manageable.

“Peanut oil includes numerous fats—such as vitamin E, which helps minimize protein loss in hair—that contribute to thicker, more moisturized, and healthier hair,” Hu says.

Repairs damage: According to Hu, “peanut oil is hydrating and acts to help heal split ends as well as regenerate and revive damaged hair.”

Peanut oil might assist with curl definition if you want greater definition in your curls. “Peanut oil can help restore curl structure,” Camp says.

Considerations for Hair Type

Those with dry scalps and hair will benefit the most from an oil therapy. “Dry hair or scalp skin is best suited to an oil treatment since peanut oil functions as an occlusive to seal in moisture and as an emollient to smooth dry, damaged hair,” says Camp.

“People with overly oily hair or scalp skin may not require the added advantage of peanut oil treatments since their bodies produce enough sebum.” According to studies, peanut oil can aid with skin barrier repair due to its moisturizing properties on human skin (without increasing transepidermal water loss), which is why professionals frequently prescribe it for people with scalp issues. “It’s an effective and natural solution for people suffering from dandruff or scalp psoriasis,” Hu says.

People with damaged hair, in addition to those with dry scalps, might try using peanut oil. “Peanut oil is an excellent restorative factor for persons with damaged hair,” says Hu. “It works best for individuals with dry hair since it deeply moisturizes and nourishes it.”

Those with oily hair, on the other hand, should try it first since “it may enhance oil production owing to its hydrating features,” according to Hu. “However, it has a slew of excellent benefits, so there’s no harm in giving it a shot.”

Camp adds that folks with oily hair should avoid it if they aren’t seeing results since “their body already produces significant quantities of sebum.” “Peanut oil is not a very comedogenic oil,” he continues, “but patients prone to scalp acne may wish to utilize peanut oil treatments with caution lest they suffer a breakout from plugged pores.”

How to Apply Peanut Oil to Your Hair

While there aren’t many hair products on the market that include peanut oil, both experts advocate putting it on your hair. Hu recommends using peanut oil once or twice a week for best effects, since using it too frequently will cause the oil to deplete important oils from your hair.

She also mentions that, depending on how you use peanut oil for hair, it may be used at any time of day, on wet or dry hair. Camp concurs, but adds that “Exposure of hair oil to the skin of the face, neck, or back may cause excess oil to accumulate on the skin and lead to blocked pores.

Excess hair oil can also discolor garments or linens.” So, how do professionals propose using peanut oil in your hair? “Cold-pressed peanut oil works miracles, and if it’s organic, it doesn’t contain any dangerous pollutants or chemicals,” explains Hu. “Peanut oil can be used to promote hair development.

Combine two tablespoons of peanut oil, one egg yolk, and ground peanuts in a mixing bowl. Apply the hair mask to your scalp and gently massage it in for two hours. Continue with your normal washing regimen once it has sat.”

“Peanut oil is highly hydrating and is effective as a therapy for dandruff and scalp psoriasis,” says Hu of a dandruff mask. “To fight dandruff, use peanut oil, tea tree essential oil, and lemon juice. Allow it to sit for no more than two hours after kneading it into your hair and scalp. Then proceed with your usual washing regimen.”

“Warm a few teaspoons of the oil and apply it carefully (without burning yourself) to divided scalp skin as a scalp therapy to address flaky skin,” explains Camp. “Before rinsing, leave it in place for a few minutes or cover with a shower cap for added hydration.

While the scalp is being treated, gently run some of the remaining oil into the hair to handle any frizz or difficult-to-manage areas. If there appears to be too much oil in the hair, use a moderate wash to clean the hair and scalp.”


Is peanut oil good for your skin?

Yes. Topical peanut oil protects the skin from UV radiation and has been demonstrated to hydrate the skin.

Can those who are allergic to peanuts use peanut oil?

According to research, refined peanut oil-containing formulations are safe for topical application, even in people who are allergic to peanuts. Before using peanut oil on your skin, always perform a patch test, especially if you have a peanut allergy.

Is there any retail hair product that contains peanut oil?

Camp observes that there are few hair products with peanut oil on the market. Look for the ingredient Arachis hypogaea (Peanut) Oil while shopping for a product.
