Along with coconut oil and castor oil, argan oil was one of the first hair oils I discovered when I started expanding my haircare routine beyond basic shampoos and conditioners. And when I tried my first argan oil-infused product, I instantly fell in love with its smooth feel, powdery scent, and the way it made my curls feel lightweight and bouncy. What I didn't yet realize was that argan oil was protecting my hair from everyday damage—like heat and pollution—nor did I know that argan oil products vary in type, potency, and quality.
In my mission to unpack all things argan oil for hair, I consulted experts, including two board-certified dermatologists along with a celebrity hairstylists, in order to better understand what argan oil is, how it works, and how to find the best argan oil-infused products for every type of hair.
What Is Argan Oil?
So, where does argan oil come from? Board-certified dermatologist Dr. Marisa Garshick says, "It is derived from the fruit of Argania Spinosa, a tree native to Morocco and traditionally used to improve the appearance of skin"—yes, you can use argan oil on your skin, too—"and hair, as well as can be used in wound healing."
Indeed, Dr. Rebecca Marcus, board-certified dermatologist and founder of Maei MD, points out that scientific studies indicate that argan oil "has a regulatory effect on sebum secretion, and it has been shown to increase hair elasticity when applied topically." This, she explains, is because "it consists of mostly unsaturated fatty acids and is rich in oleic and linoleic acids, as well as antioxidants including Vitamin E, all of which contribute to organ oil’s ability to support hair’s elasticity and protect it from damage that may lead to breakage."
Because of these health-boosting effects, Dr. Marcus says that argan oil enhances hair shine by boosting it from within.
Why Use Argan Oil on Your Hair?
Why use argan oil? Dr. Garshick explains, "Argan oil helps to moisturize, as it is rich in fatty acids to help strengthen the skin barrier and also contains squalane to help hydrate and protect. It can also help to reduce inflammation as it contains linoleic acid which is thought to be anti-inflammatory. In this way, it is also known to help promote shinier and smoother hair."
Plus, using argan oil can help your other moisturizing products penetrate your hair follicles more effectively. "Argan oil contains oleic acid and linoleic acid, which are thought to be penetration enhancers, and help improve penetration of other ingredients into the hair and can also reduce inflammation," she says. "Linoleic acid can help with dryness as it has moisturizing benefits and support the skin barrier. Additionally, argan oil contains antioxidants such as polyphenols and Vitamin E to help with free radical damage, making the oil helpful in addressing overall hair health."
In short, Dr. Garshick recommends argan oil for those who are "experiencing dryness or dullness of their hair." Celebrity hair stylist Dominick Pucciarello agrees, saying that argan oil is "better for enhancing manageability than other oils are."
What to Look For in Argan Oil Products
Dr. Garshick says that when it comes to finding the ideal argan oil products, "generally the full-strength version is best for those with thick or curly hair." In other words, you should consider opting for a pure, organic argan oil treatment.
However, she concedes that argan oil also "works well as a conditioner to help nourish the hair and leave the hair softer and smoother. It can also be found in heat protection products to help protect the hairs, hair masks, serums, and styling products."
And what should you avoid in an argan oil product? Pucciarello says it's best to avoid "sulfates, mineral oil, parabens, denatured alcohols, synthetic fragrances, formaldehyde, and silicones."
Dr. Marcus does point out that silicones "tend to be best for protecting hair before heat styling for adding shine and taming frizz," and various studies continue to indicate that silicones can be effective short-term solutions for frizz, breakage, and dryness. However, other studies point out that that silicones remain unsustainable from an environmental perspective in addition to causing dryness after consistent use over an extended period of time.
Possible Side Effects
While argan oil may seem like a magical hair panacea, Pucciarello says, "Using argan oil over time will actually dry your hair oil. The oil starts to create a barrier, breaking out any moisturize trying to get in." So be sure to mix up your hydration routine with other potent options, such as coconut oil, castor oil, and high-quality leave-in conditioners. And if you're concerned that too much product build-up is blocking moisture from penetrating your strands, consider a clarifying shampoo for a deep cleansing.
Best Argan Oil Shampoos
Pucciarello says that argan oil—and products infused with it—can "reduce breakage and split ends and keep your scalp healthy." Thus, it's worth integrating into your shampoo routine. That way, your wash routine will be infused with an extra boost of hydration and scalp support.
"Containing a blend of organ oil, rosehip oil, and coconut oil, this nourishing shampoo helps to soften and smooth the hair, while also reducing frizz and protecting the hair," Dr. Garshick attests. "It is especially good for those with frizzy, dry or damaged hair but can be used in color-treated, keratin-treated, chemically-treated and relaxed hair."

Best Argan Oil Leave-In Treatments
In the words of Pucciarello, argan oil "can moisturize the hair and scalp and protect hair from everyday damage." Thus, you'll probably want to make it part of your daily styling routine. Below, some of the best argan oil leave-in treatments that will guard your hair against pollution and other irritants while you go about your day.
"Designed to help improve moisture from head-to-toe, this multitasking oil contains fatty acids and vitamins," Dr. Garshick tells us. "It can be used on the hair to tame frizz and flyaways, but absorbs quickly. It can also be used to boost moisture on the skin involving the face and body and may help improve the appearance of fine lines and wrinkles."
Pros: organic; free of silicones, sulfates, and parabens; affordable
Cons: thick, so those with very thin hair may find it greasy
Customer Review: "I bleached and dyed my hair up to 6 times in 6 months and my hair was paying for it. This oil seriously has saved my hair! I already had fry and brittle hair prior to dying it. I put it on at night and put it in a braid. I have also experienced less breakage and soft ends!" -ULTA
Dr. Garshick stands behind this treatment, which can regularly be massaged into the scalp before styling. "Using PhytoCellTech Argan Stem Cells, this product helps to prevent hair breakage," she explains, "while argan oil nourishes and conditions to leave the hair looking softer, smoother, and shinier."

Cons: small bottle
