Yes, you read that right: Your go-to culinary ingredient may have a home not only in your kitchen cabinet, but also in your beauty closet. Along with other hair oils, like castor oil, coconut oil, and argan oil, olive oil has been lauded by people everywhere for its purported abilities to soften and grow hair. But is there any truth to this, or is it simply another fleeting beauty trend?
Celebrity hair stylist Dominick Pucciarello sets the records straight: "Olive oil reduces damage and breakage and increases moisture, shine, softness, and hair growth," he says, adding that it can also strengthen the hair shaft, fight split ends, and decrease dandruff. Some skincare products also contain olive oil.
But before you start seasoning your hair the way you season your salad, read on for dermatologist- and stylist-approved advice on all things olive oil haircare.
The Benefits of Olive Oil for Hair
On the science of olive oil haircare, board-certified dermatologist and founder of Maei MD Dr. Rebecca Marcus writes, "Olive oil is composed of mostly oleic acid, but also contains arachin, linolein, and palmatin. Virgin olive oil is rich in antioxidants as well." In terms of moisture, this means that the oil "works as an emollient by sealing the hair cuticle and allowing it to retain moisture."
Plus, olive oil can help defend your hair from environmental hazards. "Its antioxidant properties account for its ability to protect hair from UVB and UVA-induced cell damage," Dr. Marcus says. "Olive oil has been shown to have anti-fungal properties, which may be a result of it functioning as a mechanical barrier between the scalp/hair and the environment."
Drawbacks of Olive Oil for Hair
Pucciarello, Dr. Marcus, and board-certified dermatologist Dr. Marisa Garshick all agree that olive oil may not be best for those with thin or straight hair, because it may weigh strands down and make hair look and feel greasy. Dr. Marcus also says, "If one has oily hair already, olive oil should not be applied to the hair."
Dr. Garshick adds that if you have thin hair and remain intent on trying olive oil haircare, "it is best to apply to the ends to avoid weighing the hair down."

Secondly, Dr. Garshick warns, "Olive oil can potentially encourage the growth of yeast that lives on the scalp, so it is best to avoid applying directly to the scalp, especially if you're dealing with seborrheic dermatitis."
Pucciarello also advises against applying olive oil directly to the scalp, adding that the overgrowth of yeast may also cause one to break into a skin rash or develop blackheads and acne.
Finally, on the topic of acne, Dr. Garshick says that those already suffering from acne of the face or back may also want to steer clear of using olive oil in their hair.
"If you are acne-prone, it is best to avoid a leave-in product which can contribute to worsening breakouts if the oil comes into contact with the skin on the forehead or back," she says. "This can contribute to clogged pores and breakouts."
Who Should Use Olive Oil for Hair?
These potential drawbacks beg the question: Who is suited to use olive oil in their hair?
"I use olive oil for thick, curly hair," answers Pucciarello, "especially if your hair is dry and coarse. This is great for processed hair (like hair that has been treated with relaxers, perms or bleach) and also split ends as it can help to smooth broken or burned ends."
Dr. Garshick also says that olive oil is great for those who feel that their hair "looks dry or dull, as olive oil can help to nourish the hair."
Olive oil may be of particular use for those whose hair has suffered as a result of their environment. Dr. Marcus explains, "Olive oil could be beneficial to those with dry hair that is frequently exposed to environmental toxins and especially UV radiation. So, for example, for those who spend a lot of time outdoors in the sun, and for swimmers."
Finally, Dr. Marcus says, "Olive oil combines well with honey and beeswax, and has even been shown to improve the redness, scaling, and itching of the scalp frequently encountered in psoriasis when applied in this combination."
Still, if you are thinking of trying olive oil as a hair or scalp treatment, check with your dermatologist or trichologist first—particularly if you have a condition like psoriasis.
What to Look For—and Avoid
While it's tempting to opt for cheaper products, Dr. Marcus advises against skimping on quality when it comes to your hair products—especially when they contain olive oil.
"Look for a high-quality product from a reputable brand," she says. "Oils have a tendency to turn rancid, so the formulation must be solid. Products made by reputable, trusted brands will have gone through stability testing to ensure that their products will not spoil faster than expected."

Best Pure Olive Oils For Hair
While there are a number of fabulous olive oil-infused products on the market, Puccariello recommends going straight to the source and using pure olive oil by itself.
Nervous about how to apply it? Dr. Marcus says, "A small amount of extra virgin olive oil can be used directly on the hair and does not need to be incorporated into a product." Remember: Less is more!
"Choose virgin or extra virgin to benefit from olive oil’s potent antioxidants," Dr. Marcus advises. In addition, Dr. Garshick says to "look for extra virgin organic olive oil as it is the least processed and contains more hair helping nutrients." This extra virgin olive checks all the boxes—and it's affordable, too.
