How can olive oil benefit the hair?

Brendan Camp, MD, FAAD, is a double board–certified dermatologist at MDCS Dermatology. He says olive oil is so good for the hair and scalp (more on that in a minute) because it mimics the natural sebum that's produced by our skin. "Olive oil has gained popularity as the interest in using natural or organic skincare products has increased," he says. "Olive oil is used on the hair as a substitute for your body's own natural oil—sebum. Sebum is produced by oil glands in the skin, which drain directly into hair follicles. It functions to coat the hair shaft with oil, which keeps the hair soft, smooth, and pliable. Without sebum, the hair shaft would become dry, coarse, and brittle." In other words, olive oil moisturizes the hair and scalp, boosts smoothness, and prevents breakage and damage.

Jennifer Korab is a celebrity hairstylist. She says olive oil benefits the hair thanks to its rich vitamin, antioxidant, and fat content. "Olive oil can benefit hair because it is packed with vitamins A and E, antioxidants, and healthy fats that deeply nourish and enhance shine and hydration," she says. "It also softens the hair, tames frizz, and smooths split ends. Its moisturizing qualities make it ideal for dry or damaged hair while also helping to soothe the scalp and minimize dandruff."

How can olive oil benefit the scalp?

No surprise here—olive oil is just as beneficial to the scalp as it is to the hair. Take it from Korab. She says, "Olive oil helps nourish the scalp by moisturizing and soothing dryness, reducing flakes, and improving overall scalp health. Its anti-inflammatory properties also help calm irritation and combat dandruff, keeping the scalp balanced and hydrated."

Celebrity hairstylist Michelle Cleveland of Hair Addict Salon agrees, adding that it's even been shown to boost circulation. When applied to the scalp, it brings more blood flow to the hair follicles, which can strengthen them and spur better hair growth.

What hair type is it best for?

The experts say anyone can use olive oil. However, it's best suited for thicker, denser hair types. "Since olive oil is as pure and natural as it comes, it wouldn't ever hurt anyone to use it," Cleveland says. "However, for someone with fine hair, it can cause the hair to feel flat and appear greasy if used too much and/or not clarifying well enough post-treatment."

Korab adds, "Olive oil is ideal for thick, coarse, or curly hair, as it delivers deep moisture and tames frizz effectively. It's also a great option for treating dry or irritated scalps, particularly in cases of dandruff, due to its soothing properties. It's less suited for fine or oily hair types, as its weight can cause buildup and leave the hair feeling greasy."

The only time you should avoid using olive oil is if you have a scalp condition. "If someone is suffering from a medical scalp condition, such as fungus patches or dandruff, I would consult a doctor first," Cleveland says. "These types of conditions require the follicles on the scalp to remain unclogged and free of buildup." Since olive oil is, well, an oil, it could clog up the follicles too much and exacerbate the symptoms.

Are there any downsides to using olive oil on the hair and scalp?

The only downside to using olive oil on your scalp and hair is the thick, oily texture, which is why the experts often recommend using hair products that have been formulated with olive oil rather than the real thing, especially when it comes to fine and oily hair types. "You can apply pure olive oil directly to your scalp for its moisturizing and nourishing benefits," Korab says. "However, when included in haircare products, olive oil is often paired with other ingredients that enhance its effects and improve absorption. Products formulated with it may offer a more balanced approach to addressing specific scalp and hair needs." Since olive oil can be heavy and hard to wash out, Korab warns that it may lead to buildup. Even worse, if you overuse it, you could be running the risk of clogged pores and greasiness. That's why she recommends using it sparingly.

Cleveland agrees. "While you can simply apply olive oil directly to the hair and scalp, it can be quite thick and heavy, so I would advise looking for a product that contains it," she says. She recommends looking for a product that doesn't contain a lot of additives or artificial ingredients and using a clarifying shampoo after treatment to properly remove the oil.

Camp says olive oil could cause breakouts due to its occlusive nature. "Everything in moderation; too much oil on the skin can potentially occlude or block pores and contribute to acne," he says.

How to Use Olive Oil on the Hair and Scalp

You can apply pure olive oil to your strands to reap all the benefits. Be sure to use a light hand so you don't coat the strands and cause buildup and/or complicate removal. "You can apply pure olive oil directly to your scalp for its moisturizing and nourishing benefits," Korab says. "However, when included in haircare products, olive oil is often paired with other ingredients that enhance its effects and improve absorption. Products formulated with it may offer a more balanced approach to addressing specific scalp and hair needs."

Before you reach for any old olive oil, consider Camp's recommendations: "If using pure olive oil, look for unrefined, cold-pressed oil, which produces the purest form of the product. Refinement or using heat to extract the oils can introduce chemicals, preservatives, or contaminants to the production process."
