Squalane oil is a popular ingredient amongst skincare enthusiasts, loved for its hydrating and moisturizing properties. Often confused with squalene oil, squalane is the hydrogenated derivative of squalene. Squalane has a longer shelf life than squalene, and therefore is typically the ingredient found in your favorite products.

Beyond its benefits for the skin, it turns out squalane oil also makes for a great addition to your haircare routine. “Squalane oil is a great ingredient for haircare because it replenishes moisture to your strands and protects the hair from further damage,” says StyleSeat hairstylist Erinn Courtney.

We asked Courtney and board-certified dermatologist Snehal Amin, MD, FACMS, FAAD, to share the benefits of squalane oil for hair.

So what all can this emollient do for hair? Keep reading to find out.

SQUALANE OIL FOR HAIR

TYPE OF INGREDIENT: Hydrator, emollient

MAIN BENEFITS: Adds moisture to the hair, prevents hair breakage, and helps prevent frizz

WHO SHOULD USE IT: In general, anyone can use squalane oil for hair. Those with dry, damaged hair will often see the most benefits.

HOW OFTEN CAN YOU USE IT: Squalane oil is generally safe to use as needed, as often as daily application.

WORKS WELL WITH: Generally, squalane oil works well with all ingredients.

DON’T USE WITH: There are no known ingredients that are unsafe to use with squalane oil.

Benefits of Squalane for Hair

  • Moisturizes hair: Courtney notes that squalane oil is great for haircare because as a hydrator, it replenishes moisture to hair strands.
  • Increases shine: Thanks to the moisturizing properties noted above, squalane oil can create a natural shine that you often see in healthy hair. “For most hair, it will also add a silky, smooth texture,” adds Courtney.
  • Prevents breakage: “Squalane prevents moisture loss and breakage of the hair,” says Amin.
  • Tames frizz: Breakage can lead to frizz—as many of us know all too well—often due to hot tools, weather, and other factors that contribute to dry, fragile strands. “Squalane prevents moisture loss and breakage which means it will tame frizzy hair,” Amin says.
  • No greasy finish: All too often, what seems to be the perfect hair oil ends leaving a greasy residue on hair, leading to the opposite of a fresh, clean look. The experts both note that what makes squalane oil special is the lack of greasy trail it leaves behind (though a little does go a long way).

Hair Type Considerations

One of the many benefits of using squalane oil for hair is that it does not discriminate. “Squalane oil works great for all hair types,” shares Courtney. “You can apply more or less of the oil depending on your texture and density. If you are someone who applies a lot of direct heat on your hair or just notices that your hair is feeling extra dry, squalane oil will be a great way to replenish some moisture back into your hair follicles.

That being said, given its hydrating and moisturizing properties, dry hair will generally soak in the benefits (literally). “People with drier complexions or hair are more likely to notice the benefits of regular use,” Amin shares. “Because it is stable at high temperatures it also protects the hair from heat. Think softer, shinier, and smoother hair.”

Generally, if you are experiencing a dry, itchy scalp or dandruff, applying squalane oil directly to your scalp will help alleviate some of the dryness. “For this reason,” adds Amin, “it is also helpful for eczema, psoriasis, and dermatitis.”

It’s worth noting that people who have naturally straight or fine hair will want to be more frugal with their use of squalane oil. “This ingredient may weigh your hair down even more so I would recommend avoiding the scalp and roots whenever applying it,” Courtney says. And like any new ingredient, it’s important to test the product on a small area of the scalp first to check for any potential allergies. Signs of an allergic reaction include swelling, redness, and itching, Amin notes.

How To Use Squalane Oil For Hair

Squalane oil is a generally easy product to use for the hair because it does not require any DIY formulating. “Squalane oil can be applied directly to your hair,” says Courtney. “You can apply a few drops of the oil directly onto your scalp and give yourself a nice scalp massage to work the product throughout the rest of your hair. It can also be applied directly to the mid-shaft and ends of your hair—whatever works best for you. I would also recommend using squalane oil in any hair treatments, deep conditioners, or steam treatments which will all help the ingredient to better penetrate the hair follicles and provide deeper hydration.” Amin concurs.

The experts agree that squalane oil is a great, typically safe-for-all option for helping keep locks luscious and hydrated while skipping any unwanted grease or residue. Whether it’s applied directly to hair or added in your favorite products, this heavily beneficial emollient gets the seal of approval from both dermatologists and hair experts alike.
