When I decided to go natural a few years ago, I knew that one of the biggest challenges of my hair journey would be finding the right products. The one thing I knew to turn to was natural oils. Why? Well, many nourishing hair oils such as peppermint oil, olive oil, and tea tree oil are the subject of rave reviews by experts in the haircare space. After much exploration, the one oil that kept my hair strong and healthy was canola oil. Although it came to prominence as a cooking oil, canola oil has many well-documented health and beauty benefits.1 But what is it and what does it do for our hair? Keep reading to learn all about canola oil for hair, complete with insights from haircare experts as well as a few product recommendations.

What Is Canola Oil?

True to its name, canola oil is extracted from the canola seed, a variety of rapeseed that’s low in erucic acid. It’s grown primarily in the prairie regions of western Canada. Although it remains one of the most versatile and popular cooking oils to grace many pantries, it also has numerous beauty and wellness benefits and can be applied to hair, skin, and nails to moisturize and strengthen.2

Canola oil contains vitamin E, an active ingredient that has been hailed as a trusted solution for many haircare woes.3 Although canola oil boasts many hair-transforming properties, it shouldn’t be used in cases of serious hair loss. In cases like this, it’s always best to seek advice from a medical professional. In spite of this, canola oil can revive dull hair, repair hair follicles, and improve blood circulation to the scalp.

To find out what makes canola oil so beneficial to hair, we’ve sought some knowledge and expertise from trichologists Shab Reslan and Gretchen Friese, as well as medical advisor Dr. Angela Phipps and skincare expert Dr. Catharine Denning. Ahead, they share everything there is to know about canola oil and the things it can do for your hair—you can thank us later.

TYPE OF INGREDIENT: Moisturizer and hydrator

MAIN BENEFITS: Keeps scalp and hair healthy, promotes hair growth, prevents dryness

WHO SHOULD USE IT: In general, canola oil can be used on all hair types due to its lightweight texture.

HOW OFTEN TO USE IT: One to two times a week

WORKS WELL WITH: Other moisturising oils like coconut oil, olive oil, and avocado oil.

DON’T USE WITH: No known contradictions—however, be aware that canola oil is a vegetable oil, so discuss with your doctor before use if you have any allergies.

Benefits of Canola Oil for Hair

Don’t let canola oil’s widespread availability and prevalence in the kitchen fool you: This unassuming ingredient may be one of the best ways to improve your hair health. This oil has an impressive amount of benefits, and moisturizing your hair with it can lead to improvement all around.

Promotes hair growth: ‘’Canola oil greatly benefits the hair and scalp, thanks to its fatty acid content,’’ Reslan says. ‘’It contains a high percentage of oleic acid—60%—and 20% linoleic acid. Linoleic acid is lightweight in texture and is great for moisturizing the scalp and stimulating hair growth.’’

Moisturizes and softens the hair: Hair needs a balance of moisture and protein to flourish. Moisture helps retain hair’s elasticity. Without it, hair can become dry, brittle, and at risk of breakage. When detangling, styling, or performing any other type of manipulation, soft, supple, and moisturized hair is key. ‘’Canola oil can moisturize and soften the hair,’’ Friese says.

Prevents dandruff: Canola oil can be helpful in treating and preventing dandruff, an effect that can help avoid related issues, as well. Severe dandruff can cause a person to scratch their scalp so hard that they might injure it and/or cause repeated inflammation in the hair follicles, which can reduce or even stop hair growth.4 Friese agrees with the power of canola oil, adding that it also ‘’contains anti-inflammatory compounds.’’

Minimizes hair loss: ‘’Consuming vitamin E, as well as applying it topically, can minimize oxidative stress on the scalp so your hair can grow properly,’’ Friese says. Reslan also agrees with canola oil’s ability to rejuvenate hair. ‘’Vitamin E is one of the most essential antioxidants for healthy hair growth, as it works to minimize hair loss,’’ she says.

Can provide UV protection: Most of us link sun damage to skin, but hair can also be damaged by the sun’s UV rays. Although experts question whether SPF is necessary for hair, being aware of the potential impact those warmer days can have is important. Friese says that even though the oil your hair naturally produces can protect it from the sun, canola oil ‘’may be helpful in providing UV protection.’’

Increases shine: Saturated and unsaturated fatty acids make up 85% of hair’s lipid content. Lipids are responsible for increasing and influencing shine in hair.5 ‘’Canola oil can calm down frizz and create shine,’’ Friese says.

Treats dryness: Canola oil is a hydrating ingredient, so it can repair damage caused by dryness. It can also protect hair from external factors like pollution and dry weather conditions. ‘’Oil treatments may help hydrate the strands and scalp. It is usually more effective to apply oils to dry hair since oil repels water,’’ Dr. Phipps says. She adds that dry oils are generally safe to apply to hair, but it’s important to adopt a less-is-more approach: ‘’Oils can weigh down hair, which can make it tough to rinse out, especially if your hair is fine or short.’’

Hair Type Considerations

Canola oil generally works on most hair types, but to reap its full benefits, understanding your hair’s porosity can help when deciding which type of treatment to use. The porosity of your hair affects how well oils and moisture are able to pass through your cuticles.6 Low-porosity hair thrives on lightweight oils, as the cuticles on the hair shaft are tightly sealed. As canola oil is lightweight, it’s perfect for low-porosity hair, as it won’t weigh it down. Canola oil may also benefit high-porosity hair, which can look and feel dry.

For anyone who wants to use canola oil with the intention of revitalizing dry and damaged hair, it’s worth a try. Oil treatments may have benefits for dry hair, but if your scalp is sensitive (be aware that scalp health and hair health are two completely different things), it may be best to avoid using canola oil on your hair.7 ‘’Test oils before you use them in the event of an allergic reaction—if you have an allergy to a product that oil is sourced from, avoid it altogether,’’ Dr. Phipps advises. When you apply oil on your hair, it will come into contact with the skin, and canola oil is no exception.8 To test a dry oil on your hair, Dr. Phipps recommends applying it to a small section of your skin before applying it on your scalp. If you don’t develop an allergic reaction within 24 hours, it’s likely to be safe.

Canola oil is safe to mix with other oils, but if you’re using it by itself, don’t apply large quantities if your scalp tends to get oily. ‘’Excess oil can clog pores on your scalp, which can prevent your hair follicles from growing normally,’’ Dr. Denning says.

How to Use Canola Oil for Hair

There are a number of ways to experience the benefits that canola oil has to offer. ‘’I would recommend using canola oil as a pre-poo treatment,’’ Friese says. ‘’This will help with circulation and cellular rejuvenation.’’

  • As a pre-shampoo treatment: ‘’For hair growth, mix canola oil with rosemary or lemongrass oil and massage into the scalp for about 20 minutes before shampooing,’’ Friese says.
  • As a hair mask: ‘’To increase your hair’s moisture levels, mix canola oil with coconut oil and use it as a hair mask,’’ Friese says. ‘’I recommend leaving it on for about 30 minutes before shampooing.’’
  • As a hair treatment: ‘’I recommend using one to two tablespoons of canola oil to saturate the ends and scalp, depending on the length of your hair. Massaging the oil onto dry hair and then covering it with a warm towel or shower cap for up to 15 minutes will allow the oils to better penetrate into the hair shafts and scalp,’’ Dr. Phipps says. ‘’I also recommend using a wide tooth comb to evenly distribute the oil all the way through your strands before rinsing thoroughly.’’ If your hair is thick, you may need to increase the amount of oil accordingly.
  • As a leave-in conditioner: ‘’To help combat dry hair issues, canola oil can be mixed with warm water and sprayed into hair. Leave it in like a leave-in conditioner to provide extra moisture and protect the hair from damage,’’ Friese says.
