6 Benefits of Argan Oil for Hair

The wisdom of using argan oil for hair care has been passed down for centuries in the Souss Valley in southwestern Morocco. Every full-moon night, local Berber women gather under argan trees, manually crack open the harvested argan nuts, and extract the precious argan oil through grinding with stone mills and boiling in clay pots. This orange-yellow liquid is not only used for skin care but also passed down from generation to generation as a secret hair care remedy—brides need to nourish their hair with argan oil for 40 days before their wedding to ensure that their hair flows as smoothly and shines as brilliantly as a waterfall on the wedding day. Today, this hair care wisdom has been perfectly confirmed by modern science.

Derived from the nuts of Moroccan argan trees (Argania spinosa), argan oil has a centuries-old history of traditional use in the region and is known as “liquid gold”. Modern scientific research has confirmed that it is rich in unsaturated fatty acids, vitamin E, and polyphenols, demonstrating outstanding value in the field of hair care and becoming a star ingredient in natural hair care products.

Core Benefits

The comprehensive hair care value of argan oil lies in the synergistic effect of its unique ingredient composition and multiple mechanism of action. As a natural vegetable oil, argan oil is not only rich in unsaturated fatty acids, vitamin E, and polyphenols, but modern scientific research has also confirmed its outstanding performance in the field of hair care. This “liquid gold” can improve hair health from multiple dimensions, including deep nourishment, repairing damage, reducing frizz, improving the scalp environment, enhancing toughness, and providing antioxidant protection, thus forming a comprehensive hair care system.

1.Deep Moisturizing and Nourishment

• Mechanism of Action:The deep moisturizing and nourishing effects of argan oil on hair stem from its unique ingredient composition. Among these ingredients, unsaturated fatty acids (with oleic acid and linoleic acid accounting for over 80%) form a protective film on the surface of hair strands, effectively preventing moisture evaporation. Vitamin E (containing 30-60 mg per 100 grams) penetrates deep into the hair cuticles, repairs damaged lipid layers, and enhances the hair’s natural moisture-retention capacity. This dual moisture-locking mechanism makes argan oil an ideal care choice for dry hair.
• Scientific Data:Experimental data from local Moroccan research institutions in 2023 showed that hair care products containing 5% argan oil can increase hair moisture content by 42%, and the effect can last for more than 72 hours. A 2024 study published in the Journal of Cosmetic Science (U.S.) further confirmed that people who use argan oil regularly have a 58% lower rate of hair moisture loss compared to the control group. It is particularly suitable for hair care in dry climates.
• Applicable Scenarios:For daily care, it is recommended to choose hair care products containing 5-10% argan oil, such as shampoos, conditioners, or leave-in conditioners. These products can continuously provide nutrients to the hair during daily cleansing, preventing dryness and damage. When using, be careful to avoid the scalp and focus on caring for the mid-lengths to ends of the hair. The daily maintenance effect of argan oil on hair will gradually become apparent with prolonged use.

2.Repair Damaged Hair

• Mechanism of Action:The effect of argan oil on repairing damaged hair is mainly achieved through two pathways: Polyphenols promote keratin synthesis, filling in the structural defects of damaged hair strands; at the same time, unsaturated fatty acids penetrate the gaps between hair cuticles, restoring the smoothness of the hair surface. Additionally, the synergistic effect of vitamin E and sterols strengthens the disulfide bonds in hair, enhances the toughness and breakage resistance of hair strands, and improves damaged hair at the molecular level.
• Scientific Data:A 2024 study published in the International Journal of Cosmetic Science (UK) found that linoleic acid in argan oil can increase the extensibility of hair fibers, boosting the elasticity recovery rate by 41%. Experiments conducted by the Shiseido Research Center (Japan) showed that hair masks containing argan oil can increase the tensile strength of hair by 29% and the elongation at break by 23%. These data confirm that the hair-strengthening effect of argan oil is scientifically grounded, making it particularly suitable for repairing damaged hair.
• Applicable Scenarios:For severely damaged hair, it is recommended to use 100% pure argan oil for deep conditioning. It can be used as a hair mask 1–2 times a week: Take an appropriate amount of argan oil, rub it between your palms to warm it up, apply it evenly to dry hair, wrap your hair with a shower cap for 30 minutes, then rinse thoroughly. This intensive care allows the repairing components of argan oil to fully penetrate the hair, significantly improving split ends and breakage issues.

3.Reduce Hair Frizz

• Mechanism of Action:The effect of argan oil on reducing hair frizz is based on its unique physicochemical properties. Its polar lipid components can neutralize static electricity on the hair surface, while its oil structure can spread evenly across the surface of hair strands to form a smooth reflective layer. This enhances hair shine while reducing flyaways, keeping the hair smooth and manageable even in high-humidity environments.
• Scientific Data:A 2023 test conducted by the German Society of Dermatology confirmed that after using hair care products containing argan oil, the static voltage of the hair dropped from 1800V to 320V. This significant anti-static effect directly reduces hair frizz and flyaways, making hairstyles easier to style and maintain.
• Applicable Scenarios:Using argan oil-infused hair oil before styling can effectively protect hair from heat damage and reduce frizz. Take 2-3 drops of argan oil, rub it evenly between your palms, and gently apply it to semi-dry hair before using a hair dryer or hair straightener. The heat protection effect of argan oil on hair can reduce heat damage by more than 50%, while also increasing the longevity and shine of the hairstyle and reducing frizz caused by heat styling.

4. Improve Scalp Health

• Mechanism of Action:Argan oil exerts a significant improving effect on the scalp environment, which is essential for hair growth. Its antibacterial and anti-inflammatory properties help balance the scalp microbiota, reduce dandruff formation, and at the same time soothe scalp sensitivity and inflammatory reactions. Additionally, the vitamin E and polyphenols in argan oil can nourish the scalp, enhance the scalp barrier function, and create a favorable environment for healthy hair growth.
• Scientific Data:A study published in the Journal of the European Academy of Dermatology and Venereology (JEADV) in 2023 showed that a scalp serum containing 5% argan oil can reduce dandruff count by 63%, and the effect can last for 8 weeks. Experiments conducted by the Korean Society for Investigative Dermatology also indicated that after 4 weeks of continuous use of argan oil, patients with seborrheic dermatitis experienced a 58% reduction in the area of scalp erythema and a 72% decrease in pruritus scores. A healthy scalp environment provides a foundation for strong hair growth.
• Applicable Scenarios:It is recommended to carry a small bottle (10-15ml) of argan oil when traveling, as it can address various emergency hair issues, including improving scalp health. The multi-effectiveness of argan oil for hair makes it a must-have hair care item for travel—one bottle can meet hair needs in different environments. Especially when climate changes cause scalp sensitivity or dryness, it can effectively soothe and balance the scalp environment.

5. Enhance Hair Toughness

• Mechanism of Action:The effect of argan oil on enhancing hair toughness stems from its strengthening of the hair fiber structure. Unsaturated fatty acids penetrate the interior of hair strands and bind with keratin to form a more resilient structure; meanwhile, vitamin E protects the proteins in hair from free radical damage, maintaining hair’s elasticity and strength. This dual action enables hair to better resist mechanical damage caused by daily combing and styling.
• Scientific Data:Multiple studies have confirmed the role of argan oil in improving hair’s mechanical properties. A 2024 study published in the International Journal of Cosmetic Science (UK) found that argan oil can increase the extensibility of hair fibers, boosting the elasticity recovery rate by 41%; experiments conducted by Shiseido Research Center (Japan) also showed that hair masks containing argan oil can increase hair’s tensile strength by 29%. These data fully demonstrate the scientific basis for argan oil’s ability to enhance hair toughness.
• Applicable Scenarios:For people who frequently dye, perm, or style their hair, it is recommended to use hair care products containing argan oil 2–3 times a week to enhance hair toughness and reduce breakage. The protective effect of argan oil on hair not only repairs existing damage but also prevents future damage, making it particularly suitable for long-term use by individuals who need to process their hair frequently.

6. Antioxidant Protection

• Mechanism of Action:The antioxidant protective effect of argan oil on hair is mainly achieved through its rich content of vitamin E and polyphenols. These antioxidant components can neutralize free radicals, reduce the damage caused by oxidative stress to hair and scalp, protect melanocytes, delay the process of hair aging and graying, and at the same time prevent hair damage from environmental pollution and ultraviolet rays.
• Scientific Data:Multiple studies have confirmed the antioxidant capacity of argan oil. The journal Pigment Cell Research stated in 2024 that long-term use of argan oil can reduce the proportion of newly grown gray hair by 21%. These antioxidant effects not only protect the color and luster of hair, but also maintain the structural integrity of hair and delay the hair aging process.
• Applicable Scenarios:For daily care, it is recommended to choose hair care products containing 5-10% argan oil, such as shampoos, conditioners, or leave-in conditioners, to obtain continuous antioxidant protection. Such products can continuously provide antioxidant components to hair during daily cleansing, prevent free radical damage, and long-term use can maintain the youthful state and healthy luster of hair.
