Macadamia oil, extracted from macadamia nuts, is filled with nutrients that are claimed to improve hair quality and stimulate hair growth. While it may not be as popular as other oils, it holds its own place in the hair care world. It is used in many hair care products, like shampoos and conditioners. Read on to find out how using macadamia oil can transform your tresses!

How Does Macadamia Oil Help Hair And Scalp?

Anecdotal evidence suggests that using macadamia oil is extremely beneficial for the hair and scalp. It is said to improve hair texture, structure, and elasticity. It may also increase hair shine, provides frizz control, and repair damaged hair. But, does science agree with these benefits?

1. May Improve Hair Strength

Macadamia oil contains a high amount of lipids (fatty acids) (1). Hair is made up of lipids. Since macadamia oil contains lipids, it may help strengthen your hair and improve its texture and quality.

2. Contains Essential Nutrients

Macadamia oil contains fatty acids, tocopherols, and squalene (1). Tocopherols have antioxidant properties that protect the hair from damage. Squalene is thought to be the protective agent in sebum. It may even help in sebum production. It also has antioxidant properties, which offer UV protection (1).

3. May Promote Minoxidil Absorption

The oleic acid in macadamia oil may make the scalp better absorb minoxidil (a hair growth medication) (2). Minoxidil is often used to promote hair growth.

4. May Improve Hair Health

Macadamia oil contains fat, protein, carbohydrates, and fiber that may nourish your hair and improve its health (3).

5. Increased Collagen Production

Macadamia oil contains essential amino acids (4). Amino acids help in collagen production (5). Collagen is a protein that contains keratin, which strengthens the hair. Increased collagen production may help improve hair elasticity. Amino acids can also balance pH levels and improve hydration.

7. Moisturizes Your Hair

Macadamia oil is a triglyceride oil and contains up to 80-84% of monounsaturated fatty acids (8). This means it can be used as a hair moisturizer.

8. Offers UV Protection

9. May Stimulate Hair Growth

Macadamia oil is a great natural source of vitamin E (3). This vitamin can be used to stimulate hair growth. Vitamin E is known to improve blood flow. It also has antioxidant properties that can help prevent hair loss and hair damage.

10. Improves Hair Smoothness

Due to its high fat content macadamia oil, penetrates the hair easily and smoothens it (3). This can also help prevent frizz and boost hair shine.

11. May Improve Hair Manageability:

Macadamia oil is said to help detangle hair, which makes it easier to tame and style.

What Are The Nutrients Found In Macadamia Oil

Macadamia nut oil contains oleic acid, palmitoleic acid, and tocopherols. It is enriched with 80-84% of monounsaturated fatty acids, which makes it ideal for moisturizing hair. It also contains polyunsaturated fatty acids like linoleic and linolenic acids, which may help improve hair health (3).

Squalene – which is present in sebum – and campesterol and stigmasterol – which may strengthen hair – are also found in this oil. Other nutrients found in macadamia oil include calcium, magnesium, sodium, potassium, niacin, phosphorus, and folate (3). Research shows that a deficit in these nutrients may cause hair loss (9).

Now that you know all the hair benefits offered by macadamia oil, let’s check out how to use it!

How To Use Macadamia Oil For Hair Growth

Apply warm macadamia oil to your hair and cover it with a shower cap. Leave it on for at least 30 minutes. You can also leave it on overnight. The high fat content in macadamia oil moisturizes your hair.
  1. Hair Masks: You can mix macadamia oil with other natural ingredients like egg, yogurt, banana, and papaya to create homemade hair masks. These masks nourish your hair with nutrients and improve the hair texture.
  1. Conditioning Shampoos: You can add macadamia oil to your regular shampoo to make it moisturizing. If you have dry hair, doing this will prevent your shampoo from stripping away its natural oils and leave it healthy.
  1. Finishing Product: You can use a few drops of macadamia oil to add shine to your hairstyles and prevent flyaways or stray hair. It can also be used before heat styling your hair to protect it from severe heat damage.
