Benefits of Macadamia in Hair Products
When a product contains macadamia, most of the time this will be in the form of macadamia nut oil, which is a common carrier oil used with essential oils.
Macadamia nut oil comes from the nuts of the macadamia trees which are grown in Australia and New Zealand as well as South Africa, Kenya, Malawi, Israel, Mexico and other areas of Central and South America. They can also be found in Florida, California and Hawaii. To make the oil, mature macadamia nuts are harvested, husked and dried before the oil is extracted.
Provides Essential Nutrients
Macadamia nuts are popular as a healthy snack as well as an ingredient in hair products and this is due to the large number of nutrients that can be found within the nut. The oil alone contains iron, phosphorus, B complex vitamins and calcium. It also contains large amounts of palmitoleic acid which is an Omega 7 fatty acid.
Additionally, macadamia nut oil contains a range of proteins and vitamin E which can help repair damage and soften the shafts of hair. This makes the oil especially beneficial when used in shampoos, conditioners and styling aids. Topically providing nutrients and vitamins can have long-term benefits for growth, strength color, and minimizing damage and frizzy, fly-away styles.
Because of the nutrients it contains, particularly the proteins, it can help prevent breakage from occurring. When hair is damaged the overlapping layers that form its cuticle will be separated, leaving the inner layers unprotected.
Macadamia nut oil, however, can penetrate the scalp as well as follicles and increase the elasticity and strength. Additionally, the proteins in the oil can help repair some of the damage done to the proteins that make up the hair itself.
Frizz is an incredibly common phenomenon for those with curly or wavy shafts and this problem can increase if beauty products are used incorrectly or during humid weather.
Some frizz is due to breakage while other is simply due to humidity affecting how the cuticle layers lie on top of the shaft. Products that contain macadamia are able to coat the entire shaft using nourishing vitamins and fatty acids. This process helps eliminate frizz by returning the cuticles and the rest of the shaft to their normal structure. This light coating also provides a protective layer reducing the amount of water vapor (humidity) that is absorbed by the follicle shaft, and thus frizzy hair
can be controlled more readily.
Hydrates and Moisturizes
One of the components of macadamia mentioned above, palmitoleic acid, is found in our bodies and works to replenish moisture that is lost in the hair shaft, as well as the skin. However, the amount of palmitoleic acid that is produced naturally decreases with age so products that contain it in the form of macadamia nut oil must be used to restore the acid to the normal quantities and hydrate hair in the process.
Absorbs Free Radicals
Macadamia contains several antioxidants and these include vitamin E, as well as squalene. These antioxidants are responsible for protecting the hair shafts, as well as skin and other cellular structures, from free radical damage. If left unchecked, free radicals can alter the cellular makeup of proteins or other parts of the shaft, even altering their DNA. By preventing and removing free radicals, however, the antioxidants in macadamia ensure strands remain healthy and in their original state.
Macadamia and Macadamia oil has many benefits for hair products. Besides providing topical nutrition for added hair health, its natural oils provide increased hydration and daily protection for the frizz and the effects of humidity. It has found its way into shampoos, conditioners and many styling aids - including those developed as deep treatments for damaged and breaking hair.
