What is macadamia oil?

When it comes to hair and general health care, a new product on the rise in terms of popularity is that of macadamia oil. This powerful and intense product has become a go-to choice for many people who are looking for a health product that they could start using more or less right away. It’s become a common choice in health and skin care, but is it really any good for our hair?

Taken from the macadamia tree itself, this is one of the most interesting looking oils. It’s got a clear, almost yellow appearance to it. 

If you look around, there are many links talking about the benefits of macadamia oil for hair. Is it the truth, though? Let’s take a closer look at what benefits you might get by using this particular kind of hair product. 

Macadamia Oil For Hair: Benefits

While much more research is needed into macadamia oil, it’s linked to a whole range of healing solutions. This particular oil has become a major ingredient that is used in health and hair care today. But is there any realism in the claims that it can make your hair stronger and smoother for the long-term? Let’s take a look. Some of the suggested benefits that come from using macadamia oil for hair include:

  • Added fatty acids and potassium; both which are vital ingredients for natural hair smoothing.
  • Like other oils, macadamia oil has been linked with rapid follicle penetration, boosting intake.
  • It’s known to use its fatty acids to help bind together hair shafts, improving durability.
  • Regular usage of macadamia oil has been linked (but not proven) to make hair shinier.
  • Those with curly hair might also find that macadamia oil makes their hair easier to control.

Macadamia Oil Side Effects

The only real side-effects that are being linked to macadamia oil at the time of writing include allergic reactions. If you are someone who is allergic to tree nuts, then you might suffer from an allergic reaction to the oil being used. It’s not been linked to any major long-term issues, though, so as long as you speak to a medical professional beforehand you should have no problem at all with using macadamia oil for hair today.

As ever, speak with a medical professional and, if you are given the all-clear, try a small spot of the oil on your forearm. If you notice any kind of reaction, then you should go back to your doctor for further testing.
