How I tested these oils for hair extensions

Now, I will explain how I tested different oils for hair extensions in a step-by-step, easy-to-understand manner. Continue reading for further details. 

Gathering supplies

First, I gathered all the supplies I needed for my oil testing experiment. This included the various hair extension oils I wanted to try, a notebook to take notes, and of course, my hair extensions.

Identifying criteria

Next, I thought about what was important in a hair extension oil. Was it about reducing frizz, adding shine, or promoting hair growth? Does its brand name famous for the quality of the product?

Prepping my hair extensions

I prepared my hair extensions by washing and drying them so they were clean and ready for testing. This way, I could start with a clean slate for each oil.

Applying the oils

One by one, I applied each oil to a different section of my hair extensions. I made sure to use the same amount of each oil so that the results would be fair and accurate.

After applying the oils, I observed how my hair extensions looked and felt. Did they feel softer, look shinier, or show any other noticeable changes? I took notes of these observations in my notebook. I repeated this process over several days or even weeks to see if there were any long-term effects or changes in the condition of my hair extensions.

Comparing the results

Finally, I compared all my notes and observations to see which oil performed the best according to my criteria. This helped me determine which oil I considered the “best” for my hair extensions.


   1. Should you put oil on hair extensions?

Yes, you can put oil on hair extensions. Using a small amount of hair oil can help keep your hair extensions soft and shiny. Be careful not to use too much, as it can make them look greasy. 

What oils should not be used for hair extensions?

Although I have mentioned the best hair oil for extensions, certain oils should be avoided, as they can damage or weigh down the extensions. These oils include:

  • Mineral oil: Mineral oil can make hair extensions greasy and heavy. It’s best to avoid this oil.
  • Olive oil (in excess): Olive oil can have a similar effect to coconut oil when overused, so it’s best to use it sparingly.
  • Castor oil (in excess): Castor oil is thick and can be challenging to wash out, so it’s best not to use too much on extensions.
  • Essential oils (undiluted): Some essential oils can be too strong for hair extensions when used undiluted, potentially causing damage.

   3. Can I put coconut oil on my extensions?

Yes, you can use coconut oil on your hair extensions, but remember to use it sparingly. Coconut oil can be quite heavy, so using too much may make your extensions greasy or weighed down. To avoid this, apply a small amount of coconut oil to the tips and lengths of your extensions and make sure to thoroughly wash and rinse them to prevent any buildup. 

Final Thoughts

Investing in high-quality hair extensions is a smart choice, and taking care of them is equally important. The best oil for hair extensions can make a significant difference in the longevity and appearance of your extensions.
