Straight hair will never go out of style! Many people prefer straight hair because of its classic, smooth, and ultra-chic appearance. Hair oils play an important role in the straightening process.

You have to be careful when choosing a hair straightening oil. Not all oil can make you achieve luscious straight hair. Plus, there are more options than ever which can be quite hard to choose from. 

For that reason, Lucky Curl is here to help you decide which oil is best for straightening hair. Let’s get moving!

Types of Hair Oils to Use When Hair Straightening

Argan Oil

Argan oil contains antioxidants and fatty acids which moisturize the hair naturally. It is one of the most famous hair oils around and many people have given it the nickname “liquid gold.”

This is a very light oil that is suitable for most hair types. It does not only straighten your hair but penetrates the hair follicles to repair cells and improves its finish. 

Jojoba Oil

The moisturizing properties of jojoba oil have earned it a place in countless hair care products over the years. Jojoba is made up of clever fats that can actually penetrate the outer layer of hair which also nourishes and repairs beneath the surface, making it an ideal treatment for dry hair. 

You can use it as an overnight treatment or use it as a raw ingredient on the ends of dry or chemically treated hair. As a result, you’ll get straighter and smoother hair!

Manketti Oil

In terms of fatty acids, manketti (also known as mongongo oil) is similar to argan oil. However, it contains more nutrient-rich fats and proteins, so it’s ideal for those of us who have damaged hair.

This type of oil can protect hair, make them stronger, softer, and shinier, and also shield your strands from external damaging factors. 

Castor Oil

Castor oil comes from the castor bean, which is packed with ricinoleic acid, known to reduce inflammation – great for dandruff sufferers. 

Castor oil and soybean are a great combo for hair treatment. Castor oil can prevent frizzy hair and soybean can straighten your hair. You can also use this treatment for DIY head massages to stimulate the follicles, which helps with hair growth.

Coconut Oil

With its many benefits for the hair, including calming frizz and helping to detangle, coconut oil is a true beauty multi-tasker. It contains fatty acids that coat the hair and prevent it from being stripped when you rinse it.

As a pre-shampoo treatment, you can apply organic coconut oil to your hair to restore its shine and texture.  If you have brittle hair, however, beware that using coconut oil too often can cause protein build-up, which will cause the hair to break.

Olive Oil

Your pantry’s olive oil works wonders on your hair, but be warned, in its purest form, it will only work on the surface of strands.

Olive oil has a larger molecule size than oils like almond oil and coconut oil. (Too large to penetrate the hair shaft!) A hair product containing oil is usually better than a raw form of the oil because the refined oil will do more for your straight hair. 


There are various choices for hair straightening oil. You should look deeper into each of your choices to ensure they’re safe for your hair.

Nevertheless, hair straightening oils work as long as you don’t overdo them. Apply a good amount of hair oil to your hair before and after hair styling. You can use the oil as a heat protectant and it also gives your hair strands a smoother finish after styling.
