What are natural oils?

In case you're not familiar with oils and their benefits, an oil can be defined as a fatty lipid compound of natural or synthetic origin that is liquid at room temperature. 

The word "oil" may also refer to any substance that flows or oozes easily – which can be anything from petrolatum jelly to essential plant oils. 

Oils have a variety of characteristics and advantages, depending on their composition. Plant-derived oils, for example, are typically high in nutrients that help moisturize and nourish hair and skin. 

Natural Oils That Penetrate Hair

Hair-specific oils, like the ones we're discussing today, are usually derived from natural ingredients and aim to penetrate the hair shaft with their nutrient-rich goodness. 

From protecting your hair from heat damage to fighting dandruff, every oil is different and has a range of benefits. 

Keep on reading and learn more about the top 5 hair penetrating oils that, along with being great for your hair, can greatly benefit your skin as well!

Olive Oil

Olive oil is a timeless favorite when it comes to oils! Not only is it the base of many pre-poo treatments, but it also penetrates the hair shaft with its high content of monounsaturated oleic acid. 

When applied to the scalp and hair, olive oil keeps moisture locked in so that your tresses are soft and supple.

The oil contains antioxidant properties and a high content of vitamin E which is known to be a great moisturizer for the scalp while also preventing premature graying and hair loss.

Olive oil can be used as both a pre-poo treatment or even as a hot oil treatment. 

Argan Oil

The Moroccan oil that has transformed the hair care industry! I know you've heard so many great things about argan oil, but this miracle product really is all it's cracked up to be. 

Like olive oil, argan oil penetrates the hair shaft with its high content of vitamin E and unsaturated fatty acids. 

The high concentration of antioxidants in argan oil makes it a great treatment for strengthening your hair by delivering nutrients straight to the heart of each strand.

Argan also contains squalene (a natural antioxidant) which helps lock in moisture and treat dry scalp conditions like dandruff or psoriasis. 

You can find argan oil at most beauty supply stores but if you want to buy online, make sure to look up a trusted seller.

Coconut Oil

If you're not already familiar with the amazing benefits of coconut oil, let me just say – you've been missing out! 

Coconut oil has so many uses and naturally penetrates the hair shaft. You can use it in a hot oil treatment, but you can also use it as your daily moisturizer to provide lasting hydration to dry tresses. 

Vitamin E keeps skin soft while the lauric acid sinks into the hair shaft to soften and hydrate. Use 2-3 tablespoons in your carrier oil for an overnight treatment or keep coconut oil on hand as a daily moisturizer.

Castor Oil

Next, is castor oil. This thick, sticky yellow liquid penetrates hair like nothing else! As stated earlier, the fatty acids promote hair growth by strengthening each strand. 

Castor oil also moisturizes dry hair, so luscious locks are instantly created! Just apply two to three tablespoons of castor oil to your tresses after shampooing and conditioning for a deep conditioning session that will leave you with moist, healthy tresses.

Jojoba Oil

Jojoba oil is another popular penetrating oil. It's an antioxidant, anti-bacterial, and anti-fungal agent that moisturizes your tresses to the extreme! 

Jojoba oil is effective at keeping tresses healthy because it penetrates deeply into each strand to strengthen them from the inside, preventing breakage.

Jojoba oil contains fatty acids and vitamin E, which encourage hair growth and protect your hair from free radicals, which can cause hair damage. 


You can use jojoba oil as a pre-poo treatment or hot oil treatment; just use 2-3 tablespoons of jojoba oil to moisturize each strand.

Tea Tree Oil

Tea tree oil is a natural antiseptic and antimicrobial agent that can help with dandruff when applied topically. It penetrates the hair shaft quickly to moisturize dry hair while preventing build-up on your scalp. 

In addition to that, tea tree oil contains anti-inflammatory and repairing properties which makes it great for damaged hair. 

If you've just had a bad dye job, tea tree oil is a great option for quickly restoring health to your tresses. Just make sure you dilute it properly in a carrier oil to prevent scalp burns.

Grapeseed Oil

Grapeseed oil is a light oil that can penetrate the hair shaft beautifully! Vitamin E keeps skin soft while the antioxidants soak into your tresses to prevent damage. 

Grapeseed oil is a great choice for repairing damaged hair, preventing frizz, and keeping split ends away!

Use 2-3 tablespoons in an overnight deep conditioning session or simply apply directly to the scalp daily to hydrate dry tresses.

Rosemary Oil

Rosemary oil has been used for centuries to treat scalp conditions like dandruff, dermatitis, and psoriasis because it penetrates the hair shaft so effectively. 

Just make sure you dilute it with a carrier oil to prevent scalp irritation and remember that rosemary oil should NOT be used on children because of its possible toxicity.

In conclusion, natural oils are an excellent option for all naturalists! The oils we've talked about in this article penetrate deep into the hair shaft to moisturize dry tresses while preventing damage from breakage and free radicals that cause color fading.

Just make sure you always pick 100% pure essential oils like the ones WOW Skin Science offers. 

Try one or more of the oils listed above to achieve healthy, hydrated tresses – and don't forget that your favorite natural oil can be used for a killer hot oil treatment!
