MOISTURIZING Vs SEALING OIL; How To Use Them For Hair Growth


We all agree that all oils aren't created equal which is why we all have our day1 oils and our mmeh...' will do for now' oils. But the question is are you getting the best use out of them? or Are you using a sealing oil to moisturize and vice versa. Yep, I have done both.


Have you ever completed a full-on wash day or moisturizing routine, maybe a LOC method but a day/ hours later your curls are feeling dry? Well, you probably didn't seal up like you thought, because that was a moisturizing oil. 


Understanding the nature of oils is an important step to getting the best results out of your hair care routine. Here, we will help you differentiate between moisturizing and sealing oils also how best to use them in our hair growth journey.

How do moisturizing oils differ from sealing oils?

Moisturizing oils are able to penetrate hair shafts and moisturize while sealing oils cannot penetrate hair shafts but rather latch onto the hair fiber and form a protective thin film over hair strands.


To get a little sciency, the amount of triglyceride and short-chain fatty acids content of the oil determines its ability to penetrate the hair shaft. Fatty acids such as Lauric, Linoleic, Oleic, Palmitic, Capric, and Myristic acids can penetrate hair shafts.

Moisturizing Oils

We all know that moisture is key to reducing hair breakage and natural oils provide lasting moisture when applied. As they penetrate the hair shafts to moisturize the hair.


Top moisturizing oils for your hair care routine;


Coconut Oil





Avocado Oil





Olive Oil




COCONUT OIL is one of the best moisturizing oils that can penetrate hair strands easily in small quantities. And that is why a little goes a long way while using coconut oil, once a small amount of it penetrates and moisturizes the hair strands, the rest of it lay on the hair strands acting as a sealant, giving you the best of both worlds.


Coconut oil adds protein to hair strands, strengthening them and reducing hair breakage.

It is best used on water-spritzed hair (hydrated hair) or with a water-based leave-in.


AVOCADO OIL is high in fat, minerals, and antioxidants. It repairs dry, damaged hair and smooths hair cuticles to reduce frizz. It also provides the scalp with anti-oxidant protection.


Avocado oil is a natural source of biotin which aids to strengthen hair and prevent breakage.


OLIVE OIL contains vit.E and fatty acids that enable it to moisturize while adding shine to hair strands. It also reduces breakage and split ends.


Its squalane and Oleic acid contents soften hair, increasing hair manageability and making detangling hair easier while controlling frizz.


It is also best used with a water-based leave-in.

Other moisturizing oils include;

Argan Oil

Babassu Oil

Sunflower Oil

And Palm Kernel Oil.

Sealing Oils

Sealing oils otherwise known as sealants cannot penetrate hair strands but rather lay on the hair fiber to form a thin film that seals in the moisture already present in hair strands.


Some of the best sealing oils for your hair care routine;


JOJOBA OIL has a similar texture to the natural oil produced on the scalp (Sebum). It cleans the scalp and has anti-inflammatory properties that treat scalp issues such as dandruff.


GRAPESEED OIL is lightweight and best for thin-textured hair types as it does down weigh down hair after application. And also perfect if you need less fragrance in your oils.


JAMAICAN BLACK CASTOR OIL has a high viscosity, so it's best for thick, curly hair types. It coats your hair strands quite efficiently while also softening your curls.

How do you use moisturizing & sealing oils?

How to Use Moisturizing Oils




Pre-poo ensures that your curls are not stripped of their natural oil and moisture after shampoo. Applying oils to your curls before you shampoo, helps retain the hair moisture, softens hair to make detangling easier, and ensures your wash day ends with shiny curls.


Oil Rinse


The oil rinse hair routine involves conditioning curls with a conditioner and Oil mixture, leaving it on for a few minutes then washing off with water. It makes for easier detangling, frizz control, and a moisture boost for the hair strands.


How to Use Sealing Oils


To Seal


Apply your sealing oils after your leave-ins to lock in moisture and reduce water loss. It also reduces friction between hair strands, especially at the ends.


Control Frizz

Applying a sealant form a coat over hair strands thick enough to control frizz, especially with oils of thick viscosity.



We hope with this, you can understand your oils better and plan a suitable hair care routine to use them depending on your curl needs and texture.
