Coconut oil has a unique composition of medium-chain fatty acids and the ability to penetrate the hair shaft, so it can effectively moisturize, strengthen, and even promote hair growth. However, it’s not for all hair types.
I always wondered why I wasn’t seeing these benefits of using coconut oil on my hair. Well, I found out I have low-porosity hair, and heavier oils like coconut oil don’t get along with my hair.
In this article, I aim to demystify the relationship between coconut oil and low-porosity hair, exploring its benefits, drawbacks, and alternative options.

What is low porosity hair?
Low porosity hair refers to hair with cuticles that lay flat and tightly packed together, hindering the penetration of moisture and nutrients.
This hair type often feels dry despite using conditioning products and is prone to product buildup.
Consequently, individuals with low porosity hair face challenges in maintaining hydration and moisture balance.
Is coconut oil good for low porosity hair?
As someone with low porosity hair, I’ve found coconut oil to be a bit tricky. While it’s a popular choice due to its moisturizing properties, it can be heavy and difficult to absorb for low-porosity hair types. Personally, I’ve noticed that coconut oil tends to sit on top of my hair rather than penetrating deeply, which can lead to buildup and weigh my hair down.
This is because coconut oil is a heavy oil, which can be problematic for low porosity hair types. Due to the tightly closed cuticles characteristic of low-porosity hair, heavy oils like coconut oil may sit on the hair’s surface without proper absorption. This can lead to buildup and weigh down the hair, resulting in a lack of volume and potential greasiness.
However, that doesn’t mean those with low porosity hair should never use coconut oil. Some individuals with low porosity hair find that coconut oil works well for them, especially when used as a pre-shampoo treatment or in combination with other ingredients that can help open the hair cuticles, such as heat or steam.
What happens if you put coconut oil on low porosity hair?
When applied to low porosity hair, coconut oil may not penetrate the hair shaft effectively, leading to limited moisturization and potential buildup.
Instead of benefiting from the nourishing properties of coconut oil, individuals with low porosity hair might find their strands feeling coated, heavy, and even greasy.
Here’s what happens:
Limited absorption: Due to the nature of low porosity hair, the cuticles are tightly packed, making it difficult for moisture to penetrate. Coconut oil, being a heavier oil, may struggle to penetrate the hair shaft effectively. Instead, it tends to sit on the surface of the hair, potentially leading to a greasy or oily appearance without providing much hydration.
Buildup: Because coconut oil isn’t easily absorbed by low-porosity hair, repeated use can lead to buildup. This buildup can weigh down the hair, making it appear limp and greasy. It may also interfere with the hair’s natural ability to retain moisture, exacerbating dryness over time.
Potential for frizz: If coconut oil isn’t properly absorbed and sits on the hair’s surface, it can contribute to frizz, especially in humid environments. The oil may attract moisture from the air, causing the hair to swell and frizz.
Protein sensitivity: Coconut oil contains proteins that can strengthen the hair shaft. However, individuals with low porosity hair may be more prone to protein sensitivity, leading to stiffness and brittleness rather than improved elasticity.
Difficulty washing out: Coconut oil can be stubborn to wash out, especially for low-porosity hair. It may require multiple washes with a clarifying shampoo to completely remove the oil and any buildup it leaves behind.
Which oils are best for low porosity hair?
While coconut oil may not be the ideal choice for low-porosity hair, several alternatives offer similar benefits without the risk of buildup.
I’ve had better results with lighter oils like argan or grapeseed oil, which are easier for my low porosity hair to absorb. These oils still provide moisture without leaving a heavy residue.
Additionally, using a clarifying shampoo occasionally helps to prevent buildup from heavier oils like coconut oil.
Here are some of the best oils to use for low porosity hair:
- Argan oil
- Grapeseed oil
- Sweet almond oil
- Jojoba oil
- Apricot kernel oil
- Rice bran oil
So, is coconut oil good for low porosity hair?
Coconut oil is not the best choice for low-porosity hair. This hair type tends to have difficulty absorbing moisture due to the tightly closed cuticles. Coconut oil has a relatively large molecular structure, which can make it difficult to penetrate the hair shaft in such cases.
It’s essential to pay attention to how your hair responds to coconut oil. If it makes your hair feel dry or coated, it might not be the best option for you. In such cases, lighter oils like argan oil or grapeseed oil might be more suitable.
FAQs
When applied to low porosity hair, coconut oil may sit on the hair’s surface, leading to potential buildup and lack of absorption.
Lighter oils such as argan oil, grapeseed oil, and almond oil are best for low porosity hair due to their ability to penetrate the hair shaft without causing buildup.
Coconut oil is considered heavy, which may not be ideal for low porosity hair types.
Lighter oils, leave-in conditioners, and water-based products are effective moisturizers for low porosity hair, helping to hydrate without weighing down the strands.
