Hair porosity plays a crucial role in determining the effectiveness of hair care products, especially when it comes to oils.
Low porosity hair tends to have a tightly sealed cuticle layer, making it more challenging for moisture and nutrients to penetrate.
So, while many oils boast various benefits for different hair types, not all are suitable for those with low porosity hair.
In this article, I’ll explore the drawbacks of using certain oils on low-porosity hair and provide alternatives for a healthier hair care routine!

What should I avoid with low porosity hair?
Low porosity hair has cuticles that are tightly packed, making it more difficult for moisture to penetrate the hair shaft. To care for low porosity hair effectively, here are some things you should avoid:
- Heavy products: Avoid using heavy products that can weigh down your hair and make it look greasy. Instead, opt for lightweight, water-based products that can be easily absorbed.
- Excessive protein: While protein is essential for hair health, too much of it can make low porosity hair feel stiff and dry. Use protein treatments sparingly and focus on moisturizing products.
- Heat damage: Using excessive heat on low porosity hair can cause damage. Be cautious with heat styling tools and always use a heat protectant before styling.
- Overwashing: Low porosity hair tends to repel water, so it doesn’t get as dirty or oily as quickly as other hair types. Overwashing can strip the hair of its natural oils, leading to dryness. Aim to wash your hair as needed, but not excessively.
- Silicone buildup: Silicone-based products can create a barrier on the hair shaft, which may be challenging to penetrate for moisture. If using products with silicones, clarify your hair periodically to prevent buildup.
- Skipping deep conditioning: Deep conditioning is crucial for low porosity hair to help open the cuticle and allow moisture to penetrate. Don’t skip this step in your hair care routine!
5 Low porosity hair oils to avoid
1. Coconut oil
While coconut oil is praised for its numerous benefits, it may not be the best choice for individuals with low porosity hair. The molecules in coconut oil are relatively large, making it challenging for them to penetrate the tightly closed cuticles of low porosity hair. As a result, coconut oil may sit on the hair’s surface, leading to a greasy feel and potential buildup over time. If you have buildup, here’s how to detox your hair.
2. Olive oil
Olive oil is another commonly used oil in hair care, but it may not be the ideal option for low porosity hair. This oil is rich in oleic acid, which can make it heavy and difficult to absorb for hair with tightly sealed cuticles. Using olive oil on low porosity hair may leave it feeling weighed down and less responsive to styling.
3. Castor oil
Castor oil has a VERY thick consistency and moisturizing properties but can be too heavy for low porosity hair. The thickness of castor oil may make it challenging to penetrate the cuticle layer, potentially leading to buildup on the hair shaft. Instead of promoting moisture retention, it may create a barrier that hinders the hair’s natural hydration process.
4. Shea butter
While not technically an oil, shea butter is a popular ingredient in many hair products, and it may not be the best choice for low porosity hair. Shea butter is rich and dense, and it can be challenging for low porosity hair to absorb. Instead of enhancing moisture, shea butter may leave a residue on the hair, causing it to feel greasy and weighed down.
5. Mineral oil
Mineral oil is a petroleum-derived product that is often used in hair care for its ability to create a barrier on the hair shaft. However, for low porosity hair, this barrier can be counterproductive. Mineral oil may prevent moisture from entering the hair shaft, leading to dryness and potential breakage over time.
Alternatives for low porosity hair
Choosing the right hair oil is a personal journey, and what works for one person may not work for another. For those with low porosity hair, it’s essential to find lightweight oils that can penetrate the cuticle and provide much-needed moisture.
Experimenting with different oils and observing how your hair responds is the key to developing a tailored hair care routine.
While the oils mentioned above may not be the best fit for low porosity hair, there are plenty of alternatives, such as argan oil, grapeseed oil, and sweet almond oil, that can offer the nourishment your hair needs without the risk of excessive buildup.
FAQs
With low porosity hair, you should avoid heavy products and ingredients that may cause buildup, as the cuticle layer is less porous and prone to trapping substances. Regularly clarifying and using lightweight, water-based products can help maintain healthy hair.
Coconut oil can be challenging for low porosity hair, as it may sit on the surface without being fully absorbed. Instead, opt for lighter oils like argan or grapeseed, which are more easily absorbed by the hair shaft.
Rosemary oil can be beneficial for low porosity hair as it stimulates blood circulation in the scalp, promoting hair health. However, it’s essential to use it in moderation and pair it with a light carrier oil. Too much oil can lead to buildup, particularly on low porosity hair.
Vitamin E oil can be beneficial for low porosity hair, as it helps nourish and moisturize the hair shaft. However, using it sparingly is key, as excessive amounts may contribute to buildup. Incorporating it into a balanced hair care routine can provide added moisture and protection.
