Choosing the best products for a low porosity hair care regimen is not easy. However, understanding the role low porosity hair may play in controlling the quality of your hair’s moisture levels can make a world of difference in having healthy hair.

Surprisingly, many naturalistas do not know they have low porosity hair. As a result, they are left tussling with hair that feels dry and moisture-deprived, despite their consistent usage of a “good” conditioner, avoidance of heat, and adherence with several other commandments from the natural hair community.

Take a seat and dive into this article. If you find yourself frequently going to battle with natural hair looks and feels dry, you may have low porosity hair.

What Does Low Porosity Hair Look Like?

You cannot always tell by just looking at hair whether it is high or low porosity. Occasionally, you have to take a few steps to test the porosity of your hair. Thankfully, many natural hair mavens who completed the journey ahead of us, have identified a few tried and true approaches for testing your hair porosity.

The Float Test

How do you know if you have low hair porosity? There are multiple ways to test for hair porosity. Our favorite method is the float test. To test for hair porosity, simply get a glass of water. Then, place a clean strand of your hair at the top of the water in the glass.

Low porosity hair will float at the top of the glass of water for quite some time before sinking to the bottom. Conversely, hair that immediately falls to the bottom has high porosity and demonstrates hair that is highly receptive to water and moisture.

If you find that your hair floats somewhere in the middle for a period, you have normal or medium porosity hair.

The Water Spritz Test

Another option is the water spritz test. This process is simple, as follows:

Lightly spritz water on a small section of your hair.
Observe how your hair reacts. If the water beads on the surface instead of being absorbed, it suggests low porosity.

Observation of Hair Behavior

Additionally, you can look for basic signs of low porosity hair, including:

How long it takes to dry
Resistance to chemical treatments and conditioning, as it doesn’t absorb products easily.

The Slip and Slide Test

Finally, you can perform the slip-and-slide test.

Slide your fingers up a hair strand towards the scalp.
If it feels bumpy, it’s likely high porosity. If it’s smooth, it indicates low porosity, as the cuticles are flat and tight.

Can You Use Heat on Low Porosity Hair?

The short answer to this question is yes –you can use heat on low porosity hair. It has to be a specific type of heat for best results. Heat helps to open your cuticles. Thus, heat is your biggest ally under the right circumstances. Heat steamers or hooded dryers are two items you should keep on hand for moisturizing your hair. If you do not own either of these tools for infusing moisture into your hair, you can create your homemade heating cap.

To Create Your Heating Cap:

Do this to create a heating cap:

Don a shower or conditioning cap.
Soak a towel that is large enough to wrap around your head in the water.
Heat the same towel in the microwave for about two minutes. You want this towel to be warm but not too hot. You don’t want to burn yourself.
Wring the towel of excess water. Wrap it around your head.
Warm the conditioner before application.

Tip: Warm your conditioner before application. This action supports efforts to open your hair cuticles.

What are the Best Products for Low Porosity Hair Care?

Humectants are one of the best products for low porosity hair. These products attract moisture from the air and stick to your hair. –Okay, it’s not a technical description, but you get it. This hair needs help, and humectants give a much-needed assist. Products that contain natural glycerin, honey, coconut nectar, or products with these ingredients may also serve as an asset. However, be careful in the winter months. During this time of year, humectants like glycerin may draw moisture away from your hair. Yikes!

Use Light Oils for Low Porosity Hair Care

Light oils like argan oil and olive oil are the best oils for your hair. Heavy oils and butter tend to leave build-up on natural hair with low porosity. Use the light oils sparingly, or avoid them entirely. A lighter oil can help ensure the molecules are small enough to enter the cuticle. You can hydrate the hair and seal in moisture.

Use Shampoo to Prevent Build-Up

Many naturalistas swear by the no-poo method for wash day. Don’t toss your shampoo just yet.

Here’s Why: Having hair with low porosity means your hair is prone to product build-up. It is difficult for products to fail to permeate your hair strands. Your low porosity hair routine should include sulfate-free shampoos like:

These are excellent products for hair with low porosity. These are known as clarifying shampoos and conditioners, which can help remove build-up without compromising the structure of your hair. Bentonite clay masks are another option for those seeking a more organic approach.

Hair Butter

Cupuacu butter and avocado butter are excellent moisturizers for low porosity hair. They are rich in antioxidants that fight free radicals that may damage your hair structure. They are lightweight, and thus, won’t weigh your hair down.

The Baggy Method

The baggy method is a simple moisturizing process that creates a humid environment for your low porosity hair using your body heat. All you need are a shower cap, conditioner cap, or plastic bag and a hat, towel, or scarf. To prepare your hair, moisturize it like you usually would. Cover it with a baggy, followed by a scarf or hat.

Some natural hair mavens will recommend you keep it on overnight. Others suggest that you not sleep in a cap. Rationale: It may cause more damage. Aim for a couple of hours at most. Ultimately, your goal is to achieve moisture-rich, soft hair.

Can You Use Protein Treatments on Low Porosity Hair?

Protein treatments and products containing protein are safe, they should be done sparingly. Rationale? Protein treatments can cause your hair cuticles to be more closed. The reason for this action is that protein products tend to build up the hair. Therefore, choose protein-free products. Protein-free moisturizers you can try out include:

In summary, the best way to care for low porosity hair is to adopt a consistent hair care routine. Your goal is to avoid product build-up, open the cuticles when moisturizing, and take a deep breath, and relax; You have GOOD HAIR.
