What Is Low Porosity Hair?

Low porosity hair refers to hair that has a tightly bound cuticle layer that makes it difficult for moisture to penetrate into the hair shaft. This type of hair is often characterized by hair that takes a long time to dry, resists chemical treatments such as coloring and relaxing, and is prone to product buildup.

The tightly bound cuticle layer of low porosity hair can be attributed to genetics, as well as external factors such as heat damage and chemical treatments. While low porosity hair can be a challenge to care for, it is important to note that it is not necessarily a bad thing. In fact, low porosity hair is often strong and resilient, and can hold styles well.

To care for low porosity hair, it is important to use products that are designed to penetrate the hair shaft, such as lightweight oils and leave-in conditioners. Heat is also an effective way to help open up the hair cuticle and allow moisture to penetrate, so using a hair steamer or sitting under a hooded dryer can be beneficial. Additionally, avoiding heavy products that can cause buildup, and minimizing the use of heat styling tools can also help maintain healthy low porosity hair.

How Do You Know If Your Hair Is Low Porosity?

There are several signs that can indicate if your hair is low porosity:

  1. Water beads up on your hair: When you wet your hair, the water tends to sit on top of the hair and take a long time to absorb. This is because the tightly bound cuticle layer of low porosity hair makes it difficult for water to penetrate the hair shaft.

  2. Hair takes a long time to dry: If your hair takes a long time to dry, even with the use of a hair dryer, it could be an indication of low porosity. This is because the tightly bound cuticle layer of low porosity hair makes it difficult for moisture to escape from the hair shaft.

  3. Products tend to sit on your hair: Low porosity hair is often prone to product buildup because the tightly bound cuticle layer makes it difficult for products to penetrate the hair shaft. If your hair tends to feel heavy or greasy, even after using a small amount of product, it could be an indication of low porosity.

  4. Hair resists chemical treatments: If you have difficulty achieving the desired results from chemical treatments such as hair coloring or relaxing, it could be an indication of low porosity. This is because the tightly bound cuticle layer of low porosity hair makes it difficult for chemicals to penetrate the hair shaft.

If you are still unsure if your hair is low porosity, a hair analysis test performed by a professional can provide more definitive results.

How to Care For Low Porosity Hair?

Caring for low porosity hair can be challenging, but there are several tips you can follow to keep your hair healthy:

  1. Use lightweight products: Heavy products can build up on low porosity hair, so it's best to use lightweight products that won't weigh down your hair. Look for products that contain ingredients such as glycerin and aloe vera, which can help to hydrate and nourish low porosity hair.

  2. Use heat: Applying heat to your hair can help to open up the cuticle layer and allow moisture to penetrate the hair shaft. Try using a hair steamer or sitting under a hooded dryer for 10-15 minutes after applying your deep conditioner.

  3. Clarify your hair regularly: Low porosity hair is prone to product buildup, so it's important to clarify your hair regularly to remove any excess product. Use a clarifying shampoo once a month to remove any buildup from your hair.

  4. Avoid using heavy oils: Heavy oils can weigh down low porosity hair, so it's best to avoid using oils such as coconut oil and castor oil. Instead, opt for lightweight oils such as argan oil or jojoba oil.

  5. Don't use too much protein: While protein is important for strengthening hair, using too much protein on low porosity hair can cause it to become stiff and brittle. Use protein treatments sparingly, and opt for products that contain hydrolyzed protein, which is easier for low porosity hair to absorb.

  6. Use a satin or silk scarf or pillowcase: Cotton pillowcases can cause friction and damage to low porosity hair, so it's best to use a satin or silk scarf or pillowcase to protect your hair while you sleep.

By following these tips, you can help to keep your low porosity hair healthy and nourished.
