What Is Hair Porosity? Understanding High and Low Porosity Hair
Many people searching for hair porosity, low porosity hair care, high porosity hair care, and moisture retention for healthy hair are looking for simple ways to choose products that match their hair's unique needs.
Healthy hair starts at the scalp.
One of the most misunderstood topics in hair care is hair porosity. Many people hear terms like "high porosity" and "low porosity" but are unsure what they actually mean or how they affect their hair care routine.
Understanding your hair's ability to absorb and retain moisture can help you choose products that better support healthy, manageable hair. In this article, Certified Trichologist Sayblee Darsale explains hair porosity in simple terms and why it matters for long-term hair wellness.
I have heard many hairstylists, salon owners and influencers talk about hair porosity, but knowing the science of hair, some of the things I hear make me shake my head. I’d like to simplify for you what porosity means and why your hair porosity is an important consideration when you choose hair care products.
What Is Hair Porosity?
Hair porosity refers to the ability of the hair to take in water and hold it. What is the difference between high and low porosity hair? If the hair is easy to get wet and hard to get dry, you have highly porous hair. If the hair is hard to get wet and easy to get dry, you have low porosity hair.
High Porosity vs. Low Porosity Hair
You want your hair to be moderately porous because that will allow it to retain moisture without retaining excessive amounts of water or grabbing on to chemicals or color too quickly.
Common Challenges of Low Porosity Hair
If the hair has low porosity, it takes a long time to absorb moisture or natural oils. Products just sit on the surface without being absorbed, which leads to build up, and the hair will lack volume and elasticity. Products with chemicals are the number one reason for the hair to have low porosity.
Be mindful of the products you use. To help achieve a balanced healthy level of porosity, select products that do not have ingredients with sulfates, petrochemicals and silicones.
How to Identify Your Hair Porosity
While professional assessment is the most reliable method, some common signs include:
High Porosity Hair
- Absorbs water quickly
- Dries slowly
- May feel dry despite frequent moisturizing
- Can be prone to frizz
Low Porosity Hair
- Takes longer to become fully wet
- Products may sit on the surface
- May experience product buildup
- Can feel resistant to moisture
Why Hair Porosity Matters When Choosing Hair Products
Understanding your hair porosity can help you choose products that better match your hair's needs.
Hair that struggles to retain moisture may benefit from nourishing products that support hydration, while hair prone to buildup may benefit from lightweight formulations designed to maintain scalp and hair balance.
