Understanding your hair porosity is the ultimate secret to unlocking healthy, thriving curls and coils. For many naturals, the frustration of dry hair or product buildup comes down to one simple thing: using the wrong products for their specific porosity type.
At Saru Organics, we believe that education is the first step towards a successful hair care journey. Here is everything you need to know about hair porosity and how to choose the right plant-powered products for your unique texture.
What is Hair Porosity?
Hair porosity refers to your hair's ability to absorb and retain moisture. Your hair strands are covered by a protective outer layer called the cuticle, which consists of tiny, overlapping scales. How tightly these scales sit together determines your porosity type.
Porosity is generally split into three categories: low, medium, and high. It is largely genetic, but chemical processing, heat styling, and environmental damage can also alter it.
The Three Types of Hair Porosity
1. Low Porosity: The Moisture Blocker
In low porosity hair, the cuticle scales are tightly bound and overlap like shingles on a roof.
- The Struggle: It is highly resistant to letting water and moisture in. Products often sit on top of the hair, leading to fast buildup.
- The Signs: Water takes a long time to saturate your strands when washing, and your hair takes a very long time to air dry.
2. Medium Porosity: The Perfect Balance
Medium (or normal) porosity hair has cuticles that are perfectly aligned but loosely woven.
- The Benefit: It easily absorbs moisture and holds onto it for a reasonable amount of time.
- The Signs: It is low-maintenance, holds styles well, and requires minimal effort to stay hydrated.
3. High Porosity: The Moisture Escape Artist
High porosity hair has gaps, holes, or raised cuticles along the shaft.
- The Struggle: While it absorbs water and products instantly, it loses that moisture just as quickly because the cuticle doors are wide open.
- The Signs: Hair dries almost instantly after washing, is prone to frizz and breakage, and often feels dry shortly after moisturizing.
The Floating Hair Test
Not sure what your porosity is? Try this simple test at home:
- Wash your hair thoroughly to remove all product buildup.
- Pluck a clean, dry strand of hair.
- Drop it into a glass of room-temperature water and wait 2 to 5 minutes.
- The Result: If it floats at the top, you have low porosity. If it floats in the middle, you have medium porosity. If it sinks to the bottom, you have high porosity.
