High Porosity vs. Low Porosity

Posted by Kalen Spate on

Is your hair not retaining moisture? Are you tired of dealing with frizzy, tangled, and DRY hair every day? Finding out your hair porosity could be just the solution to your hair struggles.

Hair porosity refers to how well your hair can absorb and retain moisture. Your hair's porosity could be genetic or simply the effect of everyday environmental factors such as manipulation and weather. There are 2 different categories for hair porosity:


Low Porosity Hair- low porosity hair has a tightly bound cuticle layer. This porosity level is usually healthy but tends to repel moisture. Low porosity hair has a very hard time retaining moisture because it has an even harder time receiving moisture. The best way to moisturize low porosity hair is by adding heat when applying any moisturizers such as water, deep conditioners, and even leave-in conditioners. 


High Porosity Hair- high porosity hair has lifted cuticle layers. This porosity level can be a direct effect of damaged hair or simply inherent. One thing for sure, high porosity hair easily accepts moisture, but it can just as quickly lose that moisture because of the raised cuticles along the hair shaft. High porosity hair is usually frizzy, lack-luster, and can even have gaps and holes along the hair shaft. The best way to moisturize high porosity hair is to follow up using sealants such as oils and butter to help trap in the moisture. Incorporating anti-humectants into your hair regimen can also help fight against dry frizzy strands. 


Do you want to determine which hair porosity you have?

The Float Test: Just take a couple of strands of hair from your comb or brush and drop them into a clear glass of room temperature water. Let them sit for 2-4 minutes. If your hair floats, you have low porosity. If it sinks, you have high porosity.
