The Science of Hair Porosity and How to Determine Your Hair Type

Hair porosity refers to the ability of your hair to absorb and retain moisture. Understanding your hair’s porosity level can help you choose the right products and treatments to maintain healthy, strong, and shiny hair. In this article, we will explore the science of hair porosity, and how to determine your hair type.

Hair Porosity Science

Hair porosity is determined by the structure of your hair cuticle, which is the outermost layer of the hair strand. The cuticle consists of overlapping scales that protect the inner layers of the hair. When the cuticle is tightly closed, the hair has low porosity and is less prone to damage, frizz, and breakage. On the other hand, when the cuticle is open, the hair has high porosity and is more susceptible to damage and moisture loss.

Factors that can affect hair porosity include genetics, hair type, chemical treatments, heat styling, and environmental factors such as humidity and sun exposure. These factors can alter the structure of the hair cuticle, making it more or less porous.

Low Porosity Hair

If you have low porosity hair, it means that the cuticles of your hair strands are tightly closed, making it difficult for moisture to penetrate. This can result in a build-up of products on the hair and scalp, as well as an accumulation of oils and sebum that can clog hair follicles and lead to hair loss.

To keep your low porosity hair healthy, it’s important to use lightweight, water-based products that won’t weigh down your hair or clog your pores. Look for products that are labeled as “light” or “water-based” and avoid heavy oils and butters that can sit on top of your hair and scalp.
