How to Test Your Hair Porosity at Home

In this short tutorial, Jen Booth explains that hair problems often stem from the hair's porosity—the ability of strands to absorb and retain water. She demonstrates a quick at‑home test: place a clean hair strand in a clear cup of water and observe its behavior. If the strand floats, the hair is low porosity; if it slowly sinks, it is medium porosity; if it drops quickly, it is high porosity. Jen describes how each porosity type affects moisture retention and product performance—low porosity resists moisture and can feel heavy with product, while high porosity absorbs quickly but also loses moisture fast. Understanding one’s porosity enables the selection of appropriate products and techniques, leading to more consistent hair results. She concludes by inviting viewers to seek personalized hair‑care plans based on their porosity.
