Understanding Hair Porosity

Porosity is how well hair absorbs moisture. Low porosity has tight cuticles. Medium is balanced. High porosity absorbs fast but loses moisture fast. Always do a strand test before full application. Deep condition weekly to keep hair healthy. Use heat protectant before any hot tool. Trim split ends every eight to twelve weeks. Rinse with cool water for extra shine. Avoid washing hair with very hot water. Protect hair from sun with hats or UV sprays. Sleep on a satin pillowcase to reduce breakage.

The Float Test Explained

Drop a clean strand in water. Floating suggests low porosity. Sinking suggests high porosity. It is a rough guide, not a diagnosis. Combine with how hair behaves. Always do a strand test before full application. Deep condition weekly to keep hair healthy. Use heat protectant before any hot tool. Trim split ends every eight to twelve weeks. Rinse with cool water for extra shine. Avoid washing hair with very hot water. Protect hair from sun with hats or UV sprays.
