Hair porosity refers to how well your hair absorbs and retains moisture. There are three main levels of porosity: low, medium, and high . To determine your hair porosity, you can use the following methods: 1. The Float Test • Take a few strands of clean, dry hair (no product or oil on it). • Fill a glass or bowl with room-temperature water. • Drop the hair strands into the water and wait 2–4 minutes. • Low porosity: Hair floats on top, as the cuticles are tightly closed and resist absorbing water. • Medium porosity: Hair slowly sinks to the middle, as it absorbs a balanced amount of water. • High porosity: Hair quickly sinks to the bottom, as it absorbs water easily due to open or damaged cuticles. 2. The Slip Test • Run your fingers up a strand of hair from the tip to the root. • Low porosity: Hair feels smooth, indicating tightly closed cuticles. • Medium porosity: Hair feels slightly textured, indicating healthy cuticles. • High porosity:...
