WebAug 21, 2024 · THE H20 TEST: To determine your hair porosity level using water, spritz a small section of curls with water and watch how your hair reacts – does your hair absorb the water quickly (indicating high porosity) or does it remain on top (indicating a low porosity level)? Now that you know what your hair porosity is let’s move onto the fun stuff. WebNov 23, 2024 · 1. Low Porosity. Low porosity hair cuticles are tightly closed and resist moisture absorption into the hair shafts. This hair type takes time to absorb moisture, making it prone to buildup and excess oil accumulation on the scalp. Low porosity hair can lock in moisture for a long time and looks healthy and shiny. conair 225r hair dryer
