Why take both?

Your curl type tells you roughly how your hair behaves and gives you a starting product weight: waves want light products, curls want moisture and hold, and coils want layered moisture. Porosity fine-tunes that, because it decides how easily water and products get into each strand. Together they explain why a product that works for a friend with the "same" curls can feel heavy or useless on you.
