I diffused for about a week after buying an ion ceramic dryer with diffuser but I'm back to air drying. If I need to go somewhere I'll disffuse on warm but 99% of the time I air dry.
My curls need time to wind around and they can do that better air drying and I don't have to sweat that way. Diffusing raises my body temp whew!
Low porosity, medium texture.

If it smells good put it in your hair, if it tastes good spit it out!
