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!
2c/3a?

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