Dear Ouidad: When you have naturally curly hair, is it best if you use a diffuser? Or a product in conjunction with a diffuser?

A: First, curls are better if they are left to air dry, and products will help set them in place. However, many of us need to have our hair dry before we leave the house. So you can use a diffuser, but use low heat and use products such as Climate Control that will help protect the hair from heat and help hold the style.
