There are different types of diffusers. Diffusers typically work best when the blow dryer is set to low heat and low-speed settings. Use a slow circular motion, which will help prevent tangling and unnecessary frizz.
Applying oil or other treatment product before or during the diffusion process will help protect the hair more than applying it afterward.
