Diffusers disperse the air from the hair-dryer, preventing the dryer from roughening up the cuticle of the hair. It protects curls from frizz and also adds volume to fine hair. 

PLEASE NOTE: This silicone diffuser can stretch around a 5-6cm hair-dryer mouth. Never diffuse on a high heat dryer setting. Toggle between the cool/medium settings. 

*THE CURRENT BATCH OF BLACK DIFFUSERS ARE WITHOUT MARLEY GREY LOGOS*
