Diffusers fit on to the nozzle of the dryer to give a gentler heat without the blow. This way of drying is especially effective on permed or naturally curly hair. The low air-flow is also good for fine, flyaway hair. The best diffusers have 'lifters' or 'prongs' which separate and ruffle the hair as it dries.
Diffuser - This big, round attachment is designed specifically for curly hair. The flow of air is dispersed so that curls aren't straightened by the heat force. Use with the diffuser attachment of your hairdryer, for relaxed just-got-out-of-bed curls. Finish with a hair wax designed for the tousled look.
Professional tip for Diffuser
To create a structured look on short hair, towel dry hair and apply gel, then style hair using a comb and fingers then hold the diffuser still, drying a section at a time. For a casual naturally-curly effect on long hair, you should towel dry hair and apply mousse. Place sections of hair into the dish of the diffuser as it dries. To finish, take the curls gently with the fingers.
Infra-dryers
Infra-dryers are relatively new concepts that intensify the benefits of diffuser drying. The combination of diffuser and infra-red lamp dries the hair with gentle heat rays rather than hot air. They are perfect for naturally curly, permed or short, structured cuts. This method of drying gives an even result without over- drying the ends.
