  • What is the difference between a professional hair dryer motor and a traditional motor?

    A professional motor ensures better performance and has a longer lifespan than a traditional motor.

    A traditional motor has a lifespan of up to 500 hours of use. Its performance is limited to drying or simple styling of your hair with a maximum air flow of 95km/h and concentrator nozzles of 9, 10 or 14 mm. You will find these motors in the Expert line.

    The professional AC motor increases the lifespan of your hair dryer to up to 2000 hours. In addition to blow drying, it lets you create technical and professional hair styles. Thanks to its powerful air flow (up to 170km/h) and slim concentrator nozzles (6 or 4 mm), you get a long-lasting result. These motors can be found in our Pro line.

    Finally, the latest-generation digital professional motor is revolutionary. Its exceptional performance (10,000 hours of use and 208 km/h air flow) allows the temperature to remain a constant low 70°C, which is the ideal temperature to respect the cuticle and the hair’s natural moisture. It has a 30% faster drying time. 6000E and 6100E models are equipped with this revolutionary motor.

  • How many watts should a hair dryer have?

    Let’s put this preconception to rest!
    Watts determine the appliance’s air flow temperature and energy consumption. So it is essential to refer to the speed of the air flow in km/h rather than to the watts, since a higher speed means a faster drying time.

  • What is the ionic function on a hair dryer? What is it used for?

    The ions generated by the hair dryer neutralise the static electricity that sometimes occurs in hair when dried. And the effectiveness of leave-in haircare products is reinforced: hair is smoother, softer and glossier.

  • What is the concentrator nozzle used for? What is the difference between 4, 6 and 10 mm?

    The concentrator nozzle is used for a precise styling, such as a blow dry or a finishing of the tips. The slimmer it is, the more precise the styling will be. It is ideal when used on low speed (+ turbo if available) and a low temperature setting.
    The large concentrator nozzle lets you smooth the hair fibre efficiently. It is ideal when used on high speed (+ turbo if available) and a low temperature.

  • How do I use the hair dryer diffuser?

    To maintain natural curls and waves, we recommend using the diffuser. Use a low speed and high temperature to bring out your curls.
