I use many years the ion brush from Braun for my long, dyed hair. It smoothes the hair quickly and makes it look shiny. Since I have had good experiences with the brush, I wanted to try the Ionic Hair Dryer. The Ionenföhn Grundig has three temperature, two fan and a cold setting. As with my other hair I set the temperature as the fan regulator to medium. It took a little here, to the hair dryer was warm. After using the hair was silky soft and shining beautifully. A clear advantage. However, when I tried - what I always do - the hair for more volume from the bottom to blow at the base, they were immediately drawn to the peaks from behind, because the device does not have an outer protective grid at the end such as my of more expensive hairdryer from Braun , This hair dryer is therefore not suitable for very long hair and for this kind of blow-drying. Apart from that, I find that he is not very high quality compared to some other brand appliances. For slightly greasy hair ion brush and especially Ionenfön way, are not so good because they stimulate the production of sebum. I will use this hairdryer from time to time for a change, if I did not have so much time for combing and styling, because it saves a little smoothing. Those interested in an inexpensive Ionic Hair Dryer and can live with my subjective criticisms, can try this with a clear conscience, because at this price it is a bargain.
