I admit it, I'm a fan of air drying. I have a somewhat problematic scalp, which I would like as little as possible to expose the stress caused by the heat of Fönens, but sometimes it's just unavoidable.
And because I have done with a really good disem Philips hairdryer handle. In the ThermoProtect stage neither hair nor scalp feels strained at which drying is pretty fast and the hair looks good.
Of course, there are other levels of heat very cold to very hot, but I do not want to miss the ThermoProtect stage. As an accessory, a concentrator and a diffuser here who have done both before me well.
The cable could be a little longer for more freedom of movement and of the so-called Ionisierungseffekt I do not think much, but otherwise I am very satisfied with the device.
