The hair will feel coarse and dry,will be difficult to manage and will look
dull and frizzy. On the contrary, if your hair retains its natural moisture
content, it will be smooth, shiny and easy to style.
Hydra-sensor (A) and Hydra-indicator (B)
Thanks to the unique 'Hydraprotect' sensor system you can be sure that
the moisture content of your hair will be kept at its natural level.
During the drying process, the sensor continuously measures the humidity
of your hair and adjust consequently its air temperature. When the hair is
still very wet, the air temperature will be high enough to allow fast drying.
While the hair gets dryer, the air temperature decreases. When your hair
is almost dry and has a proper moisture content, the Hydraprotect dryer
will automatically select the caring temperature.
Note: when you start drying in wet hair , the Hydra indicator light will turn
green for approximately three seconds. This is the time the sensor needs
to adjust itself.
Make sure that the Hydra-sensor pins are in contact with the hair;
otherwise the sensor will not work. So, do not dry your hair from a
distance.
