A hairbrush that helps you rate a 'bad hair day'!
A new Japanese hairbrush may soon be
able to help hairdressers work out the appropriate treatment for a person in
their care, as it will be able to quantify the damage caused by treatments such
as hair dyes and bleaches.
Thanks to Japan's Kao Corporation it would soon be possible to rate a ‘bad hair
day’ on a scale of 1 to 10.
The hairbrush would be able to analyse the sound while hair is brushed revealing
the state of the hair, according to five inventors from the company.
The brush contains an aluminium bar, which is polished, sandblasted and then
buried amongst its prongs. A microphone is attached to the bar that picks up
vibrations as hair is dragged over the bar. A built-in strain gauge also records
the resistance caused by brushing, reports New Scientist.
A USB connection then feeds these measurements to a PC which compares the sound
and the pulling strain.
Tests carried out in a Tokyo hair salon showed that hair in good condition makes
far less noise than dirty hair with split ends.
Loud sound at high frequencies also indicates too much bleaching, the inventors
said.
