Invention to wash and dry hair

This man created this device after he saw his grandmother struggling when she had to wash her hair.

The grandson transformed an old helmet and a tank into a machine. The device uses a motorcycle helmet, two water tanks and a powered control panel, to heat water, wash massage and then dry the user's barnet.

First it sprays water and shampoo into the helmet, gently massages your scalp, thorough cleans hair and at the end blow-dries it with warm air. The device has settings for different temperatures that be customized for the user.

It took Chen 16 years and 18 broken helmets until he had this machine working.

Chen has successfully tested the device on his father and already received a national patent, and hopes his device will help millions of people who, like his gran, are unable or struggle to wash their own hair.
