Head shower   (+5)  [vote for, against]
Permant hirsute cleanliness

Showering one's head is very soothing and stimulating for the brain, as well as cleaning dirt from the hair.

This device consists of a hermetically sealed hat which encloses the top and back of the head. A shower nozzle is fitted inside so as to spray water evenly but powerfully onto the head and hair. The water drains to the back of the neck and is extracted, filtered and recirculated via a backpack-mounted device.

A bluetooth interface allows real-time or pre-set control of the wash cycle and temperature.

Available in co-ordinating colours so you can go about your daily business while wearing it.

Needs optional earflaps to drown out (heh) ambient noise, similar to those hair dryer stands once found in Aunty Liz's beauty shop. Bonus ear cleaning included, I suppose.

This invention may soothe a certain type of autistic. There may also be applications in the mental health field, for folks with anxiety disorders, or psychological injuries like PTSD.

Hey, you could save a bundle on segregation cells to calm violent offenders in jails: simply build a single "salon" full of these helmets, with space to stroll around, and some comfy chairs with a dip in the back to accommodate the head unit. (I'm sure La-Z-Boy will see the cross-marketing potential.)

I wash I had thought of this.

Some would fill the device up with beer or wine, so sales should not be a problem near colleges with fraternities, and in certain religious sects. I fear a vodka filled machine would be lethal.

My favourite bit of the paper linked by [Voice] is the sub-heading that reads "Ethanol as a penetration enhancer".

Don't be afraid ... you'll wonder why you ever hesitated...
