Part of that story sounds suspect. Hair is dead, besides the root/follicle. How could you remove nutrients from your scalp by doing anything to the end of your hair? I wonder if the reporter didn't catch on and he actually had his head hanging in the water (so the water was touching his scalp). Also the "even blasts it with UV light" isn't actually that weird. We have a well and we treat the well water with a UV light disinfector. What's stranger is why you'd need to worry about bacteria growing in ultra-pure water. What would the bacteria eat?
