No important – but what the hey! Practically confirmed on my cleaner.
Run a 8 W 1 MHz ultrasonic massage device over the scalp. Take time over the crown. It is not instant – my cleaner has had 15 goes, and while he is no longer bald, he just looks 112 years yuonger.
At the same time I am using it to trmoe his wrinkles – which is what the devices are sold for.On a more serious note, it clears mental health problems and the migranes he used to have.
