This MP3 works with more than just Grey Hair, it develops thickness and texture changes as well. Many have reported that the color of their hair from 20 years came back, vivid reds and browns and blacks! Others that were dying their hair as often as weekly can now go for 8-12 weeks without a touch up!! Others have reported that new growth came in like gangbusters and their hair is thicker and fuller than ever before! Lynn covers mineral deficiencies; naturally occurring hydrogen peroxide in the body; shock, trauma, and stress; hair killing steroids; melanin, your hair pigment; and scalp hair growth stimulation – all using the consciousness and wisdom of YOUR body!
