chaz no disrespect here but "gong" --- grey hair is caused by acidic sulfers destroying the gas chimminies of your body called the hair shaft. These shafts in the perfect body are there to exsude a natural perfume created by your body to show your health and beauty. As we eat acid wich is what your describing and drink the same and many other substances the shafts "burn" from the acid but first turn grey then fall out. DO NOT TAKE INTO YOUR BODY ANY ACIDS
