Grey hair

Having a good head of hair is generally associated with youth and health. So when do we start to turn grey? The explanation is straightforward and is genetically determined. It is caused by reduced enzyme activity which inhibits the formation of pigments. Because we are now able to identify this gene, we can help by replacing the enzymes that have been lost due to the limited activity of the gene. We are talking about very simple plant structures which are supplemented by amino acids and L-glutamine. So for people who have turned grey prematurely, there is every chance that some of their hair will revert to its previous color.
