Many of us know that gray hair is due to lack of melanin, but nobody knows why melanin disappears all of a sudden, that is until now.

Scientists have recently discovered that there are four enzymes working together to cause hair to turn gray.

New discovery about the cause of gray hair was reported by the scientists and researchers at the the Universities of Bradford, Mainz and Luebeck. Details about their findings will be published in the Federation of American Societies for Experimental Biology's journal.

It was discovered that the primary or leading cause of gray hair starts with a reduction in the enzyme called catalase. Lack of catalase can result in an accumulation of hydrogen peroxide, hydrogen peroxide can in turn inhibits the production of the enzyme tyrosinase. Tyrosinase produces melanin, the hair's natural pigment.

Catalase enzymes in the body are known for their efficiency. They can break down millions of hydrogen peroxide molecules per second.

Excess hydrogen peroxide levels in the body do not only lead to graying hair. Hydrogen peroxide can also cause cell damage.

There is also a reduction of repair enzymes A and B preventing hair follicles from repairing the damage caused by the build up of hydrogen peroxide.

Research is underway to find out more about the mechanisms that lead to gray hair and possible treatment, according to one of the researchers, Karin Schallreuter, a professor of clinical and experimental dermatology at England's University of Bradford.

For those who can't wait for scientists to come up with a new product that target the lack of catalase, you may want to consider supplements that can boost catalase in our body. However, there is presently no research that suggest catalase boosting supplements can indeed reverse gray hair. Catalase is one of 4 naturally produced free-radical fighters that protect against cell damage. Catalase, along with the other 3 - superoxide dimutase, methionine reductase, and glutothione peroxidase- are all available in supplement form.
