Why our Hair turns White-
All our hair cells produce a tiny amount of hydrogen peroxide, which builds up over time as we age due to a reduction in catalase, tyrosinase, and MSR A and B.
Catalase is what breaks the hydrogen peroxide into water and oxygen.
MSR A and B are what normally repair the damage caused by the hydrogen peroxide in the follicle.
Together the high levels of hydrogen peroxide and low levels of the peroxide-damage-repairing MSR A and B, end up disrupting the formation of tyrosinase, which is a precursor to melanin production. Researchers think that this may also be what causes vitiligo as well!
