Gokhan,

Is there a history of early hair whitening in your family? It tends to be
genetic. Also, you might try the yoga pose shoulderstand. It is one of the
best poses for bringing circulation back to the head and above the heart. It is
a regenerative exercise. The yogic scriptures say that 15 minutes of
shoulderstand is equal to 2 hour of sleep.

> Although I'm 25 years old my hair started graying day by day. I
don't know what I have to do.
