Does working more result in hair loss?

Hello folks,

Here is story of Ramu, who is industrious by birth. Hardwork is his only mantra and the Obsession of his life.
For him all that matters is the amount of time he spends with books in his hand or the computer infront of him.

And naturally he is a constant thinker and always worried about something or the other. There is no single moment when his brain is actually at rest. In other words he and his brain are idlophibic (Fear of being idle).

Now the question is people say when you use any part of your body, there is constant blood flow to it, and hence healthy functioning of that body. Now logically speaking, his head and the brain should be dead strong.
And so should be anything that grows over, underneath or inside the killer organ.

But to everyones wonder, and to his own wonder (his hair is literally fed with coconut oil) , he is the uncle in his office with already three fourth of his farm gone in the wind....

The Question is Did Ramu loose his hair because of Over work and Overstressing his head??
