Caffeinated Drinks and Hair Loss(Coffee,Green Tea,Soda)

[cs2257]

So a little background...

For the last year I've been noticing a strong itch within several minutes of having Coffee, Green Tea, or any Caffeinated Soda.
When I rub or scratch the itch, hairs fall out in that region.
The same beverages also put me on edge to a degree. Why would it causes the itch/hairloss?

When I cut out soda/caffienated beverages, the itch is gone/I shed less.

Does this indicate anything? Has anyone else had the same experience?
