Step Into My Shoes – Hair Gone Crazy!

SCENARIO: My hair gets greasy after three days, but it never did this before.  I used to be able to go five days without washing it!  Do you think it might be too warm in my room during the winter?  My hair is very long, so I’m scared to wash it too often for fear it will get damaged or I will experience hair loss (it has happened to me twice in the past).  Do you think I need to get a better shampoo, maybe something from Redken?  Help!
