I had trouble mid-30's with suddenly-my-hair-falling-out-like-crazy.... it was crazy!!! and eventually was determined to be a severe protein deficit in my diet (I was losing weight and strength training and NOT watching my protein intake, which turned out to be extremely extremely way too low - improved my protein intake and voila, no more excessive hair loss and it all came back in just fine).
A co-worker (mid 40's) had trouble with extreme thinning hair that could not be resolved. She ended up getting a wig. You can't tell she's wearing a wig, and her hair always looks FABULOUS.
