You, my dear, are missing some vitamins. Nexxus has a product pack for that problem. Sometimes your shampoo will do that and hard water doesn't help. As a stylist for 28 years I found a lot of people that use hairspray everyday have that problem. If the hair pieces that fall are small it is breakage. Need a trim and a rinse of vinegar and water to clean and balance your hair.
The average hair loss per day per person is about 100. I loose a lot of hair daily too. I have to vacuum it off the bathroom floor daily!! (well, I should) And I'm not thinning either. I'm 55 and it's been like this my entire life.
Also loosing of hair can be because of stress and depression
Go to sally's hair & beauty store, there's some really good salon shampoos/conditioners in there at affordable prices, one I'd recommend is Schwartzcroft Bonnacure damage repair. You'll also will need a trim as expressed by the first replier.
