Are you pulling your hair back? Tension on the roots can cause hair to come out from the roots. Also are you under any stress? Stress can be a big culprit in hair loss. Another thing is sleeping on one side with cotton pillows. Cotton not only dries your hair out but it pulls the hair out from rubbing. Get a silk pillow cover or sleep in a silk scarf. I don't see why your hair would fall out naturally if you are not using any harsh chems so I am suspecting something I mentioned above.
