Hair does not fall out. This hair is known as club hair. This stage lasts for 2 to 3 weeks. About 1% of hair on scalp is in resting or catagen phase. Then hair move towards last phase of its life cycle.

Telogen Phase
Telogen (Fallout Phase)

Telogen (Falling Phase)

In this phase the club hair which get detached from blood supply get thinner and weaker and fall out at last. This phase lasts for 3 months. At any time around 10% of hair are in the falling phase.
