A transitional, or catagen, stage.
Resting, or telogen, stage.
When new hair growth is initiated, the new anagen hair pushes the old telogen hair out, and shedding occurs. Typically a person sheds no more than 50 to 100 hairs per day.

Approximately 3 months after this stress, the new mother may experience excessive hair loss on the order of 100 or more hairs per day. This excessive hair loss is termed telogen effluvium. Up to 90% of postpartum women experience it. The condition can occur immediately after delivery but, more typically, it occurs between 2 and 6 months’ postpartum. The shedding rate returns to normal in 4 to 6 months.
