Generally, people shed from 50 to 100 single hairs per day! Hair shedding is part of a natural balance where some hairs fall out while others grow to take it’s place.
When the balance is distrupted, hair loss happens.
Hair goes through three cycles:
The anagen phase (growing phase) can last from two years to eight years.
This phase generally refers to about 85% to 90% of the hair on your head.
The catagen phase (transition phase) is the time that hair follicles shrink and takes about two to three weeks.
The telogen phase (resting phase) takes about two to four months. At the end of this phase, the hair falls out.
