What is the Anagen stage
Anagen is the active growing phase, a period of activity of the papilla and the germinal matrix. It is early on during this phase that the hair colour, thickness and shape are formed. Lasts on average
4-7 years, depending on age and individual, but can be as short as 1 year.
What is the catagen stage
the follicle is preparing to rest. The hair bulb gradually separates from the papilla and slowly moves further up the follicle. This stage lasts about two weeks.
What is the telogen stage
Telogen is the resting quiet phase, when there is no further growth or activity at the papilla.
This phase only lasts 3-4 months, during which time the follicle begins to shrink and separate from the papilla.
Towards the end of this phase cells begin to activate in preparation for the new anagen phase of re-growth to start the whole process again, repeating itself.
