The anagen phase hair growth stage is the active growth phase of the hair growth cycle, where hair follicles continuously produce new hair. It is part of the full anagen catagen telogen cycle and plays a crucial role in determining hair length and thickness.
Hair Growth Cycle Explained
The hair growth cycle consists of three main stages:
- Anagen (growth phase)
- Catagen (transition phase)
- Telogen (resting phase)
The anagen phase is the longest and most important stage for visible hair growth.
Anagen Phase Duration
The anagen phase duration typically lasts between 2 to 7 years, depending on genetics and individual factors.
Hair Growth Rate
During this phase, hair grows approximately 1–1.5 cm per month.
Hair Transplant Growth Phase
After a transplant, follicles eventually re-enter the hair transplant growth phase, which corresponds to the anagen stage.
