Follicular Anagen Phase

Meaning

The Follicular Anagen Phase is the critical, active growth stage of the hair cycle, characterized by a period of rapid cell proliferation and differentiation within the hair follicle matrix. This is typically the longest phase of the hair cycle, during which the hair fiber is actively synthesized and pushed outward from the scalp. The health, duration, and robustness of this phase are significantly influenced by systemic hormonal status, adequate nutrient availability, and underlying genetic predispositions, directly determining overall hair density and length.
