Hair Growth and Follicle Health: Why Early Stages Matter Most
The scalp contains up to one hundred thousand hair follicles, all present from birth. Hair grows in a repeating cycle that includes a growth phase, a brief transition, and a resting phase that ends with shedding.
In early hair loss, this cycle becomes disrupted. More follicles enter the resting phase prematurely, while fewer return to active growth. Blood flow to the scalp decreases, nutrient delivery weakens, and growth signals become less effective, often before obvious baldness appears.
This is the stage where clinical intervention is most effective.
