Hair loss is often described as if the follicle simply “stops growing.”
The biology is more nuanced. In androgenetic alopecia, the changes happen gradually, across repeated hair-growth cycles. Understanding what is happening at the follicular level helps explain why AGA is a progressive condition and why the biology behind hair loss matters when studying potential treatments.
This serves as the basis for grasping the follicle and pursuing further research into answers.
