    GlossaryProliferation Index

    measure of cell division rate in a given tissue

    The Proliferation Index is a measure used to determine the rate at which cells are dividing and multiplying. In the context of hair and alopecia, it can help assess the growth activity of hair follicle cells, providing insights into hair health and potential treatments for hair loss. For professionals, it is often quantified using markers like Ki-67 in tissue samples to evaluate cellular activity.
