    Glossary Anagen/Telogen Ratio

    measure of hair follicles in growth vs. resting phases

    The Anagen/Telogen Ratio is a measure used to assess hair growth and health by comparing the number of hair follicles in the anagen (growth) phase to those in the telogen (resting) phase. A higher ratio indicates a greater proportion of actively growing hair, which is typically a sign of healthy hair growth, while a lower ratio may suggest hair loss or a disruption in the hair growth cycle.
