Glossary Anagen Hair Ratio

proportion of hair follicles in the active growth phase

The Anagen Hair Ratio refers to the proportion of hair follicles that are in the anagen phase, which is the active growth phase of the hair cycle. A higher anagen hair ratio indicates a greater number of hair follicles are actively growing, which is typically a sign of healthy hair growth. This ratio is often used by dermatologists and trichologists to assess hair health and diagnose conditions like alopecia.
