    Glossary Hair Follicle Density

    number of hair follicles per unit area of skin

    Hair Follicle Density, also known as Follicular Density or Hair Density, refers to the number of hair follicles per unit area of the scalp or skin. It is typically measured in follicles per square centimeter. This metric is important for assessing hair health, diagnosing conditions like alopecia, and planning hair restoration treatments. Higher follicle density generally indicates thicker hair coverage, while lower density can be a sign of thinning hair or hair loss.
