GlossaryGrowth Rate

speed at which hair grows over a specific period

Growth Rate, also known as Growth Velocity, refers to the speed at which hair grows over a specific period of time. Typically measured in millimeters or inches per month, this rate can vary based on factors such as genetics, age, health, and hormonal influences. Understanding growth rate is crucial for both diagnosing hair disorders and planning treatments in trichology and dermatology.
