rate at which hair length increases over time
Hair Growth Rate refers to the speed at which hair grows, typically measured in millimeters or inches per month. On average, human hair grows about 0.5 inches (1.25 cm) per month, though this can vary based on factors like genetics, age, health, and nutrition. Understanding this rate is crucial for professionals dealing with hair loss treatments, hair care products, and clinical studies related to hair growth and alopecia.
