how long does hair take to grow

Hair typically grows at an average rate of about half an inch (1.27 centimeters) per month, which translates to roughly 6 inches (15 centimeters) per year. This rate can vary based on factors such as age, genetics, health, and hair care practices. Hair growth occurs in phases, with the active growth phase (anagen) lasting 2 to 8 years, during which hair continuously grows before shedding and being replaced. On average, people lose about 100 hairs each day as part of the natural cycle.
