Hair Growth Rate: How Much Does Hair Grow Per Week?

On average, hair grows about 0.5 to 1.7 centimeters (or 0.2 to 0.7 inches) per month. That translates to approximately 0.125 to 0.425 cm per week.

Keep in mind that this is just an average, and individual hair growth rates can vary greatly depending on genetics, age, diet, health, and other factors.
