On average, hair growth usually occurs at a rate of about 1 centimeter each month from hair follicles located under your skin. The single scalp hair usually goes through alternating growth and rest phases every 2-4 years before falling out and allowing new healthy hair to grow. This cycle repeats and it is normal for you to lose scalp hair everyday.
