Hair is the second-fastest-growing tissue in the human body, after bone marrow. On average, it grows between 0.5 and 1.7 cm per month, but the rate can vary depending on genetics, age, and gender, male hair tends to grow faster than female hair. Hair grows fastest between the ages of 15 and 30, after which the growth rate slows down. As people age, some follicles stop functioning altogether, which can lead to thinning hair or baldness. Several factors influence hair growth, including hormones, overall health, and lifestyle choices. Proper nutrition, including a balanced intake of vitamins and minerals, is essential for maintaining strong and healthy hair. Staying hydrated and managing stress levels can also contribute to better hair health and growth.
