Hair growth is a natural process where new hair strands emerge from hair follicles in the skin. Each hair grows in cycles, which include a growth phase, a resting phase, and a shedding phase. Factors like genetics, age, and health can influence how quickly and thickly hair grows. The average person loses about 50 to 100 hairs daily, but this is normal. To promote healthy hair growth, it's important to maintain a balanced diet rich in vitamins and minerals, such as biotin and zinc. Additionally, proper hair care practices can help prevent damage and support overall hair health.
