Hair growth is a natural process where new hair strands form in hair follicles located in the skin. Each hair follicle goes through a cycle that includes growth, rest, and shedding phases. The average person loses about 50 to 100 hairs daily, but this is usually replaced by new growth. Several factors influence hair growth, including genetics, age, and overall health. Nutrients like vitamins A, C, and E, as well as minerals like zinc and iron, play a crucial role in maintaining healthy hair. Hormones also affect hair growth, with changes often seen during puberty, pregnancy, or menopause.
