Hair loss occurs when more hairs fall out than grow. The condition affects 70% of men and 40% of women, with the most common type being genetic hair loss, known as Alopecia Androgenetica.
Hair loss refers to the thinning or loss of hair, typically from the scalp, but it can also affect other parts of the body. Baldness results when hair falls out faster than new hair can grow. Hair loss is a natural process; in healthy individuals, a hair can remain in the scalp for three to five years, during which it grows. After this, the hair falls out and the follicle enters a resting phase for about three months before producing a new hair. With 100,000 to 150,000 hair follicles on your scalp, losing 50 to 100 hairs per day is normal. However, excessive hair loss occurs when many more hairs fall out without being replaced, leading to baldness or alopecia.
