Hair loss is a natural part of the body's process of renewal.
As some hair falls out, new growth replaces it. However, this process may be accelerated by a number of conditions. Hormonal changes may contribute to rapid hair loss, such as during pregnancy or childbirth, or even when coming off the Pill. As these fluctuations in hormone levels drop off, the hair loss should clear up, so the condition is only temporary. In a recent study, hormone levels were studied in both male and female patients experiencing severe hair loss.
