sudden hair loss during the growth phase, often from chemotherapy
Anagen Effluvium is a type of hair loss that occurs during the anagen phase, or growth phase, of the hair cycle. It is often caused by factors that disrupt the rapidly dividing cells in hair follicles, such as chemotherapy, radiation therapy, or exposure to toxic chemicals. This condition leads to sudden and widespread hair shedding, primarily affecting the scalp but potentially other body hair as well.
