Is also a form of diffuse hair loss like telogen effluvium, but develops much more rapidly and can cause a person to lose all their hair. The condition is most frequently caused when taking cytostatic drugs for cancer or associated with chemotherapy. Since chemotherapy targets your body’s rapidly dividing cancer cells, your other rapidly dividing cells such as hair follicles in the growing (anagen) phase, are also greatly affected. Soon after chemotherapy begins approximately 90 percent or more of the hairs can fall out while still in the anagen phase.
While the development of anagen effluvium is rapid, recovery can be equally as rapid. Because the follicles are just frozen in time they are ready to grow once the factor causing the anagen effluvium has been removed.
