In an anagen effluvium type of hair loss, the hair follicles have their hair fiber growth actively blocked. Anagen effluvium develops in a very short space of time. People on intensive chemotherapy may lose all their hair in a few days. Anagen effluvium is not a permanent form of alopecia. Once the chemotherapy is stopped the hair follicles rapidly reorganize themselves and start growing hair again.
New hair can be visible within four weeks of completing chemotherapy.
A full head of hair may take a few months. Contact organization addresses American Cancer Society 1599 Clifton Rd.
