Provillus Reviews:Anagen effluvium happens when the hair follicle cells are so damaged they can not recover or reproduce. This is usually due to toxicity of chemotherapy for cancer. Chemotherapy is meant to destroy rapidly dividing cancer cells. Hair follicles in the growing (anagen) phase, are therefore vulnerable. Anagen effluvium means the hair shaft narrows as a result of damage to the follicle. The shaft breaks off at the narrowing and causes the loss of hair. https://goldencondor.org/provillus-reviews
