Hair loss, occurs because anticancer drugs can affect normal cells, including the cells responsible for hair growth. This effect, however, is not permanent, and healthy cells grow back normally once chemotherapy is completed.
Scalp hairs in the, "anagen" or growing phase (about 90%) is susceptible to chemotherapy and radiation. The degree of hair loss depends on the chemotherapy drug, the dosage of chemotherapy or radiation, and how it is given.

In Chemotherapy hair loss, starts approximately 2-3 weeks after your first dose of chemotherapy, but won't be total until 1-2 months have elapsed. Hair loss is reversible and will be back totally about 3-4 months after the last chemotherapy dose. Your hair may even grow while you're on chemotherapy. This doesn't mean that the chemotherapy isn't working. Unfortunately, some of this regrown hair may also fall out. Hair on the head is most commonly affected, but hair loss may also occur on the face, arms, legs, underarms, and pubic area.

In Radiation only hair that is in a treatment field will be affected with hair loss. Generally, the hair loss will begin approximately 2-3 weeks after the start of treatments. This hair will grow back after the treatments are completed. If a higher dose of radiation is delivered, there is a chance that the hair loss will be permanent. Check with your Radiation Oncologist if you have questions and concerns about this.
