There are many hair changes attributable to anticancer therapies. In approximately 65% of patients treated with chemotherapy and in up to 100% of areas treated with radiotherapy can lead to hair changes.
These can manifest as hair loss (alopecia), pigment changes, textural changes, and changes in hair cycle.
Hair Loss
Chemotherapy induced hair loss typically begins weeks after the first dose of chemotherapy and represents what is called an anagen effluvium, predominantly in areas of increased friction on the scalp. Eyebrows and eyelashes may also be affected. Usually asymptomatic, it can be associated with itch or pain. Two to six months after the chemotherapy has finished, the hair typically begins to regrow, although the hair loss can be persistent.
