Chemotherapy and hair loss

Chemotherapy is a medication alternative for the treatment of cancer: it is the preferred treatment once cancer has extended aroundareas of the body. 

Among the cells that are attacked most by chemotherapy, are hair cells

Chemotherapy is today one of the causes of hair loss.

Chemotherapy consists of the administration of a medication (orally, intravenously or through the muscles), which has been designed to prevent cancerous cells from reproducing. However, these medicines do not have a selective design: they will act by attacking the cancerous cells as well as the other cells of the body.

How does chemotherapy treatment act on the hair?

Chemotherapy can interfere with the cycle of hair growth, more specifically with the phase of hair growth (the anagen phase).

The result is known as anagen effluvium: the hair follicles weaken in a way that they can no longer sustain the hair which they support and the hair falls. In addition to weakening the hair follicles, chemotherapy also prevents their reproduction, which is why the hair stops growing.

Hair loss normally occurs after a few days or weeks from the administration of the medication.
