Chemotherapy drugs are very powerful medications that attack rapidly growing cancer cells. Sadly, these drugs also attack other rapidly growing cells in your body – including those in your hair roots.
Not just on your scalp, but the therapy may cause hair loss all over your body. Sometimes your eyelash, eyebrow, armpit, pubic and other body hair also falls out. Different doses of the drugs can cause from a mere thinning to complete baldness.
Fortunately, most of the time hair loss from chemotherapy is temporary and it regrows in three to six months after your treatment ends, though your hair may temporarily be a different shade or texture.
