Although I knew lack I was aware lack of selectivity of drugs, results in unintended actions, the reason why people on Chemotherapy lose hair was an eye-opener. I knew the science (cause), I knew the effect, yet I was unable to add 2+2. 🙁
A classic exmaples of this lack of selectivity is seen in most cancer chemotherapy drugs. These drugs kill rapidly diving cells – like cancer cells. Unfortunately, other cells that normally divide rapidly include the cells lining the gut, hair follicles, and the bone marrow cells that produce red and white blood cells. This is why cancer patients often lose their hair and become anaemic during treatmnet.
