My hair only turned white! I didn't take radiation, but at least I'm now okay. My cancer was considered a very aggressive form, which meant the chemo was needed. But hey, I'm sixty, my grandchildren say I now look like St. Nick. lol. :)
it depends on what type of chemo you have. some will and some won't. most have other side effects as well...nausea, high or low blood pressure, low blood counts that require isolation from others to keep the patient alive because their body can't fight off germs. sometimes when a person's hair falls out, it will come back in a different color or texture. i once saw a woman who had straight brown hair, get curly red hair back. check with an oncologist for the side effects of which ever chemo you are interested in.
