My husband lost his hair with Cisplatin and radiation for snuc as well. His hair was getting thin anyway, but started coming out in bunches by the around the 3rd week after starting Cisplatin. He has also lost the hair on the right side of his face and upper lip from radiation. Amonth and a half after his last chemo/radiation his hair is coming back in- was very light at first but getting darker. It is pretty thin though.
A small price to pay for all the other side effects that go with the chemo/radiation- nausea, mouth sores, feeding tube, fatigue, etc.
It's hard to watch :-(
