I had the same TPF IC as Don, and lost all my head, and body hair, fingernails and toenails too, and did not have radiation with it. It's was probably more the Taxotere, and 5-FU, I believe, but will never know. Still, cisplatin can cause hair loss, not that it will. Radiation alone made the hair come out in the radiated field. I didn't have to shave for months, then I had Taxotere, with
Erbitux, another time, with radiaion, and hair thinned again, coming out in the shower escoecuakly. Again, I think it was the Taxotere on the top. Radiation slightly on the side. My hair is thinner now, less thick, but my hair stylist knows how to cut it. I'm stil lucky being 52 with head hair lol. Good luck.
