I'm like Cathi, and had Taxotere, Cisplatin, and 5-FU with significant hair loss, but not totally, except for a few sprouts, which looked like my head was set on fire with scabs and few hairs, so it was shaven off, but grew back by 6 months more thin, lighter. Radiation was done as mono treatment and caused hair loss in the radiated field, especially the nape of the neck, sides. Then radiation with concurrent Taxotere and Erbitux caused hair loss in the radiated field again, and more thinning. My barber does an excellent job to cut my hair, and would not know of any loss, except for myself. I think my hair is like weed lol.

Cisplatin can possibly cause some hair loss on it's own as indicated as possible "side effects" in some literature, but never heard of any significant losses, and most have a combination of treatments anyway, so it's hard for them to say which really was the cause. I don't think you have to be worried like other cancer treatments causing complete baldness.

The cooling of hands, feet, head, chewing of ice is cyrotherapy to reduce side effects from certain chemo's, such as Mucocitis, hand and foot syndrome, neuropathy, and hair loss, by slowing down the uptake of the chemo in fast dividing cells.
