I don't quite understand what you're asking but is it the method where you freeze your head to stop hair falling out or something similar? I did see that on tv but don't know if it's available yet, it did look very uncomfortable.
If your hair has started to fall out it likely will keep coming out in big clumps until all has gone or just leaves wispy bits. I went to the wig library and got a wig and scarves to wear. I must say that although this is supposed to be the worst thing to happen I, like a friend told me, found it great. It was so quick to get ready, no hair to wash, dry and style. Just shower, put on a scarf/knitted cap & you're done.
I was a bit peeved when it came back long enough that I had to start washing it again. Had some laughs with the wig too.
Hope all is going as well as it can be during your chemo.
