Dear JaneinMelbourne,
That's good news. You can only try. It is uncomfortable at first for about the first 10min, and then gets easier.
It is similar to jumping in the pool. You adjust and get used to it. The temperature drops about 5 or 6 times until it reaches the cold temperature required.
I believe that if you don't use the Cold Cap, you loose your hair around the 2nd to 3rd treatment, so you should know then
if it is working. You will probably have some thinning.
Keep in touch. Let us know if it works or doesn't, or if you can manage or not.
You've got nothing to lose in trying.
Good luck with everything.
