Couldn't attach a photo to my reply to Suzanne 333 (? can't tag you, sorry!) who posted about the cold cap. This is what it looks like. Consists of a brain-like contraption underneath, which is the part that freezes & then the 'cap' or hat part goes over the top & holds it in place, by use of straps which tighten in various degrees.
Happy to answer any Q's about it, or the process to anyone who doesn't know about it. I thought it worked great, & kept my hair, albeit it thinned a little.
