I've also used the paxman cold cap. Had chemo 4 last week of fecx 6. Mine has thinned quite a bit and I have a balding bit on top (bit like an old man), but I still have lots of hair! I did lose loads during cycle 2 but It's definitely worth trying and I'm glad I did. I think mine has gone on top because the cap is probably not a great fit and my first session the machine wasn't working and I only realised 15 mins after them putting it on. So they took it all off to check the cap and machine. I then think they rushed putting it back on. At a glance no one would know as fringe, back and sides are all pretty good. I think it has made a huge difference to my confidence and mental state to keep my hair. I also wash it once a week with gentle shampoo and conditioner, I ash it in the shower with a jug using warm water. i have curly hair so the only time I use a comb is when I've washed it, the rest of the time I fluff it with my fingers. The first 5-10 mins are the worst and I take paracetemol 30-60 mins before treatment. Just 🤞🏻That I don't lose too much more.
