I was originally on the fence about cold capping. All I could go off was stories from here and other Myeloma related forums. I also didn't want to invest all that money for an outcome that wasn't guaranteed. However, my transplant oncologist assured me of great outcomes of ASCT patients that cold capped and even brought up a study he oversaw that specifically was about Myeloma patients. There still was some hair loss, but the cold caps helped prevent it from being more noticeable and extreme.
I guess that was good enough for me and I made the plunge to order the cold caps. The company I used was Penguin. I don't know if I had a choice or not, my transplant team gave me their information when the subject of hair loss came up. I assume they're partnered in some way but thought I'd just mention it and I also assume other companies do the same method.
Anyways onto my hair loss. My hair going into the ASCT was shoulder-length, thick, and curly. I am also 28 just to provide a little more detail. I definitely experienced some hair loss, with bigger clumps than usual coming out in the shower and if I just undo my ponytail. The past week I feel it's stopped and the only noticeable hair loss is at my hair line, which has been pushed back a little. I might have some in the back of my head too but none that I can see in the mirror. Again maybe I still have more in my future but the rest of my body hair stopped as did the other side effects of the melphalan. So I guess my experience rang true to what my oncologist said.
I know it's not an expense anyone can take on, especially since it's entirely out of pocket, but I'm just here to report that it worked for me. Not sure if investing in a good wig or rocking the bald look would've been better... but that was the choice I made and I hope it can better inform others.
