I was cancer free until 2022 and then was diagnosed with stage 4 breast cancer, metastasised into bones and liver. So I don’t think the cold cap had any link to it in my case. Despite being on medications that could have hair loss as a result, I’ve so far kept mine. Acupuncture, homeopathic tincture and Champo hair growing serum with a massage brush might have contributed to this. Also supplements like kelp, vitamin D and calcium, selenium. I told you I am obsessive about my hair! You’d think I’d have more things to worry about, haha.
