Tagrisso and hair dye

Following a week of usual activity, swimming, golf and tennis I was taken to A&E on a Friday evening in April with a suspected stroke causing weakness on my left side. I was shocked but not as much as the next morning when I was told I had two brain tumours and these must be a secondary cancer. I had further scans on the Tuesday revealing primary cancer in my lung. I had absolutely no symptoms so was in a total state of shock. Turns out I had multiple brain metastasis and chemotherapy and tagrisso were started very quickly. Life has been a bit of a blur since then and I try not to think about what the future holds for me. I’m feeling better in myself now chemotherapy has stopped and I’m just on Tagrisso. I may be 60 but I I’ve always liked to take care of myself and my appearance as it makes me feel better about myself. I’ve always had my hair dyed using a peroxide dye but I can’t seem to get an answer as to whether this is a good idea or not. Just wondering if anyone else has done this?
