Bad luck but take heart, some of us found chemo not as bad as feared. But yes, the hair did go. Most people report about a fortnight after the first infusion - mine went bang on schedule. Just a lot of hairs, no lumps or hanks, but I had my hairdresser at the ready and she cut my hair very short that morning (number 3 clippers) which saved a lot of mess. Some people shave their head but I felt that was a bit sudden! The rest followed inexorably - I wore a cotton night cap (your scalp may feel quite sensitive a week or so before hair starts to fall) and could just shake it all out in the bathroom sink each morning!
I only had one useable arm for needles ( lymphoedema after surgery, a whole other story) and I managed through 6 months of chemo without a line or port, but many find a vein saver preferable.
You might like to think about how you treat being bald - the Sinead approach (my skull just wasn’t such a good shape!), scarves and hats, or a wig. Many of us end up with a combination of all. I worked through chemo (as I said, not as bad as I feared) and a synthetic wig was great. No-one knew unless I told them. Everyone has their own preferences. Very best wishes.
