Black nail polish for chemo

Thank you all. I still put on the black nail (just in case).  :)

@dada I used black nail polish all through chemo and beyond. I didn't lose any nails, but they thickened and got ridges. 10 months after the end of chemo, my fingernails are only VERY slowly becoming less thick and uncomfortable, and are no longer flaky. A few of my toenails lifted, including the two big toes. They are still a problem, because wearing closed shoes (now that the weather is cooler) puts pressure on them and I've ended up with both big toes bruised black under the nail from the pressure. 
It seems there's no clinical evidence to support wearing of dark nail polish, but I figured if anything MIGHT help ... besides which, the loveliest thing was that my daughter and a couple of friends here, plus two friends in France, wore black nail polish all through my chemo in solidarity with me!

Hi @Dada. I used black nail polish on my toes during TC. I lost three toe nails and they all discoloured. I didn't use it on my finger nails. They all badly discoloured and none fell off, though they did get very 'loose'. The damage grew out, and then the nails were incredibly soft and constantly broke. It was a full year before they were back to normal. K xox

Hello @dada
My understanding is that dark nail polish is used for cosmetic reasons only to cover the nails, Im not aware of any evidence supporting the use of dark nail polish during chemotherapy.  See below information from the BCNA website regarding nail care which mentions the use of nail strengthener.

All the best with your 3rd round of chemotherapy,
kind regards

Many people use dark nail polish to counteract the effects of taxane type chemo which can play havoc with nails - discolouring, lifting, thickening etc. I didn’t and I only got a very light, almost unnoticeable tan film on my fingernails, nothing else. My toenails, covered most of the time, thickened and went black, brown, grey and chalk white. I didn’t lose any but some lifted. So don’t think it’s sunlight! It’s the chemical reaction, and as with nearly all aspects of chemo reactions, it varies enormously. Good luck whatever you decide.

You are correct @dada I wore gloves during winter which I felt was protection enough as my nails didn’t get too much any sun. Having said that, I lost three toenails which were very protected but no fingernails. Go figure. However the theory is, the chemicals from treatment react to the sunshine and so we need to protect our nails.
