i finished my chemo for her2 br/cancer just over a year ago and my nails just keep on peeling back thin. I had the hardest nails around,you could not bend them,they were good. now they are thin and disgusting , will they go hard again and how long will it take. I am running out of patients,I am sick of them peeling thin.Its so annoying.I think a year and a half they should be back to normal by now. Please help me with more info.
